P-300 Temperature Controller communication driver

P-300 Temperature Controller communication driver is the driver to communicate with temperature controller of Digital Korea CO., LTD. in Korea.

1. Read settings

<Figure 1> is read setting example of  P-300 Temperature Controller communication driver. 

<Figure 1>  Read setting example of  P-300 Temperature Controller 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.

P-300 Temperature Controller communication driver’s read schedule 

Read schedule setting parameters are as follows:

1) Station – Controller station number = 1 ~ 31.

2) Read Command – Command = D, E, M, H, I, J. ( refer to <Table 1> )

D : read of R phase temperature and LED status, external status,

E : read of S, T phase temperature,

M : read of Peak value,

H : read of Warning & Fault setting,

I : read of Fan ON/OFF setting,

J : read of analog output setting.

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,     1,     D,     0,    0,   1,

READ,     1,     E,     0,    5,   1,

READ,     1,     M,     0,    7,   1,

READ,     1,     H,     0,    9,   1,

READ,     1,     I,     0,    11,   1,

READ,     1,     J,     0,   13,   1,

<Table 1> is read command and contents of P-300 Temperature Controller communication driver.

 <Table 2> is bit position and contents for LED status.

If you click the icon  in protocol option part, you can see the dialogue box such as <Figure 2>. you can also set read schedule by using this part.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

2. Writing settings

You can set  P-300 Temperature controller by using write settings.

Digital Write

Digital write and analog write have the same setting parameters except output value.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             controller station number = 1 ~ 31.

3)  ADDRESS           selection of output type.

 W write command : 0 = Warning setting, 1 = Fault setting,

 C write command : 0 = alarm Clear, 1 = error Clear, 2 = Peak High Clear, 3 = Peak Low Clear. 

4)  Extra1                   write command = W, C.

W : Warning & Fault setting, (output value = real value ⅹ 100)

C : Memory Clear command. 

5)  Extra2                   Don't care.

Write example 1) 

PORT : 0 , STATION : 1,  ADDRESS : 0000,  EXTRA1 : W,  EXTRA2 :

The setting parameter shown above is Warning setting example of station 1, P-300 Temperature controller.

 output value = real value ⅹ 100,  

example) setting value : 110, output value = 11,000

Write example 2) 

PORT : 0 , STATION : 1,  ADDRESS : 0001,  EXTRA1 : W,  EXTRA2 :

The setting parameter shown above is Fault setting example of station 1, P-300 Temperature controller.

Write example 3) 

PORT : 0 , STATION : 1,  ADDRESS : 0001,  EXTRA1 : C,  EXTRA2 :

The setting parameter shown above is error Clear example of station 1, P-300 Temperature controller.

Write example 4) 

PORT : 0 , STATION : 1,  ADDRESS : 0003,  EXTRA1 : C,  EXTRA2 :

The setting parameter shown above is Peak Low Clear example of station 1, P-300 Temperature controller.

3. Connection of main power and communication cable

Connection of main power and communication cable are as follows.

 Connection of main power

Please connect 65 ~ 265 V AC main power to 12, 13 connector such as <Figure 4>.

4. Setting of station number

You can set station number of P-300 Temperature controller by using front panet's operation button.

 1) Press ‘FUNC' button 5 times at 'normal' status. Then will be displayed  ‘d.01’ ( 01 = current setting settion) at display screen.

 2) Select station number by using 'Up', 'Down' button and press ‘FUNC’ button.

3) Return 'normal' status by pressing ‘EXIT/BZ STOP’ button.
