FL REMOTE COMMUNICATION FUNCTION
Cyclic transmission
4.7 Cyclic transmission
Cyclic transmission transmits data periodically. Each node shares data through common memory.
Data of I/O area is updated periodically by cyclic transmission.
The master controls the inverter by setting run command (control input command, set frequency, etc.) in the output
data area.
The inverter sets the inverter status (output frequency, output current, various signals, etc.) in the input data area and
sends it to the master.
