86 • Fieldbus Controller 750-841
Programming the PFC with WAGO-I/O-PRO CAA
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
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: www.wago.com
1. To start the WAGO-I/O-PRO CAA, click the Start menu item
Programs/CoDeSys for Automation Alliance/CoDeSys V2.3/ CoDeSys
V2.3 .
A dialog window will open. Select the target system for programming.
2. Choose WAGO, 750-841, Ethernet 10/100Mbps controller from the pull
down list and click the OK button.
3. You can now create a new project in WAGO-I/O-PRO CAA via its menu
item File/New. A dialog window will prompt you to select the programming
language (i.e., IL, LD, FBD, SFC, etc.).
4. To access I/O modules of your node, the module configuration must first be
mapped in the file "EA-config.xml". This file defines which system has
write access to each particular I/O module (i.e., the IEC 61131-3 program,
MODBUS TCP Fieldbus, or Ethernet IP Fieldbus).
This file can be generated in two different ways:
- in WAGO-I/O-PRO CAA
- in the “EA-config.xml” file stored in the controller.
Configuration with WAGO-I/O-PRO
1. To configure the I/O of the fieldbus node in WAGO-I/O-PRO, select the
Resources tab in the left window of the screen, then double click on PLC
configuration in the tree structure.
2. The tree structure for the PLC configuration is displayed in the center
window. Click on the plus sign (+) in front of Fieldbus Assignment to
expand the tree structure, which then displays the text Controller[FIX] for
the 750-841 controller.
