(Note 1) When sending command 15, set [S1] transfer method specification to word units (H0).(Note 2) Status change start number will be set to write target coil number. (destination unit)(Note 3) Change coil number will change write bit number to HEX.(Note 4) Due to MODBUS protocol limits, change coil number maximum is 2032 (07F0H).Data number (byte number) is calculated as 1 data (1 byte) for 8 coils.
