Tutorial: Integration of HART Field devices into TwinCAT

The EL3184 analog input terminal for HART-capable field devices supplies measuring transducers located in the field and transmits their analog measuring signals to the automation device under electrical isolation. With a technical measuring range of 107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43.

The EL6184 offers four interfaces for integrating HART-capable field devices. The EtherCAT Terminal serves as a secondary master and can be seamlessly integrated into existing connections. Maintenance and diagnostic data, for example, can be retrieved from field devices, as is the case in the context of NAMUR Open Architecture (NOA).

The ELX318x analog input terminal allows the direct connection of intrinsically safe HART-capable field devices located in hazardous areas classified zone 0/20 or 1/21. It supplies measuring transducers located in the field and transmits their analog measuring signals electrically isolated to the automation device. Overload and open-circuit detection are signaled by the error LEDs, furthermore LEDs inform about the status of the HART communication and signal any communication errors. The EtherCAT Terminal indicates the signal state by means of light emitting diodes.
