You can control MD series controller by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 0 ~ 99.
3) ADDRESS Write address. ( Refer to <Table 1> )
4) Extra1 Don't care.
5) Extra2 Don't care.
Write example 1)
PORT : 0, STATION:0, ADDRESS : 0323, Extra1 : , Extra2 :
The setting parameter shown above is a Enable of Alarm Output Control example for 0 station number of MD series controller.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 0 ~ 99.
3) ADDRESS Write address. ( Refer to <Table 1> )
4) Extra1 Output data format : 0 = interger, 1 ~ 4 = 1 ~ 4 decimal point.
5) Extra2 Don't care.
Write example 1)
PORT : 0, STATION:0, ADDRESS : 0221, Extra1 : 0, Extra2 :
The setting parameter shown above is an example of Input type changing for 0 station number of MD series controller.
