NTRODUCTION
This manual provides guidance for the installation, operation, and maintenance of your P+F Multiplexer
2700 and termination board. The solution herein is specifically designed for easy Multiplexer integration with
the Triconex TRICON system. Below is a list of termination boards and the Triconex I/O modules with which
they were designed to interface.
HPTB/32/TR-AI-03
The P+F Multiplexer 2700 will be referred to in this manual as the MUX 2700. All further general references
to the listed termination boards will be simply HPTB. When referring to the combination of a MUX 2700 and
an HPTB, they will be called the HART Interface Solution, or simply HIS.

YSTEM
Your HART Interface Solution interfaces up to 32 field located HART devices. The MUX 2700 is a HART
signal multiplexer unit which allows access to HART communications on existing 4-20mA wiring. It acts as
a gateway device routing communications between the maintenance workstation PC and the HART
devices. The MUX 2700 uses Manchester encoding of the HART protocol for the RS-485 link to the
maintenance workstation PC. To link to each of the HART devices the MUX 2700 communicates using Bell
202 Frequency Shift Keying (FSK). It interrogates each HART device, retrieves device information, and
stores it in an internal database. This information is available to the maintenance workstation software. In
this way, the MUX 2700 gives the user access to each HART device as if connected directly at the device
itself. A maintenance workstation PC can use this information for configuration, maintenance, calibration,
diagnostics, and data access.
The termination board design allows the DCS and field device wiring to be brought together with the MUX to
complete the system. Various HPTB board designs allow interface with different I/O cards and may include
configurable options including fused / filtered signal lines, loop or device powered instrument lines and 4-
20mA or 1-5 VDC signals. HART Interface Solutions are supplied by P+F in several models in order to
allow simple and reliable connection between SMART devices and various DCS systems.

HART O
VERVIEW
HART is an acronym for "Highway Addressable Remote Transducer". The HART protocol makes use of the
Bell 202 FSK standard to superimpose digital signals at a low level on top of the 4-20mA signal. This
enables two-way communication and makes it possible for additional information beyond just the normal
process variable to be communicated to/from a SMART field instrument. The HART protocol allows a host
application (master) to get two or more digital updates per second from a field device. As the digital FSK
signal is phase continuous, there is no interference with the 4-20mA signal.

ANAGEMENT
AMS software provides an easy-to-use means for integrating various device management software
packages into a unified system. AMS operates under the Microsoft® Windows® format. It combines the
various device (or asset) management tasks into an application with a common look-and-feel and
centralized data storage.
AMS provides access to functionality available via the HART communications protocol for any HART device
whose Device Description (DD) is registered with the HART Communication Foundation.
For more information on installation of AMS software, consult the AMS Installation Guide.
