| <Figure 1> Read setting example of LG GH1000 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 controller.
Note) You have to set 1 the parameter of communication execution. ( refer to GH1000 manual for more information )
LG GH1000 communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 1 ~ 16 controller station number.
2) Read command – File number = 1, 2, 3, 4, 5, 6, 7, 8. ( refer to <Table 1> ~ <Table 8> )
3) Read start address – read start address of file.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – read size.
Read schedule example)
READ, 1, 3, 7, 0, 1,
READ, 1, 8, 1, 1, 1,
READ, 1, 3, 10, 2, 1,
You can control LG GH1000 controller by using 'writing settings'.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 1 ~ 16 controller station number.
3) ADDRESS writing address of file.
4) Extra1 Write file number = 1, 2, 3, ....
5) Extra2 don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0010, Extra1: 3, Extra2 : 0
The setting parameter shown above is Manual MV(0:BUMPLESS, 1:PRESET) control example of 1 station LG GH1000 controller.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 1 ~ 16 controller station number.
3) ADDRESS writing address of file.
4) Extra1 Write file number = 1, 2, 3, ....
5) Extra2 don't care.
