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

BACnet/IP Controller
To ensure that you can access all bus module data properly in your new pro-
ject, first compile the bus module configuration based on the existing fieldbus
node hardware and map it in the configuration file "EA-config.xml". This file
defines whether write access is permitted to the modules from the IEC 61131-
3 program, from the MODBUS/TCP or from BACnet.
As described below, this file can be generated via configuration using the
WAGO-I/O Configurator.
3.1.8.1 Configuration Using the WAGO I/O Configurator
The I/O Configurator is a plug-in incorporated into WAGO-I/O-PRO CAA for
determining addresses for modules at a controller.
1. In the left half of the screen for the WAGO-I/O-PRO-CAA interface, select
the tab Resources.
2. In the tree structure click PLC configuration. The I/O Configurator then
starts up.
3. Expand the branch Hardware configuration in the tree structure with the
sub-branch K-Bus.
4. Right click on K Bus or on an I/O module to open the menu for adding and
attaching I/O modules.
5. Click on Append Subelement in the context menu. You can now select
the desired I/O module from the I/O module catalog and attach it to the end
of the K-bus structure using Insert and OK. In this case, the command "In-
sert element" is deactivated.
6. To insert an I/O module in front of a selected I/O module in the K Bus
structure, right click on an I/O module that has already been selected and
then click Insert element. In this case, the command "Insert sub-element" is
deactivated.
You can also access these commands with the "Insert" menu in the main win-
dow menu bar. The dialog window "I/O configuration" for selecting modules
is opened both by "Attach sub-element" and by "Insert element." In this dialog
window, you can position all the required modules in your node configuration.
7. Position all of the required I/O modules until this arrangement corresponds
to the configuration of the physical node. Complete the tree structure in
this process for each module in your hardware that sends or receives data,
either bit-by-bit or word-by-word (data width/bit width > 0).
