Cyclic Transmission Stop And Restart - Mitsubishi Electric MELSEC-Q Series User Manual

8.3.7 Cyclic transmission stop and restart

During debugging and other operations, cyclic transmission is stopped. (Data reception from
a slave station and data sending from the own station are stopped.) Also, the stopped cyclic
transmission is restarted.
Transient transmission does not stop. (Refer to Section 9.4.)
The devices which can stop/restart cyclic transmission are the asynchronous communication
devices. The cyclic transmission with the synchronous communication devices cannot be
stopped/restarted.
