If the bar indicates devices have been found you can select which device to connect by selecting the bar.
This brings up a list box from which to pick your device.
Once you choose a device and press Accept, the box will collapse and the communicator will initiate
connection. Once the device is connected the bar will turn green.
If the poll address range is a single address, and a device is found at that address, the communicator will
immediately initiate connection, and additional polling is terminated. The bar will turn green when the
initialization is complete.
Whenever the bar is green:
It indicates that a device is actively connected to the HART ® network. The communicator does not
continue to poll for other devices. If the green bar is selected the communicator will initiate the online
HART
® menus. If a different device is desired selecting the Restart Poll icon will begin a new search for
devices and the established HART ® connection will be lost.
4.4 Device Specific & Generic HART
®
Communication
The communicator supports a large and growing number of Device Specific DDs (Device Object Files). Visit
www.meriam.com to find a link to the HART ® Communication Foundation’s current library release.
To facilitate communication with HART ® devices that are not yet supported with Device Specific DD files or
that do not require DD files, the communicator includes Generic HART Communication capability. This
allows the user to communicate with any HART
® device using Universal and Common Practice commands to
poll, configure, and maintain HART ® devices. Specific functions supported include most polling, tagging,
device configuration and trim operations for analog outputs. Generic communications do not support Device
Specific commands for higher order HART
® functions. Review the User’s Manual for the HART ® device of
interest for more information on device specific command support.
