FMD 88-10
« on: August 30, 2014, 05:12:05 AM »
The ADC of the FMD 88-10 is not measuring, ADC 1-8.

The plc stopt measuring the analog inputs.
When i put a voltage between 0-4V on the inputs the adc stays 0v.

Grounds are connected.

What can be wrong ?

ADC() function MUST BE RUN in order to show up on the View Variable screen.

Remember that the ADC #1 is on Pin 8 of the DB15 connector (female). ADC #2 on Pin 7.... ADC #8 on pin 1. So please check that you apply to the correct pin.

Run a simple FOR loop to read ALL 8 ADC channels so that you can see which ADC is being energized:

FOR I = 1 to 8
    DM = ADC(I)
NEXT

ADC() function MUST BE RUN in order to show up on the View Variable screen.
