Device part of <Figure 1> input Device type(UDP/IP), IP address of PLC(192.168.10.20), service port of UDP/IP protocol ( 8000 ),respectively, according to setting of GP touch panel.
Also you can input enable of use of 'DWORD/FLOAT address x 2' (0 : don't use = word unit address, 1 : use = word unit address x 2, default = 1), 'IP address of computer'( example = 192.168.10.20), by using option part.
Note) IP address and other config of GP series touch panel can set GP touch panel.
GP Ethernet communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care. ( Fixed to 0 )
2) Read memory type – Memory type = W(default), W2, D, D2, F, F2. ( Refer to <Table 1> )
W = word Lo Hi, W2 = word Hi Lo, D = double word Lo Hi, D2 = double word Hi Lo, F = float Lo Hi, F2 = float Hi Lo.
3) Read start address – Read start address in memory.
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – Read size = max 3000 word.

You can set read schedule by using 
, 
, 
button and listbox
of <Figure 2>.
Also you can set use of DWORD/FLOAT address x 2 and IP address of computer at the part of ¡®DWORD/FLOAT Address x 2¡¯, ¡®Server(PC) IP Address¡¯ shown in <Figure 2>.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can set GP series touch panel by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care. ( Fixed to 0 )
3) ADDRESS Write address in memory.
Extra1 : X, X2, higher 3 ~ 7 digit = word unit decimal address, lower 1 digit = 0 ~ F bit position.
Extra1 : W, W2, D, D2, F, F2, word/double word/float unit decimal address.
4) Extra1 Write memory type = X(bit unit), X2(bit unit), W, W2, D, D2, F, F2.
5) Extra2 Don't care.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 031F, EXTRA1 : X, EXTRA2 : 0
The setting parameter shown above is a digital write(On/Off) example for 31 word, F bit address.
Write example 2)
PORT : 0 Station : 0, ADDRESS : 157A, EXTRA1 : X, EXTRA2 : 0
The setting parameter shown above is a digital write(On/Off) example for 157 word, A bit address.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care. ( Fixed to 0 )
3) ADDRESS Write address in memory.
Extra1 : X, X2, higher 3 ~ 7 digit = word unit decimal address, lower 1 digit = 0 ~ F bit position.
Extra1 : W, W2, D, D2, F, F2, word/double word/float unit decimal address.
4) Extra1 Write memory type = X(bit unit), X2(bit unit), W, W2, D, D2, F, F2.
5) Extra2 Don't care.
Write example 1)
PORT : 0 Station : 0, ADDRESS : 0000, EXTRA1 : W, EXTRA2 : 0
The setting parameter shown above is word write example for 0 word memory address.
Write example 2)
PORT : 0 Station : 0, ADDRESS : 0502, EXTRA1 : W, EXTRA2 : 0
The setting parameter shown above is word write example for 502 word memory address.
Write example 3)
PORT : 0 Station : 0, ADDRESS : 0120, EXTRA1 : D, EXTRA2 : 0
The setting parameter shown above is double word(Lo Hi order) write example for 120 double word memory address.( When you set 'use of DWORD/FLOAT address x 2', address = 240 word )
Write example 4)
PORT : 0 Station : 0, ADDRESS : 2150, EXTRA1 : F, EXTRA2 : 0
The setting parameter shown above is float word write example for 2150 double word(change standard float format) memory address.( When you set 'use of DWORD/FLOAT address x 2', address = 4300 word )
Write example 5)
PORT : 0 Station : 0, ADDRESS : 0005, EXTRA1 : D2, EXTRA2 : 0
