2.7 Communications with a Mitsubishi PLC (QnA-compatible 3E Frame Protocol)
Using the MSG-SNDE Function with the MP3000 as the Master
2-147
Device Memory and Corresponding Registers in the MP3000
The following tables show the relationship between registers in the MP3000 and device memory in the
Mitsubishi Q/QnA-series PLC. Use device addresses within the ranges listed in the tables below according
to the conditions of the Mitsubishi Q/QnA-series PLC slave.
A read or write command is automatically generated by specifying the address in the MP3000 that corre-
sponds to the device to be read from or written to in the Mitsubishi Q/QnA-series PLC.
To read data from or write data to the address specified in PARAM14 and PARAM15 of the MSG-SNDE
function, specify the register address in the MP3000 that corresponds to the device address in the Mitsubi-
shi Q/QnA-series PLC. Select whether to read or write by setting the function code in parameter
PARAM12 for the MSG-SNDE function.
* Access file registers by using the ZR notation for accessing continuous file registers. The R* notation cannot be used.
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 M001000
Set PARAM14 and PARAM15 to the MB005748 register in the MP3000 that corresponds to
M001000, and set PARAM12 to 01 hex.
Note: To access a relay, specify a bit address in PARAM14 and PARAM15. For MB005748, this would
be 9192 decimal.
