InWAGO-I/O-PRO CAA, this driver and its parameters are entered in theCommunication Parameters dialog.1. Start WAGO-I/O-PRO CAA by using the Windows Start menu, find andclick on the WAGO-I/O-PRO program name (i.e., CoDeSys V2.3).2. In the Online program menu, click Communication parameters.

In the center window of the dialog, the following parameters appear:Address=localHost, Port=2455, Motorola byteorder=No. Replace theAddress “localHost” with the IP address of your controller assigned via theBootP server. If necessary, change the other entries accordingly. After alldata has been entered, Click OK. You can now test communication withyour controller.NoteTo access the controller, it must have an IP address, and the operatingmode switch of the controller must be in the center or top position.5.
