If the Start Push Button (NO) is pressed, the program runs, and the Start Push Button is latched. It continuously monitors the analog input, normalizes and scales the analog input appropriately, and ...

4-20mA analog input from the signal generator is converted by the ADC (within PLC) to 0-27648 (integer). we use NORM_X provided function to normalize this range to 0-100% (real).

Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range.

In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...
