How do I Monitor Analog Input Over-Under Range conditions on a SCADAPack 350?
Only the Scadapack models 314, 334 and 357 (only AI on the 5606 Lower IO board) have register assignments that monitor the out-of-range status for analog inputs.
The only way to monitor if an analog input has failed, would be to monitor the raw input and look for a zero or full scale value.
For a SP350 using a 5V/20mA register assignment and a 4-20mA input:The screen shot below shows logic that scales the raw value of input 30001 to produce a scaled value in register 40110 (in mA)

For a SP350 using a 10V/40mA register assignment and a 4-20mA input:
The screen shot below shows logic that scales the raw value of input 30001 to produce a scaled value in register 40110 (in mA)
