Link Start/Stop
This function stops the cyclic transmission during debugging and other operations. (Data reception from a slave station and
data sending from the own station are stopped.)
Also, the stopped cyclic transmission is 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, an error might occur in the slave station.
Cyclic transmission can be started and stopped using link special relay (SB) and link special register (SW).
