Sensor system for plant monitoring

摘要

A sensor system includes at least one safety sensor unit for monitoring a safety relevant zone of a plant. The sensor system also includes a display unit connected to the sensory unit or integrated into it. The sensor system outputs a safety switch signal on an intrusion of an unpermitted object into the monitored, safety relevant zone and the safety sensor unit has an input interface for receiving a further safety switch signal. The input interface can be configured such that, on the one hand, it can receive the further safety switch signal and, on the other hand, can also receive external, non-safety relevant signals of an external device. The display unit is designed to display internal state data of the sensor system and information resulting from the external non-safety relevant signals.

1. A sensor system which comprises a safety sensor unit for monitoring a safety relevant zone of a plant as well as a display unit connected to the safety sensor unit or integrated into it, wherein the sensor system outputs a safety switch signal on an intrusion of an unpermitted object into the monitored, safety relevant zone and the safety sensor unit has an input interface for receiving a further safety switch signal, wherein the input interface can be configured such that, on the one hand, it can receive the further safety switch signal and, on the other hand, can also receive external, non-safety relevant signals, of an external device and the display unit is designed to display internal state data of the sensor system and information resulting from the external non-safety relevant signals,
wherein the display unit can be shut down in dependence on the received information.
