Device part of <Figure 1> input Com Port(COM1), Baud Rate(4800), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
DPM2 communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number.
2) Read Command – Command = DI, DO, AI, AO, CT...
3) Read Start Address – Read address of input or output card. According to setting switch of input or output card.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Read size = fixed according to input or output card. DI, DO = 1, AI, AO = 16, CT = 12.
Read schedule example)
READ, 0, DI, 0, 5, 4,
READ, 0, DI, 0, 6, 5,
READ, 0, AI, 0, 19, 10,
READ, 0, AI, 0, 20, 26,
READ, 0, AI, 0, 21, 42,
READ, 0, CT, 0, 23, 100,
You can write the setting value by using write settings.
DPM2 communication driver can write digital, analog output card and S-800S(MOSAIC INDICATOR) connected to DPM2 controller.
Bit Write
Bit write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION DPM CPU card number = 0 ~ 256.
3) ADDRESS Write card, channel address.
High 3 digit = card number,
Low 1 digit = channel number.
4) Extra1 Don't care.
5) Extra2 Don't care.
Write example 1)
PORT:0, STATION:1, ADDRESS:0100, Extra1 : , Extra2 : 0
The setting parameter shown above is a write(On/Off) example of 0 channel number(DO card), 10 card number of 1 CPU.
Word Write of AO, CNT card
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION DPM CPU card number = 0 ~ 256.
3) ADDRESS Write card address.
4) Extra1 Card type = AO, CNT.
5) Extra2 Channel value = 0 ~ 15.
Write example 1)
PORT:0, STATION:1, ADDRESS:2, Extra1:AO, Extra2:5
The setting parameter shown above is a write example of 5 channel number(AO), 2 card number of 1 CPU.
Word Write of S-800S Mosaic Indicator
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION DPM CPU card number = 0 ~ 256.
3) ADDRESS Write card address.
4) Extra1 Command = CMD, DISP.
5) Extra2 Command type when CMD write command.
1 : dot position change,
1 : Polarity change,
4 : address change.
Write example 1)
PORT:0, STATION:1, ADDRESS:2, Extra1:CMD, Extra2:1, Output value : 2
The setting parameter shown above is a write example of dot position change(changed dot position = 2).
Write example 2)
PORT:0, STATION:1, ADDRESS:2, Extra1:DISP, Extra2 : , Output value : 2
The setting parameter shown above is a write example to S-800S Mosaic Indicator, display value = 2, card address = 2, CPU number = 1.
