HY-DAC Power Meter communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 0 ~ 255 controller station number.
2) Read data type – DI = digital input, DO = digital output, AI = analog input, AO = analog output, SYS = read of system status.
3) Read Start Address – Reading start address. DI, DO, AI, AO = 0 ~ 15, SYS = 0 ~ 31.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Read size. DI, DO, AI, AO = 1 ~ 16, SYS = 1.
6) Group number – DI, DO, AI = 0 ~ 3 group, AO = 0 group.
7) Single/Block selection – 0 = block, 1 = single(read size = always 1 ).

You can set HY-DAC Power Meter controller by using write settings.
Digital Write
Digital write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 0 ~ 255 station number of controller.
3) ADDRESS Writing address according to Extra1.
DO – 0 ~ 15,
SYS – 0 ~ 31,
RST, ON, OFF – don't care.
4) Extra1 Write command.
RST – reset command,
ON – On command,
OFF– Off command,
DO – digital output command,
SYS – setting of system status.
5) Extra2 Setting of 0 ~ 3 group number when 'DO' write command.
Write example 1)
PORT:0, station:49, ADDRESS:0002, Extra1:DO, Extra2 : 0
The setting parameter shown above is 1st( 0 ) group, 3rd( 2 ) digital output control(On/Off) example of 49 station HY-DAC controller.
Write example 2)
PORT:0, station:49, ADDRESS:0000, Extra1:RST, Extra2 :
The setting parameter shown above is reset command example of 49 station HY-DAC controller.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 0 ~ 255 station number of controller.
3) ADDRESS Writing address according to Extra1.
AO – 0 ~ 15,
SYS – 0 ~ 31,
RST, ON, OFF – don't care.
4) Extra1 Write command.
RST – reset command,
ON – On command,
OFF– Off command,
AO – analog output command,
SYS – setting of system status.
5) Extra2 Setting of 0 ~ 3 group number when 'AO' write command.
Write example 1)
PORT:0, station:49, ADDRESS:0005, Extra1:AO, Extra2 : 1
The setting parameter shown above is 2nd( 1 ) group, 6th( 5 ) analog output setting example of 49 station HY-DAC controller.
Write example 2)
