Field equipment
專利匯可以提供Field equipment專利檢索，專利查詢，專利分析的服務(wù)。并且PURPOSE: To prevent abnormality capable of occurring afterwards for a whole system by detecting the abnormality of a receiving signal level on a transmission line, and informing other equipments on a field bus of the detected abnormality.
CONSTITUTION: A signal level detection circuit 104 receives the same communication signal on the transmission line that a demodulation circuit 113 receives, and in the case that the amplitude of this signal is larger than a prescribed value, it decides the existence of the abnormality, and outputs an abnormality signal to an I/O interface 106. A microprocessor 101 recognizes the existence of the abnormality through the I/O interface 106, and sends the purport that the abnormality exists on the transmission line to other field equipments and host equipment as the communication signal. Thus, a fatal system abnormal state that the whole field falls into a communication impossible state can be prevented.
