STBAHI8321KC HART Multiplexer
Presentation
Highway Addressable Remote Transducer Protocol (HART) is the global standard
for sending and receiving digital information across analog wires between smart
devices and a control or monitoring system. The standard is controlled by the HART
Communications Foundation.
 Most control systems can only monitor or control a single eld instrument’s
variable via the analog signal. This solution allows access via Ethernet to the many
additional variables and parameters of HART smart instruments.
 The HART multiplexer can assist in the Conguration, Maintenance and
Diagnosis of remote HART eld instruments.
 This solution allows users to benet from preventative maintenance information
provided by HART smart instruments. This can help the move to cost saving
Predictive Maintenance.
The STBAHI8321, when used with a HART enabled NIM (STBNIP2311 version 4.01
and above), creates a HART multiplexer solution allowing remote systems to obtain
digital data over Ethernet from HART instruments (sensor or actuator devices) on
4-20mA current loops. HART data such as Process Values and diagnostic
information can be read by PCs, HMIs.
 Provides access to HART-enabled intelligent eld instruments.
 This modular solution is very expandable. A HART multiplexer island consists of
1..8 HART modules. This gives 4 to 32 HART devices. (1 HART module = 4 channels
= 4 HART devices)
 Allows PLCs and SCADA to access data from HART instruments using MODBUS
commands over Ethernet.
 HART data can also be monitored on the multiplexer’s web pages.
 Transparently attaches to the 4-20mA current loop between controller and HART
device.
 Reading or writing the instrument’s analog signal is possible via optional STB IO
modules on the STB island or via a controller’s analog module.
 Supports HART Protocol versions v5,v6 and v7
 Can be congured by Advantys Conguration Software.
 DTM support allows conguration and use with FDT based host applications,
such as Endress+Hauser FieldCare, PACTware and Unity Pro. (1)
