File Number / Tag Names for Explicit Messaging
The tables below detail the naming convention to use when creating explicit messages
within RSLogix. In the left most column is the native MW100 register starting with I/O
channels – 001 through 060, MATH channels A001 through A300 (also known as Math
Channels), and finally Communication Channels C001 through C300. I/O Channels and
MATH channels are considered read only while Communication Channels are read/write.
To the right of the MW100 register are the naming conventions that are used within
RSLogix messages. In an RSLogix 500 message, N10:0 would be used to retrieve an
MW100’s I/O Channel 001 as a 16-bit integer. In an RSLogix 5000 message, real[3299]
would be used for read or write requests of an MW100’s Communication Channel C300
as real. If a message was used to read MATH channel A060 as long integer from an
MW100, RSLogix 5000 would use dint[2059] as the Source Element.

With N file or CIP int tag, you can access to the data as short integer (word.)
With L file or CIP dint tag, you can access to the data as long integer (double word.)
With F file or CIP real tag, you can access to the data as real (float.)
MSG Instructions That the MW100 Supports
When using RSLogix 5000 and RSLogix 500 there are different types of messages that
correspond to the different type of PLCs. Everything from PLC 2 through an ControlLogix
PLC can be communicated with using the MSG block. The following covers all the MSG
instructions supported by the MW100 with EIP.
MW100 supports following MSG instructions.
• PLC2 Unprotected Read/Write
• PLC5 Word Range Read/Write
• PLC5 Typed Read/Write
• SLC Typed Read/Write
• CIP Data Table Read/Write
• CIP Generic Read/Write
Step by step examples of explicit messaging within RSLogix 500 and RSLogix 5000 are
detailed in appendix 8.
