Chapter 5 Mc Protocol Communication - Mitsubishi MELSEC L Series User Manual

CHAPTER 5
The built-in Ethernet port allows MC protocol communication. From an peripheral 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. (
107, CHAPTER 9)
From the peripheral device such as a personal computer or HMI, only the CPU module connected can communicate using
MC protocol.
An access to a CPU on another station via CC-Link network is not allowed.
To start MC protocol communication, perform the following steps.
Connecting cables and external devices
Setting parameters
Writing to the CPU module
For the MC protocol communication, refer to the following manual.
MELSEC-Q/L MELSEC Communication Protocol Reference Manual
Remark
Access through routers is also available. When configuring the settings for it, set the subnet mask pattern and default router
IP address. (
