YASKAWA MP3000 Series - Using the MSG-SNDE Function with the MP3000 as the Master

2.10 Communications with a JTEKT PLC (TOYOPUC Protocol)
Using the MSG-SNDE Function with the MP3000 as the Master
2-280
Using the MSG-SNDE Function with the MP3000 as the Master
This section describes how to communicate with a JTEKT PLC by using the MSG-SNDE function.
When a JTEKT PLC is used as the master to read data from the file memory in the 2PORT-EFR, you will
need to create a ladder application that uses the SPR instruction.
Communications Format
The MP3000 acts as a master and sends data and receives responses using the communications formats for
file memory commands that are shown below. Execution of the MSG-SNDE function ends when the
response is received.
Note: In the figure shown above, the Ethernet header, TCP/UDP header, FCS and other items have been omitted. Only the data
portion of the communications format is shown.
The SPR instruction is used to read data from the file memory in the 2PORT-EFR.
Refer to the following manual for details.
