Method and device for characterising the operating status of a control element

Abstract: The method involves controlling a process function of a region of a process plant by a control element in an active operating condition The control device is connected with the process plant, and the control element is functionally allocated for the process function An operational condition of the control element is identified as active, effective functional relation of the control element for the process function Independent claims are also included for the following: (1) a control device for controlling a process function of a range of processing unit (2) a process plant comprises a characterizing process area, and a control device

Messvorrichtung mit einem sicheren Messkanal

Abstract: Messvorrichtung (1) mit wenigstens zwei Messkanalen (2a, 2b), jeder Messkanal (2a, 2b) umfassend: – einen A/D-Wandler (4a, 4b) fur die Umwandlung einer analogen, Spannung in einen digitalen Spannungswert, und – eine Logikeinheit (5a, 5b), die mit dem A/D-Wandler (4a, 4b) verbunden ist, um den digitalen Spannungswert zu empfangen, dadurch gekennzeichnet, dass wenigstens ein, Messkanal (2a, 2b) als sicherer Messkanal (2a, 2b) mit einer hohen Zuverlassigkeit ausgefuhrt ist und einen Multiplexer (3a, 3b) aufweist, wobei mit dem Multiplexer (3a, 3b) die analoge Spannung zwischen einer Messspannung (UMess1, UMess2) und einer Referenzspannung (URef1, URef2) umschaltbar ist, und die Logikeinheit (5a, 5b) wenigstens eines anderen Messkanals (2a, 2b) als Referenzerzeuger ausgefuhrt ist, um die Referenzspannung (URef1, URef2) bereitzustellen und den Multiplexer (3a, 3b) zwischen, der Messspannung (UMess1, UMess2) und der Referenzspannung (URef1, URef2) umzuschalten.

Spring clamp used as electrical component plug has operating element acted on by external tool for opening clamp windows for insertion or removal of component current leads

Abstract: The spring clamp has a clamp housing (1) containing 2 mirror-symmetrical tension springs (3), each having a first arm (4) acting against a current rail (5) and a curved spring arm (6) with a clamp window (8) receiving the first arm, the current rail and the end of a component current lead (11), with opening of the clamp window via an operating element (12) engaged by an external tool The operating element is provided as an elastic body with opposing side surfaces (17) pushed outwards into engagement with the spring arms of the tension springs upon insertion of the tool

Method for calculating a topology, network components and central unit

Abstract: The method involves recording an end position (25) coming from an end component in a line of a plane in a data field (22) of a telegram (T). The telegram is transferred in the direction of a starting component to a central processing unit. A topology is detected in the central processing unit according to the data field. Independent claims are included for the following: (1) a network component with an inlet or outlet port; and (2) a central processing unit for the connection at a data network.

Alternative synchronisation connections between redundant control units

Abstract: The redundant control system comprises an automation network (1) having two control devices (10,20). The control devices are connected over network interfaces (11,21) for data communication with the automation network. The control devices are connected together for direct communication with each other over a point-to-point link assembly (2). The control devices are adapted to establish an alternative communication over the automation network, if the direct communication is not available over the point-to-point link assembly. An independent claim is included for method for operating redundant control system.
