5.4 Communication
In addition to via local operation, the measuring device can also be configured and measured values
obtained by means of the HART protocol. Digital communication takes place using the 4 to 20 mA
HART current output ä 33.
The HART protocol allows the transfer of measuring and device data between the HART master and
the field devices for configuration and diagnostics purposes. HART masters, such as a handheld
terminal or PC-based operating programs (such as FieldCare), require device description (DD) files.
They are used to access all the information in a HART device. Such information is transferred solely
via "commands".
There are three different command classes:
• Universal commands:
All HART devices support and use universal commands. These are associated with the following
functionalities for example:
– Recognizing HART devices
– Reading off digital measured values (flow, totalizer, etc.)
• Common practice commands:
Common practice commands offer functions which are supported and can be executed by many
but not all field devices.
• Device-specific commands:
These commands allow access to device-specific functions which are not HART standard. Such
commands access individual field device information, (among other things), such as low flow cut
off settings, etc.
!
Note!
The measuring device has access to all three command classes.
List of all ''Universal Commands" and "Common Practice Commands" ä 42.
5.4.1 Operating options
For the complete operation of the measuring device, including device-specific commands, device
description (DD) files are available to the user to provide the following operating aids and programs:
!
Note!
If the transmitter is configured via HART, you have to disconnect a circuit for the HART input and
achieve the connection according to å 22 or å 23.
Field Xpert HART Communicator
Selecting device functions with a HART Communicator is a process involving a number of menu
levels and a special HART function matrix.
The HART operating instructions in the carrying case of the HART handheld terminal contain more
detailed information on the device.
"FieldCare" operating program
FieldCare is Endress+Hauser’s FDT-based plant asset management tool and allows the configuration
and diagnosis of intelligent field devices. By using status information, you also have a simple but
effective tool for monitoring devices. The Proline flowmeters are accessed via a service interface or
via the service interface FXA193.
"SIMATIC PDM" operating program (Siemens)
SIMATIC PDM is a standardized, manufacturer-independent tool for the operation, configuration,
maintenance and diagnosis of intelligent field devices.
"AMS" operating program (Emerson Process Management)
AMS (Asset Management Solutions): program for operating and configuring devices.
