METRACAL CM - HART Extension

Item number: Z275T

Function extension HART communication (Highway Addressable Remote Transducer)

With the HART communication function, the process calibrator can read, process and configure digital signals from HART-capable field devices, in addition to the analog 4 mA ... 20 mA signal. This allows parameters such as measuring span, damping or TAG names to be set directly on the calibrator. This simplifies commissioning, troubleshooting and calibration.

Supported HART commands
Command 0: Read unique identifier
Command 2: Read loop current and percent of range
Command 3: Read Dynamic Variables and percantage of Range
Command 8: Read dynamic variable classification
Command 13: Read Tag, Desctiptor, Date
Command 15: Read device information
Command 18: Write Tag, Desctiptor, Date
Command 35: Write primary variable range values
Command 34: Write primary variable damping value
Command 40: Enter/Exit fixed current mode
Command 43: Set primary variable Zero
Command 44: Write primary variable Units
Command 45: Trim loop current Zero
Command 46: Trim loop current gain
