DY-CPU Communication Driver

 

DY-CPU communication driver is the driver to communicate with electronic display board controller of Dongyoung in Korea.

 

1. Read settings

 

<Figure 1> is read setting example of  DY-CPU communication driver. 

<Figure 1>  Read setting example of  DY-CPU communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(fixed to 9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.

 

DY-CPU communication driver¡¯s read schedule

DY-CPU communication driver's read schedule input 'READ' one line( or blank ).

 

Read schedule example) 

READ,

 

2. Writing settings

You can write the setting value by using write settings.

 

Bit Write

Bit write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Don't care.

3)  ADDRESS           0000 ~ 9999 write address.(decimal unit)

4)  Extra1                   Write command.

E, F = ALARM, STOP,

blank, etc = RUN, STOP.

5)  Extra2                   Don't care.

 

Write example 1) 

Port:: 0,  Station : 0,  Address: 0000,  Extra1 :   ,  Extra2 :

The setting parameter shown above is a RUN/STOP control example of DY-CPU.(equipment address = 0)

 

Write example 2) 

Port:: 0,  Station : 0,  Address: 0002,  Extra1 : F ,  Extra2 :

The setting parameter shown above is a ALARM/STOP control example of DY-CPU.(equipment address = 2)

 

Word Write

Word write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Don't care.

3)  ADDRESS           0000 ~ 9999 write address.(decimal unit)

4)  Extra1                   Write command(blink status setting).

 E, e = ALARM,

blank, etc = normal status.

5)  Extra2                    Decimal point = 0 ~ 5.

0 : don't use decimal point,

1 ~3 : 1 ~ 3 digit decimal point.

 

Write example 1)  

Port:: 0,  Station : 0,  Address: 0000,  Extra1 :   ,  Extra2 : 1

The setting parameter shown above is a write example of DY-CPU with 1 decimal point.(equipment address = 0)

 

Write example 2)  

Port:: 0,  Station : 0,  Address: 0001,  Extra1 :  E,  Extra2 : 3

The setting parameter shown above is a write example of DY-CPU with 3 decimal point and 'ALARM' status.(equipment address = 1)
