A field bus module for the operation of actuators and/or sensors with at least one device interface for the connection of a sensor and/or actuator, with at least one field bus interface for connection to a field bus system, and with a processing device for receiving and processing and sending field bus telegrams and also for making available control commands, especially safety-oriented control commands, to the device interface depending on incoming field bus telegrams wherein the processing device is configured to process in different operating modes sensor data that can be made available at the device interface and/or field bus telegrams that can be made available at the field bus interface, wherein an operating mode memory is allocated to the processing device for the optional provision of one of at least two different operating mode data sets at the processing device depending on an incoming field bus telegram.

Field bus module, machine controller, and method for parameterizing a field bus module, in particular a safety-oriented field bus module

A signal converter circuit includes a sensor connection, two comparator circuits, each having a signal input for an electric connection to the sensor connection, a reference input for an electric connection to a respectively assigned reference signal source and a signal output for a provision of an output signal, with a feedback line being formed between the respective signal output and the respective reference input, and further including two reference signal sources, each of the comparator circuits being configured for comparing a signal level at the signal input to a signal level at the reference input and for outputting a digital output signal as a function of a comparison result between the signal levels, wherein the two reference signal inputs are connected to one another via a coupling line being configured to transmit a presettable fraction of the respective signal level present at one reference input to the other reference input.

Signal converter circuit and method for evaluating a sensor signal of a safety-oriented device

A monitoring device for monitoring safety components including monitoring electronics which include a plurality of clock generators and evaluation means and on which at least two interfaces to be monitored for electric coupling to safety components are formed, wherein each of the interfaces includes at least two output ports and at least two input ports, wherein each of a first output port and a second output port is connected to a clock generator designed for providing clocked electric monitoring signals, wherein a first input port and a second input port are connected to the evaluation means, and wherein a number of clock generators greater than two and less than a number of all output ports of the interfaces to be monitored is chosen.
