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

Cyclic transmission stop and restart

This function is used to stop the cyclic transmission during debugging and other operations. (Data reception from other
stations and data sending from the own station are stopped.) Also, the stopped cyclic transmission is restarted. Transient
transmission does not stop.
Cyclic transmission is stopped and restarted using the link start/stop or the program of the MELSECNET diagnostics.

• Whether to stop/restart cyclic transmission by the stop/restart instruction of cyclic transmission is
determined for each station that received the instruction.
• When giving an instruction to restart cyclic transmission by specifying a station or target station that is
different from the station instructed to stop in such a case where the station instructed to stop cyclic
transmission goes down, perform forced link start.
• When link stop (all stations) is enabled, the link stop instruction (all stations) is always performed for all
stations. Therefore, cyclic transmission stops at the station connected to the network after the instruction is
given. Also, even if the instruction to restart cyclic transmission is given to an individual station (for forced
link start or other purposes), the station will remain stopped. When restarting cyclic transmission, perform
link startup (all stations) or forced link start (all stations).
