Device part of <Figure 1> input Com Port(COM1), Baud Rate(2400), Parity Bit(2), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Also you can set 'write after waiting time'( msec unit, 1 = 1/1000 second) by using option part.
DIESSEL Blending Controller communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number = 0 ~ 9.
2) Read Command – Don't care.
3) Read Start Address – Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1. ( Refer to <Table 1> )

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 Controller station number = 0 ~ 9.
3) ADDRESS Contents of setting value, 0 : clear count, 1 : ack dis, 2 : program no, 3 : step no, 4 : alcohol out, 5 : part of additive, 6 : alcohol in, 7 : preselection quantity,
4) Extra1 write command.
S : write setting data,
space or etc : saves the setting value to memory.
5) Extra2 Recipe number = 1 ~ 16.
Write example 1)
Station : 0, Address : 0000, Extra1 : S, Extra2: 1,
The setting parameter shown above is an example of write setting data of number 1 recipe.
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 0 ~ 9.
3) ADDRESS Contents of setting value, 0 : clear count, 1 : ack dis, 2 : program no, 3 : step no, 4 : alcohol out, 5 : part of additive, 6 : alcohol in, 7 : preselection quantity,
4) Extra1 write command.
S : write setting data,
space or etc : saves the setting value to memory.
5) Extra2 Recipe number = 1 ~ 16.
Write example 1)
Station: 1, Address: 0006 Extra1: , Extra2 : 1
The setting parameter shown above is an example of saves the setting to memory of 'alcohol in' value, number 1 recipe.
Write example 2)
Station: 1, Address: 0000 Extra1: S, Extra2 : 1
The setting parameter shown above is an example of write setting data of number 1 recipe.
