The invention relates to a method and system for diagnosing communication connections in a communication system. The invention enables the provision of a plurality of first diagnosis units and at least one second diagnosis unit, wherein the first and second diagnosis units each are assigned to a communication connection of the communication system and are configured for determining a value of a diagnosis variable of the respectively assigned communication connections, and provides for determining a value of at least one diagnosis variable by each of the first diagnosis units, determining a value of at least one diagnosis variable by the at least one second diagnosis unit, transferring the values determined by the first diagnosis units to an evaluation unit, statistically evaluating the transferred values by the evaluation unit, and diagnosing the values determined by the at least one second diagnosis unit depending on the statistical evaluation by the evaluation unit.

Methods for accessing a control module that can be executed in a control device of an automating system are provided. The method includes the steps of providing the control module in the control device; providing a first interface module in the control device; providing a second interface module in the control device; connecting the control device with an operating device via a network; transferring the second interface module from the control device to the operating device, whereby the operating device comprises input and output devices for operation by a user; executing the second interface module by the operating device; and transferring data between the first and the second interface modules.

For determination of the bandwidth of optical fibers, the invention proposes a method which comprises the injection of light at a first optical power level and at a first frequency into an optical fiber, as well as the measurement of a first signal level as a function of the optical power level of the light passing through the fiber at the first frequency, the injection of light at the second optical power level and at a second frequency into the optical fiber, the measurement of a second signal level as a function of the optical power level of the light passing through the fiber at the second frequency, and the determination of the bandwidth of the fiber as a function of the first and second optical power levels and/or of the measured first and second signal levels using a predetermined rule which describes the frequency-dependant attenuation response of the fiber.

A circuit arrangement allows data, which are necessary for building up fault-tolerant structures, to be transmitted on standard ring-shaped bus systems. Its implementation requires a monitoring unit and input and output units which transmit or receive data for control. The circuit arrangement handles the task of detecting any faults which can become a danger for the process within a machine or plant. Due to its internal configuration, the circuit arrangement identifies any fault even before the detection of the fault and initiates a protected switch-off. In this arrangement, it is of no importance whether it is the external control unit or the bus system used which is responsible for the fault.

A control and data transmission installation and a process for transmission of safely-related data in a control and data transmission installation. In accordance with the invention, safety procedures of existing field bus systems, particularly the interbus, are improved in such a way that there is no need either for additional lines for the transmission of control signals or redundant, safety-related units. In the inventive control and data installation, a master control device and a number of bus subscribers each include respective safety-related devices for carrying out predetermined safety functions. The safety-related devices can communicate with each other by way of a field bus.

An input/output module (1) with a terminal unit (2) for connection of sensors or actuators with an electronic unit (3) and with a bus connection element (4). The terminal unit (2) has at least one input/output (5) located in a surface thereof and the terminal unit is connected by the electronic unit (3) to the bus connection element (4). To replace the electronic unit (3), the terminal unit (2) can be removed from the electronic unit (3) without the need to remove lines (6) connected to the inputs/outputs (5). The terminal unit (2) is able to be mounted to the electronic unit (3) in each of two positions, the input/output (5) in the two positions lying in planes that are offset relative to each other by 90.degree..

Electronic input/output module

A terminal for at least one fiberoptic cable comprising a housing with a front face having at least one slot therein for receiving an end of a fiberoptic cable, at least one optical transmitter and/or receiver, a fitting element which is movable within the housing by sliding and which has at least one insertion opening for a fiberoptic cable to be joined to the at least one transmitter and/or receiver, and with a cutter which has at least one blade. The at least one insertion opening of the fitting element and an actuating arrangement for sliding of the fitting element between a mounting position for receiving the at least one fiberoptic cable and an operating position in which the at least one fiberoptic cable is joined to the at least one transmitter and/or receiver are at the same side of the housing. The housing is provided with at least one cable duct for discharging cut-off pieces of the at least one fiber optic cable. Additionally, longitudinal ribs can be formed on an inner face of the at least one slot means for relieving strain on a fiberoptic cable pushed into the at least one slot between the longitudinal ribs.
