Processing details
This instruction executes multiple commands of an inverter connected to the communication channel (n) whose station
number is specified in (s1). Specify the send/receive data type using (s2), the head device which stores data to be written to
the inverter using (s3), and the head device which stores values to be read from the inverter using (d1). For details, refer to
MELSEC iQ-F FX5 User's Manual (Serial Communication).
