AB Micrologix 1200 Analog Input Module

2 posts in this topic

I have a ML1200 Ser C Rev F with a 1762-IR4 RTD/Resistance Module and can't get it to work. The green light comes on on the module and no errors are showing up in the controller. I'm using RSLogix500 ver.5.00. I've set up the module in the I/O configuration using the other type I/O module and have configured the input words and configuration data, which includes setting an enable bit for each channel. I'm trying to get a 1000 ohm POT to read, but don't get any data or errors to show up in the input words. I did have the processor in RUN mode. I did enable the channel through the configuration word for that channel, bit 15 is the enable bit. Also, the configuration file is only read on going to run, so I've tried switching from program to run and have also cycled power. I also enabled the next channel that has nothing connected to it, and it doesn't show any errors either. I'd expect an open circuit indication? Any ideas?

Support for the 1762-IR4 module wasn't added to RSLogix 500 until V 5.20.00.
