Communications with a JTEKT PLC (TOYOPUC Protocol)
When using Ethernet communications between the MP3000 and a JTEKT PLC, use the TOYOPUC proto-
col as the communications protocol. The TOYOPUC protocol allows the master to read and write to the
slave registers.
This section describes communications when the MP3000 acts as a slave and as the master.
When the MP3000 acts as a slave, communications can take place using automatic reception or using the
MSG-RCVE function.
When the MP3000 acts as the master, communications can take place using the MSG-SNDE function.
Using Automatic Reception with the MP3000 as a Slave
This section describes how to communicate with a JTEKT PLC by using automatic reception.
When a JTEKT PLC is used as the master to write data to the file memory in the 2PORT-EFR, you will
need to create a ladder application that uses the SPW instruction.
The SPW instruction is used to write data to the file memory in the 2PORT-EFR.
Refer to the following manual for details.
