It is a tool that caters to Omron’s C-series PLCs, CV-series PLCs and allconnectivity options.Note:Programming Using SYSWINCommandConnection to the PLCThe CPM1A or CPM2A can be connected to the PC via an RS−232C cable. One end of the RS232C is connected to the PC serial port (either 9 pin or 25 pin adapter), while the other end of thecable which is to be connected to the RS−232C adapter attached to the CPM1Aor CPM2A. The DIPswitch of the adapter must be set to Host in order to link to the PC.
The cable can also be connectedto CPM2A through the built-in RS-232C port provided.Response•SYSWIN is provided without token or dongle only to program CPM1 and CPM1A. For C-series,and CV series PLCs, token or dongle is necessary.Dip SwitchSet to HostRS−232CAdapterCPM1A CPURS232C Connector ConfigurationIBM PC/AT or CompatibleSignalPinFG1RD2SD3DIR4SG5DSR6RS7CS8--9RS−232CPin123456789SignalFGSDRDRSCS------SGThe wiring connection of CPM2A and CPM1A is the same.5-15.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINInstalling SYSWIN ProgramThe CPM1A training kit comes with three SYSWIN installation disks.
The SYSWIN program canbe setup in Windows 3.1 or 3.11, Window 95,98 or Window NT 4.0. To install, select RUN fromthe START menu. The following dialog box will appear, enter a:\setup.exe in the command line,click OK to execute and follow the directions as they appear on the screen.Once installation is completed, two Program Group icons will appear in the Program Manager.
TheSYSWIN samples contains sample programs whereas SYSWIN contains the necessary program torun SYSWIN. To execute SYSWIN, double click on the SYSWIN icon.5-25.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINSYSWIN WindowProgram Window TitleMenu BarSYSWIN toolbar & KeysBlock Header BarDrawing ToolsDrawing Tools Keys(or F Keys)Ladder ProgrammingWorkspaceScroll BarAddress BarInstant Help & Status BarStart Up With SYSWINSelect New Project from File menu.

Click on the symbol and move the symbol to anywhere in the windowand click to release. The address of the contact must be specified and key into the address dialogbox. In this example, 000.00 is entered.The address of the specific contact will be labeled on top of each component as shown.5-45.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINEach particular model of PLC has its own address for input and output, check the catalogue for eachtype of PLC. The address 000.00 represent address of the contact, the first three zero represent thechannel number and the other 2 zero after the decimal represent the particular bit of the channel.Continue with the rest of the sample program by clicking on the respective symbols from theDrawing Toolbox.DrawingTool Box5-55.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINAddNetworkNote that each line of the ladder program is classified as a network.
So in order to create anotherline, click the icon Add Network (Shift+F6) from the Toolbox to insert another network. Thedialog box shown below appear when icon is clicked. Select below current network and click OK.The same program will end with an end instruction line. In order to insert the end command, clickon the FUN icon on side of the window, move it to the location to end the program, click to execute.A function dialog box appear, requiring you to enter the function number to execute.5-65.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINTo browse for the types of functions available, lick on the select button. The select function box willbe shown.Saving the ProjectAfter completing the ladder diagram, the project must be saved.
Select Save Project in the file menu,a save project dialog box appear as shown below. Enter the file name e.g. test.swp in the file namebox with a .swp extension. Click OK to start saving.5-75.WINDOW BASED PROGRAMMING SOFTWARE-SYSWINTransfer Program to PLCBefore down loading program to PLC, first check the connection of the PLC to your PC. Next,select Communication under the Project menu to setup the serial communication setting of the PLCto PC.
Select the port of the PC where RS232C is connected, the baud rate for the communication,and the type of protocol to be used. Default setting of CPM1A is COM1, 9600 Baud, Unit 00,Protocol ASCII 7 bit Even Parity 2 stop. Click Test PLC to establish connection. Monitor the statusbar to check whether connection is successful.Once connection established, click download under on−line menu to download the complete ladderdiagram to PLC.
Select whether to include the expansion function or memory allocation. It isusually prefer to clear program memory of PLC before downloading the program. Click OK uponconfirmation.Uploading of program from PLC to PC is also possible. Select detect NOPs (no operation) for theoptions as shown.Finally when uploading or downloading completed, a download or upload successful dialog boxwill appear.Note:All application examples in this manual can either be programmed using window based SYSWINSoftware or the Programming Console.5-86.qAPPLICATION EXAMPLES OF BASIC COMMANDSOverview of InstructionsThe CPM1A has a large selection of programming instructions that allows for easyprogramming of complicated control processes.
