| <Figure 1> Read setting example of Dupline G3890 communication driver |
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.
G3890 controller can change baud rate(9600, 19200) by using Dip switch.
G3890 0030 model can set baud rate (1200, 2400, 4800, 9600) by using front panel button.
Note) Dupline controller have two communication method, Optolink(communication module) and G3890.
You have to set 'pc_c' mode In order to communicate with computer.
Dupline G3890 communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Don't care.
2) Memory Type – Memory = DT, DO, AC, AE, AO...
3) Read Start Address – Read data type = 0 - Byte, 1 - Word, 2 - Double Word.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1. ( read always 16 data )
Read schedule example)
READ, 0, DT, 0, 0, 16,
READ, 0, DO, 0, 16, 16,
READ, 0, AC, 0, 32, 16,
READ, 0, AE, 0, 48, 16,
READ, 0, AG, 0, 64, 16,
READ, 0, AI, 0, 80, 16,
READ, 0, AK, 0, 96, 16,
READ, 0, AM, 0, 114, 16,
READ, 0, AO, 0, 128, 16,
You can write the setting value by using write settings.
Bit Write
Bit write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS 0 ~ 7 write channel number.
4) Extra1 Write area = A, B, C ... P.
5) Extra2 Don't care.
Write example 1)
PORT : 0, STATION : 0, ADDRESS : 0002, EXTRA1 : H , EXTRA2 :
The setting parameter shown above is On/Off control example of 2 channel of 'H' area( H3 address ).
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Don't care.
4) Extra1 Write area = A, B, C ... P.
5) Extra2 Don't care.
Write example 1)
PORT : 0, STATION : 0, ADDRESS : 0002, EXTRA1 : K, EXTRA2 :
The setting parameter shown above is an example of KH' area control.
1) Read cycle and write cycle of Dupline G3890 communication driver should be set to more than 3000 mSec. Because of Dupline G3890 controller's response time equal more than 2000 mSce.
2) The case of the G3890 0030 model, You have to set 'pc_c' mode In order to communicate with computer. ( by using front panel button)
