Use the ControlNet
Communication Modules in
a Control System
ControlLogix controller with 1756-CN2(R)
or 1756-CNB(R) module as the scanner.
For a redundant system you
must use a 1756-CNB(R)
communication module. The
1756-CN2(R) Series A module
does not support redundancy.

In this example:
IMPORTANT
• The controllers, for example CompactLogix, ControlLogix, FlexLogix,
SoftLogix or PLC-5C can produce and consume tags among each other.
• The controllers can initiate MSG instructions that send/receive data or
configure devices.
• The personal computer can upload/download projects to the
controllers.
• The personal computer can configure devices on ControlNet, and it can
configure the network itself.

If you are creating a ControlNet redundant system you will
need to use a 1756-CNB module and refer to the
ControlLogix Redundancy System User Manual,
1756-UM532. The 1756-CN2 Series A module does not
support redundancy.
