Issue:
I am running a reactor test where I record the in-cylinder temperature and pressure. Whenever I run tests I would get the error (65583) shown in the first picture at random.
I would also be asked to undeploy one of my modules when running the VI and discovered that it
was due to the info shown in the second picture. Could anyone tell me how to resolve this problem?
Solved! Go to Solution.

Did you notice that little horizontal line before the Error number? That is something called a "minus sign" (you can see it in the Error Message you pasted). Minus signs are important, especially when running "reactor tests".
Can you provide any information on what could be causing the "common-mode range error" (I'm not certain what that even means) in the Shared Variable ORC\Mod8\TC6? Do you have any code that involves this variable you would care to share with us? Maybe there's a missing "-" sign ...

Thank you for your reply. I am not sure what the "common-mode range error" was either. To further elaborate on the project. It is a small fully sealed vessel which will all research on various fluids under high temperature pressure conditions. It uses a melt pressure and in-built temperature sensor as well as a thermocouple as shown in the first picture below. It runs off a simple block diagram. I've been able to bypass the error message by adding the "Clear Error VI" into my block diagram as shown in the second picture but I am still interested in knowing the reason to that error.

The max. common mode voltage range ist the voltage between any channel and ground or, if not grounded, the voltage between any two channels. The max. common mode voltage is 1.2V
It's the biggest issue of such kind of hardware (not only the NI-9213).
Try to connect the ground (COM) and optimize the grounding of the complete system. If this is not possible or does not help, you might have a problem which cannot be solved with the NI-9213.

Thank you,
It seem that we were having problems with grounding. For intance, we found out that the CRio chassis was not properly grounded and one of our rigs. So full decommissioning and recommissioning of sensor and equipment wiring to NI modules is required.
