Communication Parameters in the online menu and create a new
communication channel.
Choose EthernetTCP/IP (3S TCP/IP driver).
Enter the IP address of the coupler under “Address“ (e.g. 192.168.1.12).
Enter port number 2455.

Note
If the program should be permanently stored and be available without re-
newed download on the Controller after a voltage failure, the menu “Online”
-> “Create Boot Project” is selected in the logged in condition. Thus the com-
piled project is stored zero potential protected in the Flash memory. So that
the Controller starts the program automatically after voltage return, the mode
switch (fig. 1) is to switch into the upper position „RUN “.
2.5 Alternative to the Variable Declaration in the PLC Con-
figuration
Instead of addressing bits individually and globally in the PLC configuration,
a whole byte can also be addressed locally in the declaration part of the “PLC-
PRG“ program.
Open the “PLC_PRG“ program under the “POUs“ register and declare the lo-
cal process image as follows:
Input_Byte AT
%IB0:
BYTE;
Output_Byte AT
%QB0:
BYTE;
Fig. 17: WAGO-I/O-PRO CAA, Declaration and statement part of the PLC-PRG program
A simple assignment in the statement part of the program could be:
Output_Byte := Input_Byte;
