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.
DY600S DPM controller can set baud rate(2400, 4800, 9600, 19200, 38400), controller station number and dot position by using front panel's setting button.
DY600S DPM communication driver’s read schedule
DY600S DPM communication driver's read schedule input 'READ' one line( or blank ).
Read schedule example)
READ,
You can write the setting value by using write settings.
Bit Write
Bit write and word write have the same setting parameters except output value.( 0 or 1 )
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION DY600S DPM controller station number = 0 ~ 999.
3) ADDRESS Write data saving internal memory address of communication server.
4) Extra1 Controller type : 4 = 4 digit controller, default, 6 = 6 digit controller.
5) Extra2 Decimal point = 0 ~ 5.
0 : don't use decimal point,
1 ~ 5 : 1 ~ 5 digit decimal point.
Write example 1)
PORT : 0, STATION : 1, ADDRESS : 0020, EXTRA1 : , EXTRA2 : 1, Write value : 123.4
The setting parameter shown above is a number write example of 4 Digit DY600S DPM model with 1 decimal point and write value equal 123.4.(station number = 1)
After write, save writed data(123.4) to address 20 WORD, FLOAT, DWORD memory of communication server.
Write example 2)
PORT : 0, STATION : 2, ADDRESS : 0021, EXTRA1 : , EXTRA2 : 2, Write value : –1.23
The setting parameter shown above is a number write example of 4 Digit DY600S DPM model with 2 decimal point and write value equal –1.23.(station number = 2)
After write, save writed data(-1.23) to address 21 WORD, FLOAT, DWORD memory of communication server.
Write example 2)
PORT : 0, STATION : 3, ADDRESS : 0022, EXTRA1 : 6, EXTRA2 : 4, Write value : 45.6789
The setting parameter shown above is a number write example of 6 Digit DY600S DPM model with 4 decimal point and write value equal 45.6789.(station number = 3)
After write, save writed data(45.6789) to address 23 WORD, FLOAT, DWORD memory of communication server.
Connection of communication cable and main power line are as follows.
Connection of communication cable
Please connect R-(5th connector from left), R+(6th connector from left) connectot of DY600S DPM controller and T-, T+ RS-485 connector of computer such as below diagram.
DY600S DPM controller side Computer side( RS-485 connector )
5th connector from left ( R-) ------------------------- T-
6th connector from left ( R+) ------------------------- T+
Connection of main power line
Please connect 24 V DC main power to 1st( +24V ) and 2nd( 0 V ) connector from left.
<Figure 2> is main power line and communication connector of DY600S DPM controller.
