8-4 Communicate from an SLC 5/05 Controller to an SLC 5/03 Controller over an EtherNet/IP Network
Configure the Message
This is the setup screen for the example configuration.
The firmware in the SLC 5/05 controller must be capable of handling CIP
protocol. CIP protocol is what the 1756-ENBT module supports. The
firmware for the SLC 5/05 controller has been upgraded to handle both CSP
and CIP protocols. Refer to Knowledgebase document G16915 for minimum
firmware revisions needed for the SLC 5/05 controller to communicate to a
1756-ENBT controller. The SLC 5/05 controller needs to be at a minimum,
Series A, 0S501 Firmware 5.
In this example, the:
• The SLC 5/05 controller on
an EtherNet/IP network
with it’s IP address at
100.100.100.8.
• The SLC 5/05 controller
sends the message to an
SLC 5/03 controller on a
DH-485 network via the
1756-ENBT module at IP
address 100.100.100.7 over
the backplane to a
1756-DH485 module.
• The 1756-ENBT module is
in slot 10 and the
1756-DH485 is in slot 14 of
the ControlLogix rack.
• The SLC 5/03 controller is
connected to Channel A of
the 1756-DH485 module
and is communicating
through link couplers.
