PR4000 Series communication driver

PR4000 Series communication driver is the driver to communicate with PR 4000 Series controller of MKS Technology for productivity in Korea.

1. Read settings

<Figure 1> is read setting example of PR4000 Series communication driver.

<Figure 1> Read setting example of PR4000 Series 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.

 Baud rate, parity bit, data bit, stop bit of PR4000 Series controller can set by operation button of front panel.

Also you can set 'weather to use of RS-485 communication'( 0 = don't use, 1 = use, default : 0) by using option part.

PR4000 Series communication driver’s read schedule

Read schedule setting parameters are as follows:

1) STATION – 0 ~ 31 station number of controller when RS-485 communication mode.

2) Read command type – command = ?AC1, ?AC2, ?AV1, ?AV2, ST, .... ( refer to <Table 1> )

3) Read line/point number – line/point number when ?DP1, ?DP2 /  ?LN1, ?LN2 read command.

?DP1, ?DP2 read command : line number,

 ?LN1, ?LN2 read command : point number,

 other command  : don't care.

4) Save Start Address for Communication Server – Input save start address of communication server.

5) Read Size – fixed to 1. ( fixed to according to read command )

Read schedule example)

READ,     0,  ?AC1,     0,    0,   1,

READ,     0,  ?AC2,     0,    2,   1,

READ,     0,  ?AV1,     0,    4,   1,

READ,     0,  ?AV2,     0,    6,   1,

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

<Figure 2> Example of PR4000 Series communication driver’s Option dialog box

You can set read schedule by using , , button and listbox of <Figure 2>. 

Also, you can set weather to use of RS-485 communication by using the part of ‘Use RS-485 Communication' shown in <Figure 2>.

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

2. Write settings

You can control PR4000 Series 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             0 ~ 31 station number of controller when RS-485 communication mode.

3)  ADDRESS           don't care.

4) Extra1                    write command = SP1, SP2, .... ( refer to <Table 2> )

5) Extra2                    On/Off value or unit setting number.

 AC1, AC2 write command : On/Off value,

 RG1, RG2 write command : unit setting number,

other command : don't care.

<Table 2> is write command and contents for  PR4000 Series communication driver.

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1: SP1,  Extra2 :

The setting parameter shown above is write of setting value example for 1 channel, 1 station number PR4000 Series controller.

Write example 2)

PORT:0,  station:1, ADDRESS:0000, Extra1: RL1,  Extra2 :

The setting parameter shown above is write of relay value control( On/Off ) example for 1 channel, 1 station number PR4000 Series 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 220V AC to main power connector such as <Figure 4>.

4. Setting of baud rate, parity bit

PR4000 Series controller can set baud rate, parity bit, ... by using setting button of front panel. ( refer to <Figure 5> )

1. Please enter to 'Setup' menu by pressing 'Up', 'Down' at the same time.

2. Press 'ENTER' button after selecting the 'Setup' menu by 'Left', Right' button.

3. Select 'BAUDRATE' menu by 'Up', 'Down' button.

4. Select baud rate by 'Left', 'Light' button.

5. Press 'Up', 'Down' button after selecting the baud rate.

6. Press 'ENTER' button. Then will be completed the baud rate setting.

7. Also you can set 'parity bit', ... the same way as above.
