Read schedule example) 

READ,

 

2. Writing settings

You can write the setting value by using write settings.

 

Bit Write

DPM-NET 424C/624C communication driver don't support bit write.

 

Word Write

Word write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             DPM-NET controller station number = 0 ~ 255. ( Refer to <Table 1>, <Table 2> )

3)  ADDRESS           Don't care.

4)  Extra1                   Alarm status. ( DPM-50 model don't support alarm status )

H : HIGH ALARM status – blinking,

L : LOW ALARM status – blinking.

10 : Auto.

5)  Extra2                   Decimal point = 0 ~ 3 or 10.

0 : don't use decimal point,

1 : 1 digit decimal point,

2 : 2 digit decimal point,

3 : 3 digit decimal point,

10 : auto digit decimal point - according to writing number. ( max 3 digit decimal point )

3. Connection of communication line and controller's station setting

You have to connect RS-422 communication cable between DPM-424C, DPM-64C, DPM-50 controller and computer such as <Figure 2>. 

 

Note) When you use the 'Multi-Drop', please install 100 ヘ termination resistor at the end controller.
