An analog signal input circuit with a first number of analog signal detection channels and a diagnostics circuit, with each analog signal detection channel including a third number of analog signal detection circuits and a first connection selection device, and each analog signal detection circuit comprising a first connection device and a second connection device. For each analog signal detection channel, for detecting analog input signals applied at analog signal inputs from a second number of analog signal inputs, and for the respective issuance of output signals for the detected analog input signals, respectively one analog signal detection circuit is alternatingly selected for a certain period of time, not connected to its first connection device comprising an analog signal input for detecting an analog input signal, but used for testing and/or diagnostic purposes.

Analog signal input circuit to process analog input signals for the safety of a process

The invention relates to an automated system in which a targeted search may be made for connecting terminals without having to actuate a load connected thereto. For this purpose, the automated system has a communication network, a programmable control unit, and at least one modular bus subscriber which are connected to the communication network. The modular bus subscriber has multiple groups of connecting elements, a display element being associated with each group of connecting elements. An evaluation and control unit is also provided which actuates at least one selected display element in response to signaling information originating from the programmable control unit. The programmable control unit is designed to provide this type of signaling information.

Automated system and control device for identifying a connecting element

The invention relates to a method for monitoring an output driver that can be parameterized and is suitable for controlling actuators in industrial automation technology, for applying analog signals to an output channel, with the following steps: determining resulting internal leakage power based on the parameterization data provided for parameterizing the output driver, comparing the leakage power relative to a leakage power limiting value, and, dependent functionally on the comparison result, stopping the application of an analog signal on the output channel corresponding to the parameterization data provided for parameterizing the output driver. The invention further relates to an analog signal output device, suitable for controlling actuators in industrial automation technology and in accordance with the aforementioned method, comprising at least one output driver and a monitoring device.
