Appendix 8 Detailed Explicit and I/O Messaging
using RSLogix
The majority of devices that the MW100 will be connected to using EIP will be AB PLCs.
RSLogix 500 or RSLogix 5000 are the programming packages used to configure and
program everything from the legacy PLC 5 through the latest ControlLogix.
Explicit Messaging with RSLogix 500
The following assumes basic familiarity with RSLogix 500 and RSLinx and that both are
installed and that 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 (in this case the example below shows a write message).
The target device should be set to 500CPU when talking to SLC 500s and PLC 5 when
communicating to older PLC 5s. 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).
