Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively according to setting of controller.
Also you can set 'weather to calculate and save the readed data to Float'( 0 = don't calculate, 1 = calculate, default : 0) by using option part.
Station number and baud rate, ... can set by write setting or button of front panel.
PDTech PQM communication driver¡¯s read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 255 station number of PQM controller.
2) Read command – command = DATA, VHD, SET, SAG. ( refer to <Table 1> ~ <Table 6> )
DATA – read of measurement data,
VHD – read of VHD measurement data,
SET – read of setting value,
SAG – read of Sag, Swell data.
3) Read start address – don't care.
4) Save Start Address for Communication Server – readed data saving start address of communication server.
5) Read Size – fixed to according to read command.

PSDTech PQM communication driver store the same data in WORD, DWORD, FLOAT( when using 'weather to calculate and save the readed data to Float' option ) memory, but the data format are different.
If you click the icon 
in protocol option part, you
can see the dialog box such as <Figure 2>. you can also set read schedule by
using this part.

When you click Add button or Edit button in dialog box of <Figure 2>, dialog box of <Figure 3> is shown.
You can control PQM 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 PQM controller.
3) ADDRESS type selection of PC, CT ration when PC, TC write command.
0 = PT 1, CT 1 ratio setting,
1 = PT 1, CT 1 index setting,
2 = PT 2, CT 2 ratio setting,
3 = PT 2, CT 2 index setting.
4) Extra1 write command = PT, CT, TIME, ID, RESET, MODE, TRANS, ...
PT, CT : PT, CT ratio/ index setting,
TIME : time syncronization with computer,
ID : station ID number setting of PQM controller,
RESET : clear command for 3 phase amount of active power( Kwh ), 3 phase amount of reactive power( Kvarh ) Clear,
( output value - 1 = 3 phase amount of active power clear, 2 = 3 phase amount of active power clear clear )
MODE : setting of wiring method, ( output value - 1= DA - 3P3W, 2 = 3P4W, 3 = 1P2W, 4 = 1P3W )
TRANS : selection of transformer type.
( output value - 1 = Dry 1MVA below, 2 = Dry 1MVA excess, 3 = Oil-Filled 2.5MVA below, 4 = Oil-Filled 2.5MVA excess 5MVA below, 5 = Oil-Filled 5MVA excess )
5) Extra2 don't care.
