The EL6233 allows the direct connection of Ethernet-AL-capable field devices. The sensors are supplied in accordance with the SPCX port profile and integrated via PROFINET. Thanks to the flexible EtherCAT system architecture and the EL portfolio, Ethernet-APL, HART or simple digital signals can be integrated in the same terminal segment.

The Ethernet Advanced Physical Layer is a communication technology specially developed for the requirements of the process industry. Ethernet-APL only describes 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 limit values 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 hazardous area zones can be connected, depending on the port profile.

The EL6233 allows integration of field devices from zone 2/22 hazardous areas. The ELX6233 can be used for integration of field devices from zones 0/20 and 1/21.
