DCU-100C Communication Driver

 

DCU-100C Communication Driver is the driver to communicate with power control equipment of Shinyoung ENT.in Korea.

 

1. Read settings

 

<Figure 1> is read setting example of  DCU-100C communication driver.

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

 

DCU-100C communication driver¡¯s read schedule 

Read schedule setting parameters are as follows:

1) Station – DCU station number = 0 ~ 15.

2) Read Command – Don't care.

3) Read Start Address Don't care.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – fixed to 1. ( Refer to <Table 1> )

 

Read schedule example) 

READ,     0,      ,     0,    0,   1,

READ,     1,      ,     0,   30,   1,

 

<Table 1> is store values and contents of DCU-100C communication driver.

Store Values Contents  Data Range Remarks
Start Add + 0 ~ 3
or 0 ~ 7
16 or 32 DI status value  4 DI value( 0 ~ 15 ) at each address the numbers of DI = differ from according to controller type
Start Add + 5 ~ 19
or 8 ~ 23
16 AI current value 0 ~ 4095 ( 12 bits )  
Start Add + 20 ~ 23
or 23 ~ 27
4 PI current value 0 ~ 65535 ( 16 bits ) When using PI
<Table 1> Stored values and contents of DCU-100C communication driver

 DCU-100C communication driver store the same data in WORD, DWORD, FLOAT memory, but the data format are different. 

 

2. Writing settings

You can control of DO by using write settings.

  

Bit Write

Bit write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             DCU station number = 0 ~ 15.

3)  ADDRESS           Relay number.

4)  Extra1                   Write command = CLEAR - command of PI board clear,  DO or space - control of DO.

5)  Extra2                   Don't care.

 

Write example 1)

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

The setting parameter shown above is an example of 0(1st) DO control(On/Off) of 0 DCU-100C controller address.

 

Write example 2)

PORT : 0   STATION : 0   ADDRESS : 0005  EXTRA1 :  EXTRA2 : 0

The setting parameter shown above is an example of 5(6th) DO control(On/Off) of 0 DCU-100C controller address.

 

Write example 3)

PORT : 0   STATION : 0   ADDRESS : 0000  EXTRA1 : CLEAR  EXTRA2 : 0

The setting parameter shown above is an example of PI board clear command of 0 DCU-100C controller address.

 

Word Write

Word write and bit write have the same setting parameters except output value.

 

3. Connection of communication cable

You have to connect normal RS-232C or RS-485 communication cable at RS-232C or RS-485 connector of DCU-100C controller.
