Link Start/Stop - Mitsubishi Electric MELSEC-Q Series User Manual

9.4 Link Start/Stop

This function stops or restarts cyclic transmission of the Simple Motion module. Data
reception from slave stations and data transmission of the own station are disabled during
debugging. The stopped cyclic transmission can be restarted.
This function does not stop or restart transient transmission.
This function can stop and restart the cyclic transmission of an asynchronous communication
device. It cannot stop or restart the cyclic transmission of a synchronous communication
device. When link start/stop is executed for the synchronous communication device and the
Simple Motion module, "Not support function execution error (error code: D300H)" occurs.
Also, when link start/stop is executed for the multiple stations including the asynchronous
communication devices and synchronous communication devices at the same time, only link
start/stop is executed for the asynchronous communication devices.
The operation for the synchronous communication devices is saved as history.
