(1) Connection with MELSOFT products and a GOT
In Ethernet, a programming tool can create programming of a programmable controller and monitor a
programmable controller (MELSOFT connection), and the GOT can monitor and test a programmable controller.
Remote operations making full use of the Ethernet capability, long-distance connectivity and high-speed
communications, are achieved.
(2) Collection and modification of CPU module data from connected devices (MC
protocol communications)
The MC protocol enables connected devices to access MC protocol supporting modules over Ethernet. The E71
can communicate with a personal computer and HMI (Human Machine Interface) as long as the connected
devices can receive/send messages in the MC protocol control procedure. By using a separately sold
communication support tool (MX Component), a communication program for the host system can be created
without considering detailed protocols (communication procedures). (
