We have an Allen Bradley PLC programmed by others. I have two analogue inputs connected and their inputs are programmed to a SCP Scale with parameters block. The two 4 to 20 mA inputs are from gas monitors ant the range of the monitors is 0 to 90 parts per billion. Both inputs are the same and perform the same functions. However, both SCP blocks are scaled differently and ask if one of them is incorrect.
4 to 20 mA input = 0 to 90 PPB. Block 1 is programmed as Input min = 3277 Input max = 16384 Scaled min = 0 Scaled max =90Block 2 is programmed as Input min = 3277 Input max = 16384 Scaled min = 0 Scaled max =900
Appreciate any advice. TIA
