4.13.3 MC protocol communication

PERIPHERAL I/F of the Motion CPU enables communication using the
(Note-1)
MC protocol .
External devices such as personal computers and display devices read/write device
data from/to the Motion CPU using the MC protocol.
External devices monitor the operation of the Motion CPU, analyze data, and manage
production by reading/writing device data.
REMARK
(Note-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 "MELSEC-Q/L Communication
Protocol Reference Manual".
POINT
External devices such as personal computers and display devices can
communicate with only the Motion CPU connected by Ethernet using the MC
protocol.
An access to any of the following CPU modules is not available.
• CPU modules on other stations, via CC-Link or others.
