2.8 Communications with an OMRON PLC (FINS Communications Service)
Using the MSG-SNDE Function with the MP3000 as the Master
2-212
I/O Memory Data Areas and Corresponding Registers in the
MP3000
The following table shows the relationship between registers in the MP3000 and the I/O memory data
areas.
A read or write command is automatically generated by specifying the address in the MP3000 that corre-
sponds to the I/O memory to be read from or written to in the OMRON PLC.
Set PARAM14 and PARAM15 of the MSG-SNDE function to the register address in the MP3000 that cor-
responds to the address to read from or write to in the OMRON CPU Unit. Select whether to read or write
by setting the function code in parameter PARAM12 for the MSG-SNDE function.
Note: Word: Specify word addresses.
Writing Data into D10000
Set PARAM14 and PARAM15 to the MW10000 register in the MP3000 that corresponds to
D10000, and set PARAM12 to 0B or 10 hex.
Reading Data from W511
Set PARAM14 and PARAM15 to the MB025590 register in the MP3000 that corresponds to
W511, and set PARAM12 to 01 hex.
To access a relay, specify a bit address in PARAM14 and PARAM15.
