3.1.6.2 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.
•One suitable communication driver each is required for both types.
More information
For information on the installation of the communication drivers as well as details regarding the use of the software, please refer to the WAGO-I/O-PRO CAA manual (download: www.wago.com).

3.1.6.2.1 Transmission 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.: 759-333, 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 CAA, this driver and its parameters are entered in the
"Communication parameters" dialog.
1.Start the WAGO-I/O-PRO CAA software via ’Start/Programs’ or by double clicking on the WAGO-I/O-PRO CAA 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 and -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 CAA 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".
8.To terminate the online operation, return via the "Online" menu and click on the "Log-off" menu point.

3.1.6.2.2Transmission via the fieldbus
1.Start the WAGO-I/O-PRO CAA software via ’Start/Programs’ or by double clicking on the WAGO-I/O-PRO CAA symbol on your desk top.
2.In the "Online" menu click on the "Communication parameters" menu point.
The "Communication parameters" dialog opens.
3.Click on the “New” button to define a driver in the "Communication parameter" dialog.
4.Enter any name and mark the desired driver (i.e. "CANopenHilscher") in the selection window of the dialog.
5.Subsequently confirm with "OK".
The following entries have to appear in the center window of the dialog: - PCB number (number of the CANopen fieldbus PCB corresponding to your PC configuration), - Baud rate (the Baud rate of your controller set via the DIP switch) and – node number (the module ID of your controller allocated via the DIP switch).
If necessary, change the entry accordingly.
6.Change the entry - “Maintain” database into “Delete” database if you wish to delete previous settings from the database, and confirm with "OK".
7.The dialog window is closed and you obtain a message with the question whether or not to delete the database. Confirm this by again clicking on
"OK".
8.In the menu "Online", click again on the menu point "Communication parameter" and change the entry - “Delete” database to “Maintain” database.
9.Subsequently confirm again by pressing "OK".
The dialog window closes, the controller test can start.
Note
Prerequisite for the access to the controller is that the module ID and the Baud rate coincide with the settings at the controller, and that the operating mode switch of the controller is in the center or top position.
10.Under "Online" click on the "Log-on" menu point to log into the controller.
(During online operation, the WAGO-I/O-PRO CAA server is active. The communication parameters cannot be polled.)
11.If there is not a program contained in the controller, a window appears asking whether or not the program is to be loaded.
Confirm with "Yes".
Subsequently the current program is loaded.
12.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".
13.To terminate the online operation, return via the "Online" menu and click on the "Log-off" menu point.
