Device Setting of <Figure 1> are input, device type(TCP/IP), IP address of PLC(192.168.1.87), service port address(1000).
Also PLC address(1 ~ 63 or 238, default = 1), PC address(1 ~ 63 or 238, default = 2), whether to use of new protocol(0 = do not use, 1 = use, default = 0) are set by using option part (separated by commas each parameter).
SAMSUNG FARA-N Ethernet communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – PLC address1 ~ 63 or 238).
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.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can change the memory values of FARA-N PLC by using write commands.
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 Ethernet communication driver.
| Monitor Register Write Command Type | Content | Remark |
| MD.xx | Monitor Data(Word) Register | xx = DT, FL, Ld, IX, IY, SV, EV, WX, WY, WR, WL |
| MD.CL | Reset of Monitor Data Register | |
| MC.y | Monitor Point(Bit) Register | y = X, Y, R, L, T, C |
| MC.CL | Reset of Monitor Point Register | |

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.
You can set ethernet of FARA-N PLC by using 'Ethernet Configurator' program.
