Overview
Ethernet Communications
Ethernet communications connects the MP3000-series Controller to Ethernet devices. The MP3000-series
Controller is equipped with one 100Base-TX Ethernet port that conforms to IEEE802.3u. It can be easily
connected to controllers manufactured by other companies, personal computers, or other types of comput-
ers. By connecting a computer running the MPE720 Integrated Engineering Tool, you can perform engi-
neering tasks on the MP3000-series Controller from the computer.
Ethernet communications can be used for message communications and engineering communications.
The MP3000-series Controller supports the following communications protocols.
The Extended MEMOBUS protocol is used for all message communications between the CPU Function
Module and the 218IFD Function Module in the CPU Unit or the CPU Module of the MP3000-series
Machine Controllers.

This manual describes message communications using the MSG-SNDE and MSG-RCVE functions. If
you use the MSG-SND and MSG-RCV functions, substitute the corresponding information for the
MSG-SND and MSG-RCV functions. These functions are slightly different when used in ladder pro-
grams. Refer to the following manual for information on using the MSG-SND and MSG-RCV func-
tions in ladder programs.
