Analog Input Module Clarification

[RBPLC]

As shown in the attached image (specifically Analog Input 0 and Analog Input 1), what would be the use case for selecting 0-5VDC (as in Analog Input 0)? I'm assuming that this is done to increase the resolution of the input. As shown in the dialog, when selecting 0-5VDC, the Units/Ct displayed is 305 uV/Ct but is actually 152.5 uV/Ct when looking at the raw counts WX1. I suspect I'm not the only person to have fought this confusion. By selecting 0-5VDC, the counts are twice what they should be when monitoring WX1 implying that 152.5 uV/Ct is correct. Is the resolution being increased when halving the voltage range or is the resolution the same and the raw counts just being doubled behind the scene somewhere? Either way, the dialog box should clarify when switching between ranges.  If the resolution of the input isn't increased by halving the range the only benefit I can see in selecting 0-5VDC is that you get an out of range bit when going over 5VDC.

I believe the units/ct is wrong. The local channels are different than the modules, and I think that's a holdover from the local.

On local channels, 5V has a 16k range and 10V is 32k. The modules oversample to make both 5V and 10V 32k. The UI is common code and didn't get the change for the modules. Easy fix.

I see the issue. Someone tried to get clever, but wasn't clever enough. One guess as to who that was.

It might be worth checking the Analog Output Modules as well. They could possibly have the same issue? I don't remember.

Output was correct.
