-Protocol
Endura AZ20 transmitters are HART-compatible, factory-calibrated devices. HART-Protocol enables
simultaneous indication of process variables and digital communication. The 4 to 20 mA current output
signal transmits process information and the digital signal is used for bi-directional communication. The
analog process value output enables analog indicators, recorders and controllers to be used, while the
simultaneous digital communication uses HART-Protocol.
7.1 Hardware and Software Requirements
Item
Description
Device Manager
(Hardware)
Install a HART modem (FS
K
Frequency Shift
K
eyed-Modem) for
HART-Communication when connecting to a PC.
The HART-Modem converts the analog 4 to 20 mA signal into a digital
output signal (Bell Standard 202) and connects to the PC using a USB
(or RS232C) connector.
Alternatively, a hand-held terminal can be used (see below).
Compatible
Management Software
Management software required to communicate with
HART-compatible devices using 'Universal' and 'Common Practice'
commands.
Hand-held Terminal
The transmitter can be accessed and configured using a compatible
hand-held terminal (such as the ABB Mobility DHH801-MFC or
equivalent – see Fig. 7.1, page 69).
Transmitter connection is made in parallel with the 4 to 20 mA current
output – see Section 4.8, page 21,
Current Output
(4 to 20 mA) for
terminal connection details.
