You can define a discrepancy value for input currents on dual input and triple input configurations. If the input channels
read currents that differ by more than the defined parameter after the discrepancy time has expired, the module FPGA will
return a Discrepancy Fault or a Discrepancy Warning to the User Program, based on your configuration.
Figure 1. Discrepancy Current
To maximize the effectiveness of discrepancy current detection, set the discrepancy current parameter as low as the system
will allow. In most systems, the discrepancy current should be significantly less than the normal current range (high threshold -
You must set the discrepancy current greater than 0 mA.
