SAMSUNG FARA-N communication driver

SAMSUNG FARA-N Communication Driver is the driver to communicate with FARA-N PLC of SAMSUNG in Korea.

1. Read settings

<Figure 1> is read setting example of SAMSUNG FARA-N communication driver .

<Figure 1>  Read setting example of SAMSUNG FARA-N communication driver

Device Setting of <Figure 1> are input, Com Port(COM7), Com Speed(115200), Parity Bit(1), Data Bit(8), Stop Bit(1).

Also whether to use of new protocol(0 = do not use, 1 = use, default = 0) is set by using option part.

SAMSUNG FARA-N communication driver read schedule

Read schedule setting parameters are as follows:

1) STATION – PLC address1 ~ 63 or 238 = Loader Porter).

2) Read Command – read memory type or command. (Refer to <Table 1>)

3) Read Start Address – read start number of memory type.

4) Save Start Address for Communication Server – saveing start address of Communication Server.

5) Read Size – read wird size of word unit.

<Table 1> is a description of read commands type of SAMSUNG FARA-N communication driver.

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.

<Figure 2> Example of SAMSUNG FARA-N Communication Driver’s Option dialogue box

Whether to use of new protocol is set by using by using the part of 'Use New Protocol’ shown in <Figure 2>

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

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

2. Write settings

You can change the memory values of FARA-N PLC by using write settings.

Bit write 

Bit write setting parameters are as follows:

1)  PORT :  Port no. (0 ~ 255)

2)  STATION : PLC address(1 ~ 63 or 238).

3)  ADDRESS : write address of memory type.

4)  EXTRA 1 : write memory type = Y, R, L.

5)  EXTRA 2 : Don't care.

Write example 1)

PORT:0,  station:238, ADDRESS:0000, Extra1:Y  Extra2 :

The setting parameter shown above is an example of bit write for Y0000 memory of FARA-N PLC connected with 0 port, 238 PLC address.

Word write

Word write setting parameters are as follows:

1)  PORT : Port no. (0 ~ 255)

2)  STATION : PLC address(1 ~ 63 or 238).

3)  ADDRESS : write address of memory type.

4)    EXTRA 1 : write memory type = Y,R,L,DT,FL,Ld,IX,IY,ID,SV,EV, MD.xxy(Refer to <Table 2>), MC.y(Refer to <Table 2>)

5)    EXTRA 2 : 1 = When exceeding 9999 write address of DT, FL, Ld memory type.

             0 or other=  Don't care.

<Table 2> is a description of monitor data(MD) and monitor point(MC) write commands for SAMSUNG FARA-N communication driver.

Write example 1)

PORT:0, Station:238, Address:0010, Extra1:SV Extra2 : 0

The setting parameter shown above is an example of word write for S0010(timer/counter setting memory type) memory of FARA-N PLC connected with 0 port, 238 PLC address.

설정 예2)

PORT:0, Station:238, Address:0123, Extra1:DT, Extra2:1

The setting parameter shown above is an example of word write for D10123(Data Register) memory of FARA-N PLC connected with 0 port, 238 PLC address.

3. Connetction of serial cable

You have to connect serial communication cable in the following ways.

Connection of serial communication cable

You can connect  normal RS-232C  communication cable to FARA-N PLC and PC.
