APPENDIX C - HART COMMUNICATION
This chapter gives a detailed information on the supported HART-commands, variables and status
bits present in the E018-P that are required to connect and operate your HART-enabled device.
HART (Highway Addressable Remote Transducer) is an industrial protocol that must be
superimposed on a 4-20mA current loop signal. It is an open standard, and full details about HART
can be obtained through the website of the FieldComm Group (previously HART Communication
Foundation) at www.fieldcommgroup.org.
Device Descriptor
All standard HART configuration items are accessible without any special configuration. To configure
all settings of your E018-P device, your host or communicator must use a specific HART Device
Descriptor (DD), especially designed for the E018-P. These DD’s can be downloaded from the
FieldComm Group website (www.fieldcommgroup.org) or the Fluidwell website (www.fluidwell.com).
