GE Ethernet communication driver is the driver to communicate(ethernet) with PLC of GE Fanuc Automation in U.S.A.
<Figure 1> is read setting example of GE Ethernet communication driver.
<Figure 1> Read setting example of GE Ethernet communication driver |
Device part of <Figure 1> input Device type(TCP/IP), IP address of PLC(192.168.1.101), service port of TCP/IP protocol (fixed to 18245 ),respectively, according to setting of PLC.
Also you can set 'readed data saving method for Bit memory'( BIT : decimal unit, 0, blank, etc : hexadecimal unit, default = 0), PLC model( 0 - 9000 series, PAC - PAC System, default = 0), Ethernet slot position for PAC System( 0 - 15, default = 1), whether to use 'address - 1' when Digital write( 0 - use, NB_ADDR - don't use,default = 0), whether to use 'address - 1' when Analog write( 0 - use, NW_ADDR - don't use,default = 0) by using option part.
GE Ehternet communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Don't care.
2) Read command – Memory type of PLC = R, RF, AI, AQ, I, Q, T, M, SA, SB, SC, S, G. ( refer to <Table 1> )
3) Read start addresst – Read start address of PLC memory.
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – Read size. ( 1 ~ 450 )
Read schedule example)
READ, 0, R, 0, 0, 50,
READ, 0, G, 0, 50, 50,
READ, 0, M, 0, 100, 10,

You can set read schedule by using , , button and listbox of <Figure 2>.
Readed data saving method for Bit memory, PLC model, Ethernet slot position for PAC System, whether to use 'address - 1' when Digital write, whether to use 'address - 1' when Analog write can set by using of Protocol Option part in <Figure 2>.
<Figure 3> Example of GE Ehternet communication driver¡¯s read schedule Add/Edit dialog box |
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 value of device memory by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Write addres in memory type.
when using 'address - 1' for Digital write at option : Address - 1,
when don't using 'address - 1' for Digital write at option : Address.
4) Extra1 Write memory type = I, Q, T, M, SA, SB, SC, G.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:0, ADDRESS:0001, Extra1: Q, Extra2 :
The setting parameter shown above is a bit write(On/Off) example of 0001(1st bit address) in the Q device memory.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Write addres in memory type.
when using 'address - 1' for Analog write at option : Address - 1,
when don't using 'address - 1' for Analog write at option : Address.
4) Extra1 Write memory type = R, RF, AI, AQ, I, Q, T, M, SA, SB, SC, G.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:0, ADDRESS:0005, Extra1: R, Extra2 :
The setting parameter shown above is an analog write example of 0005(5th word address) word in the R device memory.
