Chapter 9 Mc Protocol Communications; Applications - Mitsubishi Electric MELSEC-L SERIES Basic User Manual

CHAPTER 9
Using MC protocol communications, connected devices that can send and receive data in accordance with the MC
protocol can access a CPU module. Because an E71 processes and sends/receives data based on commands from
connected devices, no programs for data communications are required on the programmable controller side.
For MC protocol communications, refer to the following.
MELSEC Communication Protocol Reference Manual
9.1

Applications

Applications of MC protocol communications are as follows.
(1) Data read/write
Data can be read/written from/to a CPU module device and intelligent function module buffer memory. This
allows a connected device to monitor the CPU module operation, perform data analysis, and manage production
control.
(2) File read/ write
Files such as a program and parameter stored in a CPU module can be read/written. This allows a connected
device to manage CPU module files and switch execution programs.
(3) Remote control of a CPU module
The remote operation allows a connected device to remotely operate a CPU module.
(4) Turning off the COM.ERR. LED
The COM.ERR. LED on an E71 can be turned off from a connected device.
(5) Remote password lock/unlock
A remote password can be locked/unlocked from a connected device.
(6) Access to a programmable controller in other stations over other networks
In a system containing CC-Link IE Controller Network, CC-Link IE Field Network, MELSECNET/H,
MELSECNET/10, and Ethernet, access to a programmable controller in other stations can be performed over
each network from a connected device.
