If you press the Go to Network button, the Statement List Editor opens and the line in error will be highlighted.

The error can then be corrected and another error chosen from the report dialog. If this information needs to be kept, then the Copy button copies the report to the Windows clipboard to be used by other programs. The Close button closes the dialog. These allow you to scan a program for all occurrences of any label, address, bit, channel, register or instruction and to change them globally.

Searching for Data If you wish to look at a program, or part of it, without making any changes, use the Edit Find command. The dialog allows you to narrow the search in several ways. Similar options exist in the Edit Replace dialog.

Type You can search by Address or its symbol name for example: AR5. The type you select affects the validity of the information you enter into the Find fields. Direction For searching purposes, the starting point is taken from the cursor in the current network, and from here you can begin a search Up or Down the program. Scope You can choose to search just the current block or all blocks. Enter address symbol names in full for a successful match. Other data can be partially entered, such as searching for generic addresses.

If you are looking for only one item, it is not necessary to enter anything in the Find To field. Neither field is case-sensitive. The Exact Match option forces a search only for the items you have entered in the Find fields. This is particularly relevant when you wish to replace items, as it is possible without exact matching to change something unintentionally. To help with specifying items to match, the table below gives examples and notes for each type of item.

Replacing Data The dialog for the Edit Replace command is similar to that for Edit Find, but there are some additional options. Replace Options Use the Find Next button to locate the next matching item from your specification. The appropriate element is highlighted in the ladder workspace. The Replace button changes just that element, and you must then use the Find Next button again to move on.

If you are satisfied that the correct element has been located, and you then want to make a global change, pressing Replace All changes all occurrences of that address, from that point to the end of the Scope. Prompt Replace When you select the Replace All option, you can choose to be prompted each time the specified symbol is found.

This is a safer way of doing global replacements, especially with complex searches. For example: use Searching for a channel will match channels, bits and indirect channels: Exact Match will match only channels, for example, AR2 will only match AR2, and not AR2. Searching Const16 will match Const16 and Const32, if Const32 values are only 4 digits long, for example, will match and Examples of matching possibilities.

Move Symbols When you select the Move Symbols option, the address symbol information is moved when the address is first found and then replaced. When an address is highlighted in the Address list, the list of cross-references is displayed for the selected address.

If you click on a cross-reference, the ladder editor display moves to the network containing the reference. This is called calculated replacement, where an offset is calculated from the Find item, and applied to all items that fit the specified range. In this case, it is only necessary to specify the start of the range of items to be replaced.

Examples of address replacement. Find Address You can quickly find the references for any address by typing in the Find Address field. When an address is highlighted, the list of references for that address is displayed. The Address list is updated for the new network. If you have changed the current network by clicking on cross-references, you can update the Address list by clicking the Current button.

Go To If you have a cross-reference entry highlighted, you can close the Address Cross-Referencer and edit the current network using the ladder editor by pressing the Go To button. A quicker way to edit the current network is to double-click on the highlighted cross-referencer entry. For example: addresses and are detected in a CMPL instruction. For example: addresses and are not detected in a BSET instruction.

Printing the Project Periodic hard copy printing may be necessary during project development, and the print options provided by SYSWIN are designed to make this easy and flexible. Projects can be printed in a range of formats, with as much or as little additional information as you require, giving you assistance with debugging and testing, as well as providing a permanent file record.

This displays a dialog with several print options, which allow you to build up the layout of your report. Unless you need a full listing for delivery or archive purposes, it is best to select only the briefer listings that are necessary.

Print Sections Front Page The front page information for the project is printed if this option is selected. The date and time of the printout are included. Block Overview This allows you to print an overview of the structure of the program by printing the block and network names.

Network comments can be optionally included. Options are available to allow you to choose to display only those features you require. Network comments may be included between networks and each network or group may be separated as required. Step numbers may be printed in the margins, and the Statement List and the Address List for the current network may be also printed. In order to structure your output to suit yourself, page breaks may be forced before every network, group or block. Selecting a Range of Networks You can select specific blocks and networks for printing by pressing the Range button.

This helps to reduce the amount of printing time when you wish to focus on particular areas of a program. You can print named networks by specifying the name in the Network Name field. You may find it easier to print selected networks by using the Block manager, marking the blocks or networks and then pressing the Print button.

Symbol Lists Symbol table listings can form part of the printout and can be sorted by alphabetical name and numeric address. The Purge option causes only those symbols that are actually used in the program to be printed.

Cross References This option provides listings which detail all symbols and addresses, showing where they are used in the program. The listing can be sorted alphabetically and numerically.

If the Outputs option is selected, all addresses used as outputs are listed in address sequence. The cross reference listing is most useful during debugging. Expansion Functions The list of expansion function mappings as used in the project can be printed. The printout shows the function number that have been allocated to each expansion slot. You can press the Setup button to review the settings and change them if necessary.

If you choose text mode you must specify the number of rows and columns available on a page the defaults assume A4-size paper. If you do not wish to print the report immediately, it can be saved to a file using the Text to File option; in this case, you need to specify the path and name for the file. Text Mode printing is designed for faster printing to dotmatrix and other slow types of printer.

This mode bypasses most of the Windows Print Setup settings, except for the selected printer port. This difference also affects printing, although it may be possible to select an appropriate character set on the printer itself.

Font This allows you to choose which Font type, size and style to use for the output for graphics mode printing. It displays a standard Windows Font setup dialog box including a sample box so that you can preview the type of text you have selected. Setting Up the Printer You can check the settings of the printer by pressing the Printer Setup button. This starts the standard Windows Print Setup dialog and is the same as selecting the File Print setup command. It allows you to select the printer to be used, the paper size and its orientation.

Your Windows manuals describe in detail the various options for your particular printing environment. You are able to monitor the operation of a program, including the memory data areas being modified by it, and interactively change instructions and data while the program is running or stopped.

These features of SYSWIN significantly speed up the commissioning of new equipment and the updating of existing projects. There are six elements of programming while connected which are covered in this section: s s s s s s. Establish the type of communications to be used Make sure that your computer is correctly configured to communicate with the PLC, and that you have the necessary cables to make the connection.

Check the project for accuracy and completeness Use the program check feature for verifying your project and the networks it contains, and make a safe copy of it, before making any changes while connected. Create a map for PLC memory area usage Note the variables that your program uses, and where these can be found in PLC memory for monitoring.

Connection setup, including communications Program downloading and execution Program monitoring Online program editing Editing the PLC memory areas Data trace and time chart monitoring. To ensure the most productive use of your time, you should have a clear plan for setting up the environment and working with the intended device before you connect to the PLC.

These must be specified, however, before connecting to the PLC and running a program. The Project Project Setup dialog should be reviewed to ensure that it is correct and that it matches the PLC actually being used.

You should also select the appropriate interface type for the connected session. Baud Select the desired communications speed bits per second which must match the speed set up in the PLC. Protocol Select the desired type of communications protocol, again matching that set up in the PLC.

If the link is working, the Status field will display Connected, and you are ready to begin other online operations. If the Status field displays Not Connected, check the parameters again, and try different speed and protocol settings, each time clicking on Test PLC to check the interface.

In most situations, it is not difficult to achieve a connection, but if nothing seems to work, use the Protocols button to access a more detailed setup of communications. You should remember that when programming libraries, you are not able to connect to the PLC.

If the Project Communications command is greyed out, check the Project Setup dialog to make sure that you are not working on a library or a template. You should switch on the PLC only after it has been physically connected to the computer. Detailed information about the types of connecting cable for your computer, and the advanced software setup, are provided in the reference manuals for your PLC and its associated communications hardware.

Having made the necessary cabling connection, you can switch on the PLC, and use the Project Communications command to set up the parameters and test the connection. In this dialog, use the list boxes to select each parameter.

Port Select the name of the port to which you have attached the PLC communications cable. Unit Enter the unit number of the PLC receiver.

Selecting a new mode changes the PLCs state immediately you accept the dialog. To ensure that you do not change the PLCs mode by accident, you should switch on the Confirm all operations that affect the PLC option from the Preferences Options menu.

You are reminded that the PLC will be stopped for the download, and asked to confirm that you wish to continue. The Download dialog provides options according to the type of PLC in use - not all options may be available at one time.

All items that you check in the dialog are downloaded to the PLC. Monitor Mode Allows a running program to be edited and monitored while connected during development. This is the most usual mode when working connected to a PLC. This mode is generally used for final testing, after a program has been thoroughly tested and debugged.

Expansion Functions The current mapping of the expansion function is downloaded. This is configured by using the Project Function mapping command. If you intend to use the online edit facility, this option should be set on. A status window then indicates progress, showing the percentage completed as the transfer proceeds, and a success or failure message. You must close this window by pressing Enter before continuing. The Online Verify program command compares the two programs and if they are the same, a message is displayed, and you can continue.

Another command that can be used to examine the overall program status is the Project Program check command. See the Advanced Projects chapter for details of this command. These markers are recognised during the upload process, so that uploaded programs are separated into blocks. You can select block markers using the Project Preferences command - see Advanced Projects in Chapter 7.

Markers appear only between blocks, so there is not one at the start or end of the program. This transfers the program and parameters from the PLC to the computer, and displays the ladder diagram in the programming workspace, as though it had been loaded from disk. You can upload at any time, regardless of the PLC mode. A program is always uploaded into an existing project, even if the project is empty.

Although it may be necessary to realign the network names and comments using the Insert and Remove buttons in the Network Symbol Editor , the general program structure is there to use. The Upload dialog allows you to select which parameters are to be transferred. The range of options depends on the PLC type. The setting up and maintenance of these parameters are described in detail in the Advanced Projects chapter of this manual. Expansion Functions The current mapping of the expansion functions will be uploaded.

These settings can then be edited with the Project Function mapping command. The information dialog is displayed using the Online Status command. It tells you the characteristics of the PLC, and the current execution status, including a list of any error messages generated by the PLC.

Not all errors can be cleared without operator attention. Power down and restart the PLC in order to ensure that the errors are cleared. This command may not be available for the particular PLC with which you are working. Mode While viewing the current status, you can change the PLC operating mode with this button.

Close Selecting this button closes the dialog box. The program asks if you want to convert your data - choose Yes and then Execute with the Move System Variables option checked. You may see a Process Program dialog screen. If so press Execute. Check that the program is correct Select the Project Program check command with all features switched on. Press Execute. Parts of the program in the workspace should then be highlighted to show the flow of execution. With the sample program running, the monitoring feature highlights sections of the program showing the execution sequence.

The data elements of appropriate instructions for example - the INC instruction in the example are also highlighted, showing the data values changing. However, remember that, because the communications link is considerably slower than the execution speed of the PLC, only a sample of the programs execution is displayed. The SYSWIN monitoring continues to show the progress of program execution visually in the workspace, even while other dialogs are open in front of it.

The monitoring is active until a network is edited, at which point the monitoring stops until the changed network has been verified and downloaded. If Show full powerflow monitoring is switched on in the Monitoring section of the Preferences Drawing menu, then the power flow is highlighted on the display.

It is usual to have the PLC running in Monitor mode while using online editing functions. Online editing is not possible in Run mode. Changing Networks Any change that you would normally make to a network while not connected can also be made while connected.

If Confirm all operations that affect the PLC is enabled, you are warned if you do anything that changes critical parameters within the PLC. Use the normal workspace controls to edit the program. The editing cursor changes to red as soon as you start changing the network.

This verifies that the original network is the same in the PLC and if so the new network will be downloaded to the PLC. If Automatically start monitoring after online edit is enabled from the Preferences Drawing menu, the monitoring restarts.

Working on networks while the PLC is connected and being able to easily change the program is one of the quickest ways to complete and check a project. With the PLC running in monitor mode, you are able to make any changes to the program, as if you were working while not connected.

The difference is that once a network has been completed, it is downloaded automatically to the PLC if necessary replacing the previous version while the program is running. Certain parts of SYSWIN are not available while online editing is active: the Block Manager is the main function that cannot be used, which in turn means that library import is not possible.

In order to use SYSWINs online editing feature, the Online Online edit command must be enabled - this menu option is a toggle, so each time it is selected, it alternately switches online editing on or off. If, in the Preferences Drawing command the option to automatically start monitoring after Online Edit is switched on, then monitoring automatically restarts after a network is downloaded. This error can be cleared using the Online Status dialog, but it is not necessary to do so.

When a bit address is right-clicked, such as on a contact, output or function with bit parameters, a small floating menu will appear. Two types of floating menus are displayed depending on the currently selected PLC. It is not possible to change the values of immediate parameters; you must use online editing to do this. If the Display option in the Preferences Drawing menu is enabled, then a pair of arrows is shown on the ladder diagram showing that the bit address is forced.

Note that the information on which addresses are being forced is discarded at the end of the current editing session. This information is displayed only for guidance. When a channel address is right-clicked, as found on most function parameters, you can enter a new value which is written down to the PLC.

When the monitoring values are being interpreted, it is assumed that the value that has been typed is the same format as is being displayed.

For example: if 0. When the monitoring values are not being interpreted, it is assumed that the typed value is hexadecimal. See Appendix B for information on the Format Specifiers. The diagram below demonstrates right-clicking on a parameter:. It is used during the testing of a program to change values of bits and channels in the PLC. It is enabled in the Windows section of the Preferences. When enabled it can display either 2 or 4 rows of data.

This allows you to input data in this area. Enter an address to monitor Press the Enter key or double-click the mouse. A dialog is opened into which you can enter the address that you wish to monitor. A Browse button is available so that you can select an address to monitor from the list displayed in the Address Symbol Editor. If no value is entered in the Address field then when you press Enter the value is read from the PLC.

If a value is entered then the value is written to the PLC when you press Enter. If monitoring is enabled, then the values change as the program is executed.

If monitoring is not enabled then the values are as displayed. If a bit address is entered for example: If it is incorrect you can change the format using the Format list. This means that you can examine in detail how the program is performing, and quickly find out if a data value is being incorrectly changed.

To gain a quick overview of how the Set command can be used, follow the steps given here with the sample program that was downloaded earlier: NOTE! Start the Set dialog Select the Online Set command.

Enter an address to examine Go to the first Address field and enter Then click on Read. The Value for that address should appear as 1. A number appears in the Value field for example: Change the data value and write it back Select the Value next to the HR1 address, and overwrite it with 0.

Then click on the Write checkbox to the right of the value. Click on the Write button to download this new value to the PLC. Monitor the data values Click on Start Monitoring. The data value against HR1 will now start changing as the program executes.

Through this simple example, you can see how to change data conveniently while still in the main SYSWIN programming environment, and how to monitor data values. Bit addresses in the Set dialog must be entered in the SYSWIN format, using a dot to separate the channel and bit address, for example: use Timer and counter flag bits must be entered with a.

F suffix, for example: TIM Using TIM would only refer to the channel. Display Addresses can be displayed in their absolute form or by their symbol name assigned with the Address Symbol Editor. Format Data values can be displayed in either hexadecimal or binary. Using this button while monitoring is in progress stops the monitor and effectively freezes the values on-screen. The program continues to run.

This option is useful if you wish to create or store particular test data sets for verifying the correct operation of a program after modification. A standard Windows file saving dialog allows you select a directory for the file and name it.

Load Data Data sets previously saved can be restored with this option. For the data to become effective in the PLC, you must use the Write button to download the new values.

Clear Fields Use this button with some caution, as it clears the entire list of addresses and data values. No change takes place in the PLC, but the information being viewed is cleared. With a long list, you may wish to save it to a disk file before clearing it, so that it can be restored quickly another time. This is independent of the program monitoring.

Once an address bit has been forced, it is locked in that state until explicitly cancelled, or the PLC restarted. The Force dialog for multiple addresses provides for the changing of up to ten address bits at once, and is used in a similar way to the Set dialog described above. Addresses and actions are selected, then executed by writing to the PLC; execution status is shown in the Status field at the bottom of the dialog.

If a large range is selected, this may take a few minutes. Display Addresses can be displayed in their absolute form or by a symbol name assigned with the Address Symbol Editor. Address Enter here only bit addresses that can be written to. A symbol can be used if it refers to a valid bit address. Clear Fields This button should be used with some caution, as it clears the entire list of addresses and actions.

No change takes place in the PLC, so any addresses that have been forced will remain so until you re-enter and cancel them. If you have created a list of several items, you may wish to save it to a disk file before clearing it, so that it can be restored easily another time. Forced Addresses Forced addresses when read display a list of current force set addresses and their state. This list is current only at the time of being read and does not reflect changes made by other devices or software packages.

However, this is possible only in the Monitor mode. If you attempt to write while the PLC is in Run mode, an error message is displayed. It writes to the PLC immediately for execution, but the selections in the Action fields do not change. Save Data The list of address and data values can be saved to a disk file for later use.

This option is useful for creating test data sets for verifying the operation of a program after modification. A standard Windows file save dialog allows you select a directory for the file and name it. Load Data Test data sets previously saved can be restored with this option. Read This button supplies a selectable list of memory areas to scan for Forced Addresses.

If any Forced Addresses are found they are appended to the Forced Addresses list box. Clear This button clears the list of Forced Addresses. If these are different then by pressing the Synchronise button, the time in the PLC is set to the same time as the PC. If you wish to set the time to anything other than the PC time then use the New time and date fields to enter the values and press the Set button.

The files must be selected first from both the Disk portion and Card portion of the display. Checksum The Checksum button checks the checksum of the selected file in the Memory Card. Rename and Delete The Rename button and Delete button allow you to rename or delete files from the disk or Memory Card. Refresh The Refresh button updates the display with the files currently on the Memory Card.

Select an area of memory and enter a valid range. An Action No. The Online Clear memory command will open a dialog showing memory areas for you to select to clear. Selecting the OK button accepts the settings and clear the selected areas. The Close button accepts the settings and closes the dialog. Format Card A Memory Card must be formatted before use. The Format Card button formats the Memory Card so files can be transferred. The Label Card button can be used to assign a name to the Memory card.

Disk The Disk portion of the Memory Card dialog shows the files, drive and directory which can be amended as necessary to transfer files to the Memory Card.

The program must first be set up with an open contact with the address AR The password protection can then be applied. The password can be any four digit number. To set the password, select Online Protect program to display the dialog and press the Set button. The protection can be released by pressing the Release button. The following example illustrates the functionality of the password protection, with the password of The Read button refreshes the Error Log display and the Clear button resets the display.

If this option is set, the Error Log is enabled. When enabled, the password is required every time the program is accessed.

Projects can also be protected with a password; refer to the Advanced Projects chapter. The Data Display Editor enables you to upload and download sections of PLC memory, and manipulate the data values as required.

The selection buttons that are displayed reflect the features of the PLC that you have selected. Many of the commands used in normal SYSWIN operation can still be used, however, including the file and online commands. When you open the Data Display Editor for the first time in a project the screen is blank.

However, each time it is opened thereafter it displays the last area viewed. The data formats that can be used in the Data Display Editor are shown in the diagram below.

These are helpful in creating sample data for testing programs and loading different sets of data. The File Print command provides you with printout of the current data area.

Status Bar The status bar at the bottom of the screen provides the following helpful pieces of information: Instant Help A brief message appears in the Status Bar as menu commands are selected. At other times, a description of the data area being edited is displayed. The address in the memory area where the cursor is currently located. The current status of the connection to the PLC. When reading from or writing data to the PLC, the percentage completed is displayed here.

Keyboard for Data Display Editor Using the keyboard during data display editing is as intuitive as when programming. The area selection buttons at the left of the screen, or their shortcut keystrokes, can be used to select a memory or data area to be examined and monitored.

Individual locations can be selected by clicking the mouse or navigating with the arrow keys. The Data Display Editor has its own toolbar and while some of the standard functions are provided, there are special functions for selecting the format of the data display and controlling online operations.

The display formats offer great flexibility in the way in which you can view PLC data. Cursor address Online status PLC mode. Memory holes are areas in the address space that do not contain any memory. In the Data Display Editor, the holes appear on the screen as red dashes These addresses cannot be edited. You need to begin by selecting the area of PLC memory that you wish to examine, as follows: Select the data area to edit Use the Data Area command to display the selection dialog, or just click on the appropriate area button on the toolbar.

Specify the range of locations within that area A dialog appears, asking you to select the entire area or part of it for display. For the moment choose All and press Enter. Select a suitable display mode Use the Data Format command to bring up a dialog, or just click on the appropriate format in the toolbar for example, DEC to display in decimal. If the PLC is connected, however, this is done automatically.

BCD display is a subset of hexadecimal, and shows values in the range Hex values are in the range 0-FFFF, and the decimal values are between 0 and Only the displayed area of the PLCs memory is monitored in the Data Display Editor, and the cursor changes to indicate when monitoring is in progress. When you select a new memory area, you are given the option to display the data in a new window. If you choose not to open a new window, the data in the current window is replaced. When selecting a new memory area, you can choose to display only a part of the area.

This feature is most useful when editing large memory areas, for example, the Data Memory Area. The current window will be displayed with a highlighted title bar. Using the mouse, you can change the current window by clicking inside any part of the window you wish to edit. When you have finished editing a memory area, you can close the current window using the File Close current data window command. The File Close all data windows command removes all the windows from the workspace.

Editing Data Items To change an item, use the arrow keys to navigate around the data area displayed, and press Enter when the item you want is highlighted. Alternatively, you can double-click on the item directly with the mouse. The data item is then displayed in its own dialog, giving you the opportunity to change it.

You can change the format of display and entry with the Format options. The value is displayed in three comparable formats for reference at the bottom of the dialog. If you are editing a few adjacent addresses, you can move to the next and previous data items with the buttons at the bottom of the dialog box, and the cursor in the data area behind moves with you. Any changes that you make are recorded as you move to another memory location and when you click on OK to close the dialog.

The Cancel button or the Escape key closes the dialog, ignoring the last change that you made, provided you have not moved to another item. Monitoring is switched off when you enter an editing dialog, and changed items should be downloaded to the PLC before re-enabling monitoring otherwise data items you have changed are overwritten with data read by the monitor.

When you use the Write command to update the PLCs memory, all locations are written, including those that may have been scrolled out of the Data Display window. The values of several memory addresses can be recorded and then analysed on screen. Trigger conditions and trigger delays can also be configured which assist debugging by allowing you to pinpoint specific events.

The editors are started with the Editors Data tracing and the Editors Time chart monitoring commands. While a Data Trace is executing, the PLC records the data values and holds them in an internal buffer. Data Tracing provides very fast and accurate data capture.

The display is updated as each sample is read from the PLC. Time Chart Monitoring provides slower and less accurate data capture; however, the sampling interval ranges from 0. SYSWIN retains the trace information after you have closed the editors; this allows you analyse the trace while examining the program.

You can change editor while a Data Trace is executing, but you may need to explicitly upload the trace from the PLC when you return to the Data Trace editor. If you are using the Time Chart Monitoring, sampling automatically stops when you close the editor. You can use the File Load trace file and File Save trace file commands to access stored trace files. If you are not connected to a PLC, you can still review trace information that has been stored previously.

Trigger You can set a trigger condition to occur when either a channel reaches a preset value or a bit address changes state. When the trigger condition occurs, the samples are recorded until the buffers are full.

You can use a latching circuit to achieve this.
