Hi everybody
Does anybody have experience with the Analog input card 1746-N18?
Cannot get the last 4 inputs (4-7) to work like the first 4 (0-3) inputs. They are set to input type 4-20ma using 1746-N14 data format. First 4 inputs work perfectly but nothing on the last 4. The AB manual says that I need to configure the input types to +-20ma (page C3) and this doesn't even work either. Could the card be bad? I need to use the 4-20ma option for all 8 inputs. On the last 4 inputs, if I don't enter 110 in the output table for this card, the representing input lights flash on the card. Any ideas?
