Abstract: A diagnostic module for technical diagnosis of field devices operated in an automation plant, a diagnostic system, a method, and a computer program are provided. The diagnostic module includes a local control device which has a field bus interface and is not web-enabled, a field device, which has a web-based interface, from a number of field devices, and a coupling module with a web interface for data communication with a cloud-based server and in particular for reception of an analysis message from the cloud-based server and with a conversion module for generation of a field bus message from the received analysis message and for transmission of the field bus message to the control device. The diagnostic module further includes a field bus for internal communication between the devices of the automation plant and for forwarding the generated field bus message to the control device for control of the automation plant.

Abstract: A modular arrangement is proposed with modules (10-25) added in a row direction, these being constructed at least partially as valve modules (16-21, 23, 24), wherein one module is constructed as a control module (10) and is connected to the other modules (11-25) by control and/or sensor lines (30) running transversely through these modules. Voltage supply lines (36, 37) powered by a voltage source (33) run transversely through the modules (10-25). At least one module is constructed as a safety module (12) and has a switching arrangement (38) for interrupting the voltage supply lines (36) to the modules (13-21) powered via the safety module (12) in the activated state. Safety-related control and/or diagnostic electronics are provided for activating the switching arrangement (38).

Abstract: A device or arrangement for exchanging data between a main station (master) (10) and at least one secondary station (slave) (12, 12n), which each have access to at least one common data line (11) via interfaces CAN, and processes for operating the device. Except for an individual identifier (a, b, . . . , d) of each slave (12, 12n), which is stored in an identifier memory (27, 27n) disposed in the slave (12, 12n), the slaves (12, 12n) are identical. The master (10) likewise includes an identifier memory (22), in which the identifiers (a, b, . . . , d) of the slaves (12, 12n) are to be stored, so that the master can address the slaves (12, 12n) in a targeted way and can process the data output by the slaves (12, 12n). The processes according to the invention pertain to the storage of the identifiers (a, b, . . .

Abstract: A method for detecting faulty switching operations of a first relay whose switching element is connected in series with a load and which, depending on the switch position, interrupts or closes the connection to the load in accordance with switching commands. In this context, a current is detected flowing through a circuit containing the switching element, and a faulty function of the relay, in particular a sticking of the switching element, is detected if the current intensity does not correspond to the current intensity to be expected in accordance with the selected switching position. Further relays, which can be provided in order to commutate the potentials at the load, can be included in the test. The method makes possible a relay test without moving the actuators, assuming the relays are in order. In addition, this generates a time savings, since not all of the relays have to be triggered for the test.

Abstract: A convertible-top system for a motor vehicle has a signal-processing arrangement for detecting actuating commands and for controlling drive mechanisms for the convertible-top system in open and/or closed loop as a function of the actuating commands. The signal-processing arrangement emits signals, which are a function of the state of the convertible-top system, to at least one operating device of at least one external component not belonging to the convertible-top system. The external components are influenced by way of the control signals.
