Chapter 5 Mc Protocol Communication; Sending A Command From An External Device To The Cpu Module - Mitsubishi L02CPU User Manual

CHAPTER 5
The built-in Ethernet port allows MC protocol communication.
5.1
Sending a Command from an External Device to the CPU
Module
From an external device such as a personal computer or HMI, device data of the CPU module can be read or written
using MC protocol. Monitoring of CPU module operation, data analysis, and production control are available on a
personal computer or HMI by these device data reading and writing. Besides, the remote password function can
prevent unauthorized access from outside of the system. (
From the external device such as a personal computer or HMI, only the CPU module connected can communicate using MC
protocol.
An access to a CPU module on another station via CC-Link network is not allowed.
To start MC protocol communication, perform the following steps.
Connecting cables and external
devices
For the MC protocol communication, refer to the following manual.
