2.8 Communications with an OMRON PLC (FINS Communications Service)
When using Ethernet communications between the MP3000 and an OMRON PLC, use the FINS protocol
as the communications protocol. The FINS protocol allows the master to read and write 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 I/O message communications
or the MSG-SNDE function.
Using Automatic Reception with the MP3000 as a Slave
This section describes how to communicate with an OMRON PLC by using automatic reception.
When an OMRON PLC is used as the master to execute FINS commands, it will need a ladder application
that uses the following commands.
• SEND instruction: Writes I/O memory data from the OMRON PLC to the MP3000.
• RECV instruction: Reads register data from the MP3000 into the OMRON PLC.
• CMND instruction: Used to create any FINS command, including I/O memory read and write commands.
The CMND instruction sends FINS commands directly. The FINS commands must be created in the
ladder application.
