Programming the PFC with WAGO-I/O-PRO CAA

3.1.8 Programming the PFC with WAGO-I/O-PRO CAA
The WAGO 750-841 Programmable Fieldbus Controller (PFC) combines the
functionality of an ETHERNET fieldbus coupler with the functionality of a
Programmable Logic Controller (PLC). When the PFC is used as a PLC, all
or some of its I/O modules can be control locally with the use of WAGO-I/O-
PRO CAA. WAGO-I/O-PRO CAA is an IEC 61131-3 programming tool that
is used to program and configure the 750-841 PFC. I/O modules which are
not controlled locally (i.e., not controlled as a PLC), can be controlled
remotely through the 10/100 Mbps ETHERNET Fieldbus port.
Note
To perform IEC 61131-3 programming in the 750-841 PFC, the WAGO-I/O-
PRO port must be enabled. Enable and Disabling of this port is done with a
checkbox in the "Port configuration" web page.
The purpose of this section is not to provide a comprehensive lesson on
WAGO-I/O-PRO CAA programming. Instead, it highlights important
programming and configuration notes of the IEC 61131-3 program when it is
used with the 750-841 PFC.
More information
For a detailed description of how to use the software, please refer to the
WAGO-I/O-PRO CAA manual. An electronic copy of this manual can be
found on WAGO's web site:
1. To start the WAGO-I/O-PRO CAA, click the Start menu item
2. Choose WAGO, 750-841, Ethernet 10/100Mbps controller from the pull

mapped in the file "EA-config.xml". This file defines which system may
have write access to each particular I/O module (i.e., the IEC 61131-3
program, MODBUS TCP Fieldbus, or Ethernet IP Fieldbus).
