Diagnostics WAGO-I/O-SYSTEM 750 750-450 4 AI RTD Diagnostics Error Response The response of the I/O module in the event of an error depends on the configuration for wire break / short circuit monitoring, under-range / over-range monitoring and limit upper/lower limit violation monitoring. You can activate/deactivate these diagnostics functions in Register 35.
WAGO-I/O-SYSTEM 750 Diagnostics 750-450 4 AI RTD Temperature Measurement: Restriction for short-circuit detection! With 3- and 4-wire connection technology, short-circuit detection is not possible between the +R and +RL connections. With 4-wire connection technology, short-circuit detection is not possible between the −R and +RL connections.
