Ucmm Message Communications (Client) - Mitsubishi Electric MELSEC iQ-R Series User Manual

UCMM message communications (client)

Without establishing a connection between the CC-Link IE TSN Plus module and the external device (server), message
communications are performed at any timing.
Once per request, communications are performed with the external device without opening a connection.
The set command request is sent to the external device set in the request area of the 'Class3/UCMM communication area'
(Un\G7751680 to Un\G8275967) in the CC-Link IE TSN Plus module. The command response from the external device is
stored in the response area of 'Class3/UCMM communication area' (Un\G7751680 to Un\G8275967).
