The analog ELX4184 EtherCAT output terminal allows intrinsically safe HART-capable field devices from hazardous areas in zones 0/20 and 1/21 to be connected directly. The ELX4184 can be used to control intrinsically safe controllers for control valves, for example. The status and error LEDs provide information about the state of the HART communication and signal any communication errors.
The HART (Highway Addressable Remote Transducer) protocol enables two-way communication through digital data transfer via the analog 4…20 mA wiring. In this way, further data can be exchanged with the field device via the superimposed digital signal, in addition to the analog current signal.
HART communication can also be used for the FDT/DTM concept. The TwinCAT FDT Container enables field device DTMs to be directly integrated into TwinCAT Engineering. This means that field device configuration and diagnostics are already available in the development environment. As the FDT concept only supports 32 bits, it cannot be applied in the 64-bit TwinCAT XAE Shell.
