Rockwell Automation 1785-ENET USER MANUAL PLC-5 ETHERNET INTERFACE - Manual (Page 37)

1785-6.5.19 November 1998
Communicating via the Interface Module 4-7
To communicate through a ControlLogix 1756-ENET module, you
configure the multihop feature of a MSG instruction from the
Ethernet PLC-5 processor (or PLC-5 processor with 1785-ENET
sidecar module) to the target device. You need RSLogix 5 programing
software. For more information, see the MSG instruction in the
PLC-5 Programmable Controller Instruction Set Reference Manual,
publication 1785-6.1.
If you want to go through the ControlLogix 1756-ENET module and
out the 1756-DHRIO module to the target device, you:
• use Gateway configuration software to configure the
1756-DHRIO module routing table in the ControlLogix system.
• specify a Link ID number on channel properties for channel 2/3A
of the Ethernet PLC-5 processor (or PLC-5 processor with a
1785-ENET sidecar module).
For information on specifying the path of the MSG instruction, see
the documentation for your programming software.
Interpreting Error Codes When the processor/interface module detects an error during the
transfer of message data, the processor sets the .ER bit and enters an
error code that you can monitor from your programming software.
