Appendix A – Detailed Explicit and I/O Messaging us-
ing RSLogix
®
The majority of devices that the MW100 will be connected to using EIP will be Allen-Bradley PLCs. RSLogix 5 ® , RSLogix 500 ®
or RSLogix 5000 ® are the programming packages used to confi gure and program everything from the legacy PLC 5 ® through
the latest ControlLogix ® CPU.
Explicit Messaging with RSLogix 500 ®
The following assumes basic familiarity with RSLogix 500 ® and RSLinx ® and that both are installed and RSLogix 500 ® is able to
communicate through RSLinx ® to the designated PLC.
Messages are designated as MSG under the Input/Output tab of the instruction bar and may be inserted as the output of a rung
of ladder logic. The MSG command can be used for reads or writes (the example below shows a write message). The target
device should be set to 500CPU when talking to SLC 500
® and PLC 5 ® for communicating to older PLC 5 ® . Control Block is used
to set the location in memory for the MSG function to be stored and it should be different from the Data Table Address used on
the Setup Screen (what data should be written to the MW100).
