Yes, the Channel Status LEDs on a 1734-IE2V indicate that the incoming signal is out of range.

If the module is configured for -10 to +10 V DC, then the voltage could be either under -10.0 or over +10.0 volts.

The data values in the controller itself will tell you the actual values of voltage, at least up to the +/- 10.5 volt measuring threshold.

Thanks. It happens only some times. How do I solve this .Since it goes over range my input scaled reading gives a wrong value.
