[m91-2-ua2 Temperature in ladder diagram]

I think I got it. Se attached files.

But how can I get a warning if the temperature is under 10 degrees celcius? And a warning if it's over 40 degrees celcius?

[m91-2-ua2 Temperature in ladder diagram]

Hello

I am working with my unitronics m91-2-ua2 PLC.  I have a problem with getting correct temperature from my temperature sensor, type J.

The jumpers in the PLC are moved to  thermocouple input, I am using universal input no. 1.

How do i get feedback in my ladder diagram? Which symbols should I use to get a range fro -40 Celcius to 200Celcius?

[Programing analog I/O]

This is my program. I still have a problem with the low readings. 

When it's 4mA on the analog input, it shows 9,6mA on the analog output.

When it's 20mA on input, its 19,8mA on output.

 

[Programing analog I/O]

Hello

I just bought a Unitronics M91-2-UA2 PLC.

I am trying to program the analog I/O, but I cant get them to talk together.

I have a loop calibrator on the analog input 4-20ma.

On the analog output i have a multimeter that i can recieve 4-20ma. 

The problem is when i give the input 4ma, the output showa 16ma. When I adjust the input to 8ma, the output shows 12ma... 

Can anyone help me with the ladder diagram to get the output to communicate with the input.
