DM430E rheostat input

[AlexeyZverev]

Hello ladies and gentlemen,

I've got an issue with connecting the temperature sensor to the DM430E (version DM430E-0-0-0-0, just in case). I have it connected to the input 10. I don't understand why, but I can't upload the screenshot (it tells "file is too big" or something similar), that's why the configuration of that input is there:
PinConfig0 = 1
PinConfig1 = 4
DigInConfigHigh = 3000
DigInConfigLow = 2000
FreqConfig = 0

The issue is that instead of having the resistance in Ohm line I get 0xFFFF, which is "signal not valid". The resistance measured by Ohm meter is around 3500, which is definitely inside of the supported range.

And also no matter what configuration I specify for PinConfig0 and PinConfig1 I get 0xFFFF on all lines (Ohm, Volt, Amp) except for the PinConfig0=1 and PinConfig1=0. In this case I get voltage value around 870.

So, the question is: what am I doing wrong, and how to make the temperature being read by the OI?

Thanks,
Alexey.

Have you wired your rheostat to ground/earth/0Vdc ?

Check out page 10 of the Input Configurations for PLUS+1® Controllers Technical Information Manual

The rheostat is wired to the the 0 VDC.

As of the reference to the manual... It tells "This type of input can only be read by a temperature/rheostat PLUS+1 input type." - the input 10 of the DM430E is a Multifunctional Dig/Ana/Freq/Resis/Curr input. Does this mean that this input cannot be used for a temperature sensor, even having in mind that the Resistor input is one of the possible ways the input works, and also on the page in the PLUS+1 for the PinConfig=4 the note states "4 = 0 - 10000 ohm (temperature/ rheostat mode)"? Or do I misunderstand something?

The issue was fixed by changing the FreqConfig to 1 having PinConfig0=1 and PinConfig1=4.
