Preface
Purpose of This Manual
This manual describes how to understand, configure and troubleshoot
your ControlLogix Data Highway Plus/Remote I/O communication
interface module (1756-DHRIO module).
This manual also provides step-by-step procedures on how to:
· use the 1756-DHRIO module to send DH+ messages between
ControlLogix controllers, PLCs and SLCs in DH+ applications.
and
· connect ControlLogix controllers to remote I/O and send block
transfers via the 1756-DHRIO module.
Throughout this manual, we describe ControlLogix systems that use
the 1756-DHRIO module and ControlLogix controllers. Multiple
ControlLogix controllers are available. The examples contained in this
manual do not call out specific catalog numbers for ControlLogix
controllers. Whenever a controller is shown, any of the
controllers
apply.
For a complete list of ControlLogix controllers, and a description of
each, see the ControlLogix Selection Guide, publication 1756-SG001.
