DE102010052192A1 Method for addressing multi-slaves of e.g. sensor in actuator sensor-interface, involves holding remaining partial-slaves in inactive condition, and providing multi-slaves of type with same combination of profiles of partial-slaves
DE102010033447A1 Method for parallel transmission of non-safety-related single-bit input signal and safe value using safety-at-work input slave, involves recognizing non-safety related on-signal by program created for application process in safety monitor
DE102009030257A1 Repeater for ActionScript-interfaces of networks for refreshment of ActionScript -interface telegrams, which are exchanged between Master and Slaves, has two sides and two channels with receiver and transmitter
DE102008060866A1 Safety-at-work network module, has safety-related inlets and outlets assigned to slave parts, and individual slaves-parts whose addresses are set, where addresses of individual slaves-parts are identical or different from each other
DE102008057003A1 Method for safe parameterization of actuator-sensor interface slaves, involves transferring entered parameter values of pattern from higher-level control unit to slave, where parameter values are stored at slave in safe manner
DE102008008647A1 Earth fault monitor for e.g. controller-device interface network, has alternative voltage earth connection registered in direct current moderate earthed autonomous system interface networks on basis of alternative voltage measurement
DE102007049578A1 Safety monitor for safety-at-work network, has interfaces for Ethernet and safety-at work-network respectively, where monitor exchanges current status data of network with another safety monitor over Ethernet interface
DE102007024643A1 Fast repeater for actuator sensor-interface network, has channels with signal path comprising receiver for checking voltage pulse of each telegram and initiating respective transmitter in case of invalid signal
DE102007018391A1 Safety-related input slave for actuator sensor interface safety-at-work network, controls fast, safety-related outputs in addition to data path over network and passes input values to standard master and safety monitor
