NS370 4A/6A DPM (SAM JUNG) communication driver read schedule
NS370 4A/6A DPM (SAM JUNG) communication driver's read schedule input 'READ' one line or blank.
RS-485 communication cable between NS370 4A/6A DPM controller and computer is as follows :
You can write to NS370 DPM controller by using 'write settings'.
Digital Write
NS370 4A/6A DPM (SAM JUNG) communication driver don't support 'Digital Write'.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION 0 ~ 999 DPM controller address.
3) ADDRESS don't care.
4) Extra1 type of DPM.
6 : data writing command to 6 digit DPM controller,
4 : data writing command to 4 digit DPM controller,
BLANK6 : setting to all blank command of 6 digit DPM,
BLANK4 : setting to all blank command of 4 digit DPM,
SAVE6 : group( multi ) write setting command for data saving of 6 digit DPM,
SAVE4 : group( multi ) write setting command for data saving of 4 digit DPM,
WRITE : group ( multi ) write command from SAVE6 or SAVE4 command( saved data, maximum saving count = 20 )
space, ... : data writing command to 4 digit DPM controller.
5) Extra2 decimal point. ( decimal point of controller can set F1, F2 switch )
0 ~ 5 : 6 digit DPM controller,
0 ~ 3 : 4 digit DPM controller.
Write example 1)
PORT:0, station:1, ADDRESS:0000, Extra1: , Extra2 : 0
The setting parameter shown above is data writing example of 4 digit DPM controller with 0 decimal point. ( controller setting = 0 decimal point )
Write example 2)
PORT:0, station:2, ADDRESS:0000, Extra1: , Extra2 : 1
The setting parameter shown above is data writing example of 4 digit DPM controller with 1 decimal point. ( controller setting = 1 decimal point )
Write example 3)
PORT:0, station:3, ADDRESS:0000, Extra1: , Extra2 : 2
The setting parameter shown above is data writing example of 4 digit DPM controller with 2 decimal point. ( controller setting = 2 decimal point )
Write example 4)
PORT:0, station:4, ADDRESS:0000, Extra1: , Extra2 : 3
The setting parameter shown above is data writing example of 4 digit DPM controller with 3 decimal point. ( controller setting = 3 decimal point )
Write example 5)
PORT:0, station:5, ADDRESS:0000, Extra1: BLANK6, Extra2 : 0
The setting parameter shown above is all blank setting example of 6 digit DPM controller with 0 decimal point. ( controller setting = 0 decimal point )
Write example 6)
PORT:0, station:6, ADDRESS:0000, Extra1: 6, Extra2 : 4
The setting parameter shown above is data writing example of 6 digit DPM controller with 4 decimal point. ( controller setting = 4 decimal point )
Write example 7)
PORT:0, station:7, ADDRESS:0000, Extra1: 6, Extra2 : 1
The setting parameter shown above is data writing example of 6 digit DPM controller with 1 decimal point. ( controller setting = 1 decimal point )
Write example 8)
PORT:0, station:8, ADDRESS:0000, Extra1: 6, Extra2 : 0
The setting parameter shown above is data writing example of 6 digit DPM controller with 0 decimal point. ( controller setting = 0 decimal point )
Note) After writing, the writing data save at address of 'station' WORD, FLOAT, DWORD memory.
