AI563 does not read input
I am wondering if I need to configure anything else? I think I have all the scaling figured out I just can't seem to get any input signal. I have my positive wire connected to I0+ and my negative wire connected to I0-
I understand that this module only accepts -80mV to 80mV is this correct?
The help for AI563 says that you can configure it's channels for -80...+80 mV range.
In this case the measuring range in your application will be -27648...27648.
Then it is a matter of scaling in your software for using in range 1...30 mV.
Your range will be 345.6....10368
Your signal's connection seems OK, don't forget to apply power supply to 19 and 20 terminals and configure your input for -80...+80mV range.
See the following warning from the help:
After powering up the system, input channels, which are configured will have undefined values /diagnosis message for typically 45 seconds, if the wires of all configured channels are broken.

I have positive 24VDC going to pin 19 and the negative going to pin 20
The only led on the AI563 is the power led. Yes I have the PLC in run mode
