Electronic terminal for use on circuit boards

Abstract: A terminal has a box spring out of whose wall there is cut at least one elastic terminal leg which is bent into the inside of the box toward an opposing abutment and which has a free terminal end between which the abutment and an electric conductor can be clamped. An actuating part having a projecting pusher end is arranged in the box spring and can be displaced toward the terminal end of the terminal leg. When pushed in, the actuating part with its inside end is pushed as a wedge between the abutment and the terminal leg, thus releasing a clamped electric conductor. The actuating part has a through-channel for insertion of the electric conductor which extends from the conductor insertion orifice on the pusher end to a conductor outlet orifice.

Measurement, analysis and modeling of real-time source data traffic in factory communication systems

Abstract: In the performance evaluation and design of communication systems for distributed automation systems the almost realistic modeling of the data traffic of automation devices plays a decisive part. Therefore the real-time communication behaviour of a high-grade automated installation in the discrete manufacturing is evaluated. Selected communication requirements are analysed and transferred to a analytic model. This model finally is validated.

Apparatus for electronic monitoring of the supply current of modules connected to a bus

Abstract: The invention relates to an apparatus for electronic monitoring of the supply current of modules connected to a bus, in particular for monitoring the supply current of bus devices of an automation bus system. The object of the invention is to provide an apparatus for electronic monitoring of the supply current of modules connected to a bus, which on the one hand, if required, carries out reliable isolation from the supply voltage, and simultaneously maintains the diagnostics capability for the purpose of fault locating.
