Programming the PFC with WAGO-I/O-PRO CAA
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
These libraries are loaded on the WAGO-I/O-PRO CAA CD.
After installing these libraries, you will have access to their POUs (Program
Organization Units), data types, and global variables, which can be used in the
same manner as user defined program objects.

3.1.7.2 IEC 61131-3-Program transfer
Transferring an IEC 61131-3 application program from your PC to the PFC
can be done in two different ways:
• via the serial RS232 interface
• via the fieldbus with TCP/IP.
Note
When choosing the driver, make sure the communication parameters are
correctly set and match your controller.
The Communication parameters dialog window is displayed through the
program menu item Online and then Communication parameters.
1. If you choose the RS232 driver, verify that the Communication parameters
dialog window contains the following setup data: Baudrate=19200,
Parity=Even, Stop bits=1, Motorola byteorder=No.
2. If you choose the TCP/IP driver, verify that the Communication
parameters dialog window contains the following setup data: Port=2455,
Motorola byteorder=No. Additionally, verify that the entered IP address is
correct.
