COMMUNICATION USING BUILT-IN ETHERNET

PORTS OF CPU MODULE

7.4 MC Protocol Communication

Built-in Ethernet ports of the Built-in Ethernet port QCPU enable communication using the

MC protocol

*1

.

External devices such as personal computers and display devices read/write device data
from/to the CPU module using the MC protocol.
External devices monitor the operation of the CPU module, analyze data, and manage
production by reading/writing device data.
Besides, the remote password function can prevent unauthorized access to the CPU
module from outside of the system. (

POINT

External devices such as personal computers and display devices can
communicate with only the connected CPU module using the MC protocol.
An access to any of the following CPU modules is not available.

• CPU modules on another station via network
• Other CPU modules in a multiple CPU system

* 1 : The MC protocol is an abbreviation for the MELSEC communication protocol.

The MELSEC communication protocol is a name of the communication method used to access
CPU modules from external devices in accordance with the communication procedure of Q series
programmable controllers (such as serial communication modules, Ethernet modules).
For details on the MC protocol, refer to the following manual.
