I am adding scale weight inputs (4-20MA) to a existing program, using analog input card (1746-NI16I- Class 3). Processor is 1747-L542C 5/04 CPU. I have been using the card for other 4-20 inputs, I have been unable to configure the additional channels to show the input. I set program up the same as others, using SLC blocks to scale the inputs and send them to panalview. I have been through the manual and setup with no success. I have went through the status word tables and tried changing bits to enable the additional channels, the bits change back to zero. I have also tried changing offline and downloading new congfig. with same result. I tried switching with another card, same result. I have the 4-20MA signal to the card, I checked with meter to verify signal and polarity. I keep thinking I am missing something simple, any suggestions?
