[sensitivity problem]

i solved the two problem

 

i want to take data from aquis 500 cr transmitter to the unitronics then i can export the data to excel

 

now i am struggling to linearize the MI 1 value as seen in the code

 

it seems that the sample linearization code doesnt work

 

my read values from the MI 1(4-20mA) and desired values are listed (left MI 1- right desired):

 

what function or mathematical calculation should i use for MI 1 in order to obtain the desired value ? 

 

 

485(mA) - 6.81(mikrosiemens/cm)

 

484 - 6.80

 

624 - 10.2

 

615 - 10.0

 

612 - 9.90

 

606 - 9.76

 

600 - 9.61

 

550 - 8.40

 

483 - 6.76

 

480 - 6.70

 

 

(i connect the -/ + terminals of analog output aquis 500 cr(transmitter) to the COMMON/AN 1 terminal of unitronic jz 20 r 16 )

 

[sensitivity problem]

i realized that my linearization code doesnt work for this issue

 

i read 445 mA as an input(MI 1) but it couldnt be converted to MI 11 

 

SI 84 value isnt changing (0) and SI 85 is always 20.

 

how can i see the changing of the MI 11 value ?

 

(i attached the screenshot of my linearization code )

Thanks for your suggestions i did it

[sensitivity problem]

Hi 

 

i m taking two voltage analog input and linearize them so i can read tempreature and purity value 

 

But the two value dont have enough sensitivity , input voltage is changing between the rate of  0-1 volt but the real engineering unit is 23.45 Celcius

 

how can i fix this issue ?

 

(i use the sample linearize program of the unitronics U90 software)

[reading analog input]

thanks for your suggestions

 

I link AI 0(analog input ) to MI 0(memory integer)  in hardware configuration tab

 

but when i go to ladder diagram and select input terminal i couldnt see MI addressing 

 

what function should i use in ladder diagram and i can see the input results on display screen ?

 

( i made analog input wiring according to current , is there any incoordination with sensor (SICK DT35) characteristic ? )

[reading analog input]

Hi i want to read analog input from my distance measuring sensor (SICK DT35) then i want to scale and see the data(milimeter) in the Jz20  r16 plc screen.

i made three wiring :

1.sensor "supply voltage" goes to PLC "V+" terminal 

2.sensor "0 V" goes to PLC "0V"

3.sensor "switiching output" goes to "AN0" terminal of the PLC

 

i can communicate on COM port 10 of my PC to PLC and i can download and upload the  program.

 

İ dont know how to write code and how to make addressing with hardware and software input terminal in U90 

 

Can you help me
