Messaging Between ControlLogix Controllers
What This Chapter Contains
This chapter describes how to use Control and Information Protocol (CIP)
messaging between ControlLogix controllers with the1756-DHRIO and
1756-DHRIOXT modules.
Each of the following examples explains what steps you must take to perform the
described operations.
CIP Messaging Between
ControlLogix Controllers over
One Link
This application sends a CIP message from ControlLogix controller A through a
1756-DHRIO or 1756-DHRIOXT module to ControlLogix controller B
controller B. The following figure illustrates the steps you must use in this
application.
