Abstract:
The invention relates to a programmable controller comprising modules (3) connecting to each other by way of a backplane bus (1) which is mounted in a substantially C-shaped, electrically conductive mounting rack (2). Consequently, said backplane bus (1) is enclosed by the mounting rack (2) on three sides, the modules (3) being mounted on the mounting rack (2) with the result that they are mechanically supported thereon, are electrically connected to the backplane bus (1) and have a direct earth connection to said mounting rack (2).
Abstract:
To program addresses, the integrated circuit (2) of a user module (1) must be separable from the ASI system on start-up and connectable to an adapter (11) of a programming device. To this end the plug connectors (3) acting as line connectors between the circuit (2) and the bus line (5) are disconnected. This disconnection is bridged by short-circuit bridges fitted at the rear to a removable data plate (9) penetrating the front plate (13) of the user module (1).
Abstract:
A modular input/output arrangement for a programmable controller. The rack assembly of the invention permits selected plug-in input/output modules to interconnect the system being controlled and the processor of the controller. The invention also provides input and output simulator modules which may be plugged into the rack assembly to test operation of the system.
Abstract:
The invention relates to a device for the inherently safe matching of the signals to be exchanged between an automation system (2) and field devices (3). The device (1) comprises on its rear wall (19) plug-in input/output modules (4) which combine the functions of conventional input/output and potentional separation units. The rear wall plate (19) carries data lines (20) of a local bus (8) and power supply lines (21). A communication module (9) is in communication on one side with the local bus (8) and on the other with a field bus (12). The communication module (9) contains devices for data storage (22) and data processing (16) and permits asynchronous data exchange between an automation system (2) and the input/output modules (4).
Abstract:
The invention relates to a security module for connection to an automation device or automation system, which is provided for the control of safety-critical and non-safety-critical processes and/or system components, comprising a communication board (LP1), the processing unit (14) of which can be connected to a central unit (CL) via an input/output bus slave (12) and an external input/output bus (IOB1) connected thereto. The communication board (LP1) comprises a serial communication master (10) connected via at least one communication link (IKB1), which can be connected to said communication master, to one or more secure processing units (24), (34) arranged on one or more printed circuit boards (LSP1), (LSP2) having safety-related input/output circuits (23), (33) for safety-related functions so that at least one of the printed circuit boards (LSP1), (LSP2) is provided to receive the telegrammes sent by the communication board. An internal communication slave (20), (30) is provided on the printed circuit boards (LSP1), (LSP2) for safety-relevant functions, which can be connected to the serial communication master (10) via the internal communication link (IKB1), (IKB2). Safety-related telegrammes can only be transmitted from and/or to the processing unit (14) of the communication board (LP1) via one of the secure processing units (24) which are located on teh printed circuit boards (LSP1), (LSP2) for the safety-related functions by means of at least one second internal communication link (IKB2).
