Operating functions via HART communication

Requirement
The following is required to operate the transmitter via HART communication:
• A HART Communicator or PC software such as SIMATIC PDM.
• A HART modem to connect a PC with the transmitter or a lead to connect a HART
Introduction
The transmitter can be operated via HART communication. The full functionality of the
transmitter is available via HART communication. The HART Communicator and PC
software are not supplied with the transmitter. How to connect and operate a HART
Communicator or the PC software is described in separate operating instructions or in the
online help for both these tools.
As soon as you have set up the HART communication and the transmitter, you can adapt the
transmitter to your relevant measuring task by setting a few parameters. When doing so you
are assisted by the measurement types "Pressure", "Level" and a user programmable
"Characteristic curve". One or more device variables are permanently allocated to each
measurement type (measurement block). These device variables are displayed via PC
software such as SIMATIC PDM or via a HART Communicator.
The following components are described in more detail in these operating instructions:
• Process tag data
• Measurement
• Selecting the measurement types
• Measurement type selector/mapper
• Variable mapper
• Measurement type "Pressure"
• Measurement type "Level"
• User-specific characteristic
• Measurement type "User"
• Measured value status
• Analog output
