2.9 Communications with a KOYO PLC (MODBUS/TCP Protocol)
When using Ethernet communications between the MP3000 and a KOYO PLC, use the MODBUS/TCP
protocol as the communications protocol. The MODBUS/TCP 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.
Using Automatic Reception with the MP3000 as a Slave
This section describes how to communicate with a KOYO PLC by using automatic reception.
Note: 1. Automatic reception uses 1-to-1 communications.
2. If you need to communicate with multiple devices, use the MSG-RCVE function.
