2.4 Communications with MP-series Controllers
When using Ethernet communications between the MP3000 and other MP-series Controllers, use the
Extended MEMOBUS protocol as the communications protocol. The Extended MEMOBUS 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.
