2 OVERVIEW OF HART COMMUNICATOR (HARTCOM-W2)
Field devices such as flow, pressure, level, temperature transmitters, and valve positioners provide the physical
connection to the process. These devices allow the control system to monitor and manipulate process conditions.
HART devices maintain a real-time database of process, configuration, identification, and diagnostic information.
This information can be accessed using the HART Field Communications Protocol.
HART devices are capable of providing functions and features far beyond the basic task of providing a process input
or accepting a control output to manipulate process conditions. Many HART compatible device manufactures create
a DD (Device Description) describing all of these functions and features specific to that device. The DD also provides
information essential to the successful configuration and calibration of the device.
HART Communicator (HARTCOM-W2) uses thes
e DD’s to access the data stored in a device, providing full
configuration and setup support for all
registered HART DD’s.
HART Communicator (HARTCOM-W2) accesses and presents field device data based solely on its DD. No other files,
information or custom drivers are required to view and modify
field device parameters. Using the device’s DD,
HART
Communicator (HARTCOM-W2) can perform various tests to verify the proper operation of the HART device.
Currently there are three recognised categories of HART devices:
1)
The original 4-20mA wired HART device
2)
HART-IP devices (i.e. Remote I/Os and Multiplexers)
3)
Wireless
HART devices
HART Communicator HARTCOM-W2 supports all three technologies allowing you to configure HART devices whether
they are connected via HART Modem, HART-IP device, or
Wireless
HART Gateway.
