1) Stopping/restarting the cyclic transmission stops or restarts the data
receiving (link scan) between the network modules of the applicable
station. However, the data receiving (link refresh) between the
programmable controller CPU and master modules cannot be stopped
or restarted by this processing.
2) Execution using GX Developer
Through the network test, link startup, link stop and forced link startup
can be performed using GX Developer. For details on the network
testing methods, refer to the GX Developer Operating Manual.
