PCL-726 communication driver is the driver to communicate with input/output card of Advantech Co., Ltd. in Taiwan.
Note) PCL726 card must install at computer by ISA or PCI card type.
PCL726 card have 6 channel analog output, 16 channel digital input, 16 channel digital output.
<Figure 1> is read setting example of PCL726 communication driver.

Device part of <Figure 1> input 'None'.
In protocol option, you can set 'I/O memory address of PCL726 card'( 200 ~ 2F0 : can set by DIP switch ).
PCL726 communication driver’s read schedule
Read schedule of PCL726 communication driver input 'READ' one line.
Readed data of PCL726 communication driver save at 0 ~ 7 WORD memory such as follows :
0 ~ 5 : analog output 6 channel data (12 bit size : 0 ~ 4095),
6 : digital input 16 channel data,
7 : digital output 16 channel data.
You can control PCL726 output card 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 writing address in digital output = 0070 ~ 007F.
4) Extra1 don't care.
5) Extra2 don't care.
Write example 1)
PORT : 0 , STATION : 0, ADDRESS : 0073, EXTRA1 : , EXTRA2 :
The setting parameter shown above is digital control( On/Off ) example for 3 ( 4th ) address digital output.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION don't care.
3) ADDRESS writing address in analog output = 0000 ~ 0005.
4) Extra1 don't care.
5) Extra2 don't care.
Write example 1)
PORT : 0 , STATION : 0, ADDRESS : 0001, EXTRA1 : , EXTRA2 :
The setting parameter shown above is analog value setting( 0 ~ 4095 ) example to 1 ( 2nd ) address analog output.
