3.2.8.2 IEC 61131-3 Program transfer
Program transfer from the PC to the controller following programming of the desired IEC 61131 application can be made in two different ways:
•via the serial interface or
•via the fieldbus.
3.2.8.2.1Transmission via the serial interface
Use the WAGO communication cable to produce a physical connection via the serial interface. This is contained in the scope of delivery of the programming tool IEC 1131-3, order No.: 759-332/000-002, or can be purchased as an accessory under order No.: 750-920.
Connect the COMX port of your PC with the communication interface of your controller via the WAGO communication cable.
A communication driver is required for serial data transmission. In WAGO- I/O-PRO 32, this driver and its parameters are entered in the "Communication parameters" dialog.
More information
i Please find more information on the installation of the communication driver and the detailed description of software handling in the manual WAGO-I/O-PRO 32 (order no.: 759-122 / 000-001).
1.Start the WAGO-I/O-PRO 32 software via ’Start/Programs’ or by double clicking on the WAGO-I/O-PRO-32 symbol on your desk top.
2.In the "Online" menu click on the "Communication parameters" menu point.
The dialog "Communication parameters" opens. The basic setting of this dialog has not yet any entries.
3.In the selection window mark the desired driver on the right-hand dialog side (i.e. "Serial (RS232)", to configure the serial connection between PC and the controller).
4.In the center window of the dialog, the following entries have to appear:
- Parity: |
Even |
- Stop bits: |
1 |
If necessary, change the entries accordingly.
You can now commence testing the controller.

Note
To be able to access the controller, ensure that the operating mode switch of the controller is set to the center or the top position.
5.Under "Online" click on the "Log-on" menu point to log into the controller. (The WAGO-I/O-PRO 32 server is active during online operation. The communication parameters cannot be polled.)
6.If there is not a program in the controller, a window appears asking whether or not the program is to be loaded.
Confirm with "Yes".
Subsequently the current program will be loaded.
7.As soon as the program is loaded, you can start program via the "Online" menu, menu point "Start".
At the right-hand end of the status bar, the system signals "ONLINE RUNNING"." gemeldet.
8.To terminate the online operation, return via the "Online" menu and click on the "Log-off" menu point.
3.2.8.2.2Transmission via the fieldbus
The field bus cable is the physical connection between the PC and the controller.
In TOPLON® PRIO the transfer of the IEC 61131 programm take place via Menue "WAGO-I/O-PRO\Download IEC 61131 Application".
