starts communication with the following settings:
Communication parameter settings:
Module type
Status display/control register
Communication response wait time
Cyclic communication retry count:
Remote station IP address
Endian conversion
Local station transmission area 1
Set all parameters other than indicated above to "0".
Ladder program example:
S012: System register that performs a one-sequence cycle ON
operation when the ladder status changes from STOP to RUN.
