If you set as above and writing OFF digital value, you can delete the group data of SNCU-2A no.0 LCU device connected with no.0 port. ( Deleting the data such as PSW, schedule and etc, can be done by analog output(Output value = 0 ~ 4) )

 

Write example 10)

PORT : 0   STATION : 5   ADDRESS : 0000  EXTRA1 : T_SET  EXTRA2 : 0

If you set as above and writing OFF digital value, you can set total LCU amount of SNCU-2A no.0 LCU device connected with no.0 port, as 5.

 

Analog Write

Set the analog write setting by using same method with digital write, but the output value is different.
