2.10 Communications with a JTEKT PLC (TOYOPUC Protocol)
Using the MSG-SNDE Function with the MP3000 as the Master
2-281
File Memory and Corresponding Registers in the MP3000
The following table shows the relationship between registers in the MP3000 and the receive data area of file
memory in the 2PORT-EFR.
Regardless of the connection number of the 2PORT-EFR, the MP3000 can store the data from any hold
registers into the receive data area in the file memory.
To specify the data to send, use the data address parameter (PARAM14 and PARAM15) and the hold reg-
ister offset parameter (PARAM20, PARAM21 and PARAM22) of the MSG-SNDE function. Thus, if
PARAM14 and PARAM15 are set to 10,000 and PARAM20 and PARAM21 are set to 20,000, and
PARAM22 is set to 0, the data sent to the 2PORT-EFR will be read out of the registers from MW30000,
which is the sum of MW10000 and MW20000.
Note: The data address setting and hold register offset setting in the MSG-SNDE function allow you to make any address
between MW00000 and MW65534 the first address of the send data.
