To avoid false alarms, you can define warning thresholds. Each warning is assigned on and off thresholds. This enables parameterization of a hysteresis meeting the requirement of the application. When a warning is triggered, the corresponding bit is entered in parameter P 0034 ERR_WRN_State. The binary value enables a status interrogation. Warnings can also be programmed onto digital outputs.
Before an error is triggered, warning thresholds can be defined with P 0730 MON_WarningLevel .

Adaptation of switching hysteresis (warning thresholds):
No message is issued in the hysteresis range. So when a warning is parameterized the hysteresis window must be adapted for the corresponding warning. The upper and lower limits of the window must be programmed.
