SAMSUNG FARA-N PLUS Series communication driver

SAMSUNG FARA-N PLUS Series(for 700, 7000 series or NX70 Series model) Communication Driver is the driver to communicate with FARA-N PLUS PLC of SAMSUNG in Korea.

Compatible model of SAMSUNG FARA-N PLUS Series communication driver = SPC10, N70plus, N700plus, NX7, NX70(CPU70p1, CPU70p2), NX700(CPU700p) PLC model or compatible. 

Note) When you use FARA-N Alpha series, you use DLL-SAMSUNG FARA-N communication driver.

1. Read settings

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

<Figure 1>  Read setting example of  SAMSUNG FARA-N PLUS 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 PLC's Dip switch.

Input address and output address of FARA-N PLUS Series PLC are specified by mounting order of Input/Output card.(from left to write, R0000, R0001, ....)

Baud rate(9600 BPS, 4800 BPS, 2400 BPS, 1200 BPS,...) or other communication parameters can set by Dip switch of FARA-N PLUS PLC such as <Table 2>.

SAMSUNG FARA-N PLUS Series communication driver read schedule

Read schedule setting parameters are as follows:

1) STATION – PLC station address.

255 = 1 : 1 communication.

When RS-485 communication = 0 ~ 191.

2) Read Command – read memory type or command = R, L, M. K, F, TC, W, SV, PV, SR. (Refer to <Table 1>)

SV, PV, SR = read command of W memory type.

3) Read Start Address – read start number of memory type. (Refer to <Table 1>)

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

5) Read Size – read wird size of word unit = 1 ~ 128.

Read schedule example)

READ,  255,     R,     0,    0,  10,

READ,  255,     L,     0,   10,  10,

READ,  255,     M,     0,   20,  10,

READ,  255,     K,     0,   30,  10,

READ,  255,     F,     0,   40,  10,

READ,  255,     W,     0,   50, 128,

Digital input/output card of FARA-N PLUS PLC consists of  1 word per 16 channel, but analog input card have 2 word data that real data and channel value.

So you can't read all of the analog input card data at default R memory area.

Note) When you want read the data of each analog input card, you should be creat moving data routine from each specified memory to W, M or other memory area at PLC LADDER program

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 PLUS Series communication driver’s Option dialogue box

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

<Figure 3> Example of  SAMSUNG FARA-N PLUS Series communication driver’s read schedule Add/Edit dialogue box

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

<Table 1> is memory type and address range of FARA-N PLUS Series PLC.

2. Write settings

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

Digital Write

Digital write setting parameters are as follows:

1)  PORT                     Port no. (0 ~ 255)

2)  STATION               PLC station address = 0~191 or 255.

3)  ADDRESS             Write address of memory area. ( Refer to <Table 1>)

Higher 3 digit = decimal word unit address of  memory type.

lower 1 digit = 0 ~ F, hex-decimal bit position.

4) Extra1                    Memory area for writing =  only R, L, M, K, F memory.

5) Extra2                     Don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:012A, Extra1:M  Extra2 :

The setting parameter shown above is an example of bit write for M memory, 12(13th) word, A(11th) bit of FARA-N PLUS PLC connected with 0 port, 1 PLC station address.

Write example 2)

PORT:0,  station:1, ADDRESS:1275, Extra1:R  Extra2 :

The setting parameter shown above is an example of bit write for R memory, 127(128th) word, 5(6th) bit of FARA-N PLUS PLC connected with 0 port, 1 PLC station address.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                     Port no. (0 ~ 255)

2)  STATION               PLC station address = 0~191 or 255.

3)  ADDRESS            Write decimal word unit address of memory area. ( Refer to <Table 1>)

4) Extra1                    Memory area for writing =  R, L, M, K, F, W, TS, TC, S memory.

5) Extra2                     Don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:0036 Extra1:M  Extra2 :

The setting parameter shown above is an example of word write for M memory, 36(37th) word of FARA-N PLUS PLC connected with 0 port, 1 PLC station address.

Write example 2)

PORT:0,  station:1, ADDRESS:2047, Extra1:W  Extra2 :

The setting parameter shown above is an example of bit write for W memory, 2047(2048th) word of FARA-N PLUS PLC connected with 0 port, 1 PLC station address.

Note) You can read and write by using 'Absolute address' based on the 'R' memory.  ( Refer to 'Absolute address' of <Table 1>)

Example ) M0000 = R0192,

       W0000 = R0512.
