• Setting necessary parameters for communication
Communication related parameters must be set for PLC communication. parameters
n151 to n157 cannot be set during communication. Always set them prior to
performing communication.

n153 Slave address
n154 Baud rate selection
n155 Parity selection
n156 Sending waiting time
n157 RTS control
* The slave does not respond to the command from the master when set to 0.
Monitoring run status from the PLC, setting/referencing of parameters, fault reset and
multi-function input reference can be done regardless of run command or frequency
reference selection.
Multi-function input reference from PLC becomes OR with input commands from S1
to S7 multi-function input terminals.
