Method for determining motion condition of object i.e. rotary body, using signal generator e.g. incremental encoder, involves determining motion condition of object from relative periodic time

Abstract: The method involves supplying phase shifted output signals of a signal generator (10) eg incremental encoder A position change is determined during a time interval in an evaluation unit (20) based on the output signals An absolute periodic time is measured in the evaluation unit during the time interval based on one of the output signals A relative periodic time is calculated when the time interval is larger than zero, and is defined by a ratio of sum of the determined absolute periodic time and position change A motion condition of object is determined from the relative periodic time An independent claim is also included for a device for determining a motion condition of object using a signal generator, comprising a quadrate decoder

Hierarchical network having decentralized administration

Abstract: The invention relates to a network comprising at least one first client (2), one second client (3a, 3b), one third client (4a, 4b, 4c, 4d) and one message transmission device (6) for transmitting messages between the clients, wherein the first client (2) is arranged in a first network level, the second client (3a, 3b) is arranged in a second network level and the third client (4a, 4b, 4c, 4d) is arranged in a third network level, wherein the first network level is superior to the second network level and the second network level is superior to the third network level, wherein the network is configured so that the second client (3a, 3b) and the third client (4a, 4b, 4c, 4d) can initiate the transfer of a message between the second client (3a, 3b) and the third client (4a, 4b, 4c, 4d), wherein the transfer of the message is restricted to the transfer of the message between the second network level and the third network level.

Method and device for monitoring security in an automation control device includes an automation device with a controller and a central monitoring device with direct in- and output devices and a serial bus connection.

Abstract: An automation device (1) with a controller (2) and a central monitoring device (3) has direct in- and output devices (4) and a serial bus connection (5). All data required for controlling and/or checking an automation process can be transferred directly via the in- and output devices or the serial bus connection to the automation device or be transmitted from it. The serial bus connection links the automation device to a bus system (6).
