Overview

Description
HART communication allows you to activate and evaluate a wide range of diagnostic
functions from a central control room or onsite:
• Calibration/service timer
• Min/max pointer
• Limit monitoring modules
• Simulation of measured pressure and temperature values
• Limit monitoring of all device variables
The diagnostics strategy employed for SITRANS P300 incorporates a diagnostic warning
and a diagnostic interrupt for diagnostic functions for monitoring limit values, e.g. for
monitoring current saturation. This warning and interrupt can be configured:
• Diagnostic warning: The device transmits via HART communication the diagnostic event
• Diagnostic interrupt: The device goes into the fault current state. The message
In the default settings, all warnings and alarms are switched off. You can choose to set either
the diagnostic warning only or the diagnostic interrupt and warning. For HART
communication, use the HART Communicator or PC software such as SIMATIC PDM. To
