SLC 5/05 #2 Using Ethernet
For DF1-to-Ethernet passthru, SLC 5/05 #2 is the receiver and does
not require message ladder logic, only a correct IP address and
proper channel configuration.
For Ethernet-to-DF1 passthru, SLC 5/05 #2 is the initiator and must
have ladder logic. The program below shows how the SLC 5/05 #2
processor can initiate a message to the SLC 5/03 via the SLC 5/05 #1
bridge.
The SLC 5/05 message ladder logic, remote message setup, and
channel configurations are shown below.
