2. Writing settings

You can write the setting value by using write settings.

Digital Write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Don't care.

3)  ADDRESS           Address of write = 0000 ~ 1600.

4)  Extra1                   Don't care.

5)  Extra2                   Don't care.

Write example 1) 

Port : 0,  Station : 0,  Address : 0000,  EXTRA1 : ,  EXTRA2 : 

The setting parameter shown above is a control(On/Off) example of 1st electric display address. 

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Don't care.

3)  ADDRESS           Address of write = 0000 ~ 0999.

4)  Extra1                   Decimal point of protocol = 0 ~ 3.

5)  Extra2                   Decimal point of software = 0 ~ 3.

Write example 1) 

Port : 0,  Station : 0,  Address : 0000,  EXTRA1 : 1,  EXTRA2 : 

The setting parameter shown above is a write example of 1st analog display with 1 decimal point.
