In this hardware configuration, a remote PLC-5 controller sends a message to
an SLC 5/03 controller.
Communications Between a PLC-5 and a Remote SLC 5/03 Controller on a DH-485 Network
The PLC-5 controller sends a message to an SLC 5/03 controller located on a
DH-485 network.
•
The PLC-5 controller is located on a DH+ network.
(1)
•
The PLC-5 controller is connected to channel A on a 1756-DHRIO
module located at node 12.
(2)
•
The 1756-DHRIO is on the same backplane as the 1756-DH485
module and is located in slot 8 of the chassis.
