Hi everyone,
I have been trying to work on an issue in AB MicroLogix Series C with an analog module IF4 for quite some time now, but now am reaching a frustration level.
What I have is a Omega Pressure Transducer on a circuit board. This transducer has three valuable pins. Pin 1 gets the Voltage, Pin 2 is grounded, and Pin3 provides the Output.
Now I have connected this Pin3 to the In0(+) of the analog while the In0(-) is grounded. If I take a voltmeter and read the voltage across, I do get a 0.5 V across the PLC contacts and circuit board, which is correct.
Additionally, I have properly configured the 'IO Configuration' in RS Logix 500 5.5. (Filter: 60 Hz, 450 ms, Input Range: -10 to 10VDC, Data Format:Raw/Proportional)
When I go online, I read the Data File Input Register I:1.0 but to no avail. It gives me a Radix Decimal value of approx 1534. The value does change if i provide some pressure to the Transducer.
My problem is that I can't relate this value of 1534 to anything. It doesn't appear to be a voltage or a current reading. Does anyone know how to appropriately interpret this value????
Any help would be greatly appreciated...
Thanks in advance !!
