Network Test - Mitsubishi Electric MELSEC iQ-R Series User Manual

Network Test

This test stops/restarts cyclic transmission. This function is used when it is not desirable to receive data from another station
or to send own station data when starting up the system.
For stopping/restarting cyclic transmission, data communication (link refresh) between the CPU module and
the RJ71LP21-25 is not stopped or restarted. Use the program to stop/restart data communication (link
refresh).
