The system-integrated solution for explosion protection: PC-based control
HART field devices integrated simply: with PC-based control from Beckhoff
The ELX4181 analog EtherCAT output terminal allows the direct connection of intrinsically safe HART-capable field devices located in hazardous areas classified zone 0/20 or 1/21. For example, the ELX4181 can be used to control intrinsically safe controllers for control valves. The status and error LEDs provide information on the status of the HART communication and indicate any communication errors.
The HART protocol (Highway Addressable Remote Transducer) enables two-way communication through digital data transfer via the analog 4…20 mA wiring. In this way, in addition to the analog current signal, further data can be exchanged with the field device via the superimposed digital signal.
The HART communication can also be used for the FDT/DTM concept. The TwinCAT FDT container enables the integration of field device DTMs into TwinCAT Engineering, so that the device configuration and diagnostic functions are available directly within the development environment.
