Eckelmann is extending the modular, configurable safety system E°SLC with a CAN fieldbus coupler (CANopen). The fieldbus connection allows the direct transmission of the complete process image and internal states of the safety module. A maximum of 87 safe signals can be transmitted. All information regarding safety functions is thus readily available at any time at the level of control and operation. Additional wiring is not necessary. Moreover, any desired signals or pre-processed signals can be configured for transfer to the CAN bus coupler via drag & drop using the graphical E°SLC configuration tool Safeconf. The bus coupler offers machine builders the advantage of being able to use the information from all safety circuits in user interfaces and machine visualization and for expanded fault diagnostic functions without high costs.
