Ladder Operation
Operation is changed depending on the sequence No. When the PLC is started, the sequence No. 1 is set, and the station
No. command is changed as the following table (station No. 1). When the station No. response (station No. 2) and the station
No. response (station No. 3) match with the station No. command, the sequence No. increases by one. When the process up
to sequence No. 3 is complete, the number returns to 0.
