In order to communicate with the RIO interface on a ProLinx module, the Remote
I/O Scanner (usually a PLC) must be set up and programmed to scan the
interface. The example given in this document is for the Rockwell Automation
PLC5 processor. Other examples may be available on the ProSoft Technology
web site at www.prosoft-technology.com. Refer to this site for the latest
information on this and other ProLinx products.
6.1 Initial Setup
This section discusses the initial configuration parameters that must be set to
interface with the RIO communication module on the PLC5. Parameters set in
this configuration must match those set in the ProLinx module.
The first parameter that must be defined for the module is the rack size. This
parameter determines the number of words in the input and output images.
These words will appear in the I1: and O0: files on the PLC. Use the RSLogix 5
software to configure the 1B channel on the PLC as displayed below:
