A safety relay configuration system for configuring safety functions to be carried out by a safety relay is provided. The configuration system comprises a number of features that facilitate intuitive and simplified configuration of an industrial safety relay, including but not limited to features that guide the user through the configuration process using an intuitive sequential procedure that provides feedback and prompts based on user interaction, enforce design consistency throughout the configuration project by intelligently limiting user selections, and visually organize configuration and status information in a manner that efficiently utilizes display space and allows the user to quickly evaluate available configuration options.

A safety switching device for fail-safely switching on and off an electrical load, and to a system comprising at least two safety switching devices which interact in a fail-safe manner via a single-channel. The safety switching device comprises a fail-safe control unit, a first and a second electronic switching element connected with a first and a second output terminal; and at least one input terminal for receiving a first switching signal that causes a switching of said switching elements. Said first and second switching elements each comprise an output which provides depending on the first switching signal an output signal having a first or second potential. A third output terminal connects said safety switching device to a second safety switching device, providing a clocked signal depending on the first switching signal and being monitored by said control unit for performing a cross fault detection.

Single-channel safety output

A single-wire safety system architecture is provided that yields reliable safety device monitoring without the need for dual redundant signal channels. The safety system comprises a safety relay acting as a communications master device and one or more compatible safety input devices connected in series with the safety relay via a single-wire communication circuit. The safety input device farthest from the safety relay on the safety circuit modulates a safety signal with a recognizable pulse pattern that traverses the single-wire safety circuit to the safety relay via the intermediate safety devices. The safety relay maintains safety mode as long as the pulse pattern is received and recognized. In addition to conveying the safety signal, the architecture allows bi-directional communication of initialization, configuration, and diagnostic messages over the single-wire safety channel. The architecture also facilitates rapid initialization of the safety channel using asynchronous sub-link detection and device enumeration.

Development environment for a safety relay configuration system

The present invention relates to a safety switching device for actuating actuators in a fail-safe manner, and further relates to an emergency shut-off circuit comprising a safety switching device according to the present invention. The safety switching device includes at least one first and second safety input for receiving a first and second input signal, at least one first and second safety output for transmitting a first and second output signal, and a control unit for evaluating said input signals and for generating said output signals. The first and second safety outputs further comprise a feedback loop said that couples the output signals back to the control unit such that the control unit is operable to perform a test routine for testing said output signals.

Safety switching device with universal signal input

A method, system, and a control device are provided for reducing RFID reaction times. A control unit receives a data signal, which comprises a code signal if a passive RFID transponder is located in the carrier field of an RFID reader. The code represents the identification code of the passive RFID transponder. The carrier field is disabled to reset the data signal, and thereafter enabled to receive a first portion of the code signal only. The code of the passive RFID transponder is then validated on the basis of said first portion of the code signal only.

RFID reaction time reduction

A modular safety system for controlling emergency stop applications includes a plurality of inputs, a plurality of output groups, and a plurality of safe relay outputs. The plurality of inputs is assigned to at least one of the output groups. Each output group is configured to control at least one of the plurality of safe relay outputs. The system also includes means for configuring the system and at least three freely programmable output groups.

Configurable modular safety system

A modular safety system for safety control in emergency stop applications includes a base module and at least one extension module, wherein each module is arranged in a housing with a rail-mounting base, so that the modules are located in a side-by-side arrangement when mounted to the rail. The modular safety system also includes means for setting of required input and output functions, wherein the setting means is located in a side wall of the module housing, so that after mounting the modules to the rail, the setting means is covered by an adjacent module.
