Device part of <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of controller.
One module of GANTNER controller consist one station. Also 1 channel of Analog or Digital is accounted one Word data.
GANTNER communication driver read schedule
Read schedule setting parameters are as follows:
1) STATION – Controller station number.
2) Read command – Don't care.
3) Read start address – Read channel start address.
4) Save Start Address for Communication Server – saveing start address of Communication Server.
5) Read Size – Word unit read size.
Read schedule example)
READ, 0, DI, 0, 0, 8,
READ, 1, DO, 0, 8, 8,
READ, 2, AI, 0, 16, 8,
READ, 3, AO, 0, 24, 8,
You can set the channel data by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number.
3) ADDRESS Write channel address.
4) Extra1 Don't care.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0003, Extra1: , Extra2 :
The setting parameter shown above is a digital(bit on/off) control example of 0(1st) word, 3(4th) bit, 1 controller station number.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number.
3) ADDRESS Write channel address.
4) Extra1 Don't care.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0002, Extra1: , Extra2 :
The setting parameter shown above is an analog write example of 2 word, 1 controller station number.
