Beckhoff Automation elx6233

The ELX6233 allows direct connection of Ethernet-APL-capable field devices from the hazardous areas of zones 0/20 and 1/21. The sensors are supplied in accordance with the SPAA (TS10186) port profile and integrated via PROFINET. The flexible EtherCAT system architecture and ELX portfolio allow Ethernet-APL, HART, and simple digital signals to be integrated into the same terminal segment.   The Ethernet Advanced Physical Layer is a communication technology specially developed for the requirements of the process industry. Ethernet-APL describes only the physical transmission layer, based on the 10BASE-T1L single-pair Ethernet standard, and is therefore protocol-independent. With regard to use in hazardous areas, the IEC defines limits for the power supply to the field devices. The TS10186 technical specification developed by the Ethernet-APL project group prescribes guideline values based on these limit values and divides them into port profiles to simplify connectivity. Field devices from zones of the hazardous area can be connected depending on the port profile.
