HART®Concentrator System
HART-to-MODBUS RTU Converter
Introduction
This is the user’s manual for the Moore Industries
HCS HART® Concentrator System. It contains all of
the information needed to configure, install, operate
and maintain this instrument.
About this Manual
Pay particular attention wherever you see a “Note”,
“Caution” or “WARNING ”.
Note– Information that is helpful for a procedure, con-
dition or operation of the unit.
Caution– Hazardous procedure or condition that
could damage or destroy the unit.
WARNING– Hazardous procedure or condition that
could injure the operator.
The HCS
The HCS HART®Concentrator System converts
a HART digital signal to a serial MODBUS RTU
(RS-485 or RS-232, depending on Output type
ordered) communication protocol. This allows HART
transmitters and valves to interface directly with
MODBUS-based monitoring and control systems.
The HCS uses the following HART commands to
collect its data.
Command 0 Read transmitter unique identifier
Command 3 Read all dynamic variables and current
Command 13 Read tag, descriptor, date
Command 48 Read additional transmitter status
The 3rd generation HCS is now compatible with HART
7 protocol by the release of new HCS firmware v5.2.
This version of the HCS is compatible with HART
5, 6 and 7, however it does not support ALL of the
new features available in HART 6 and 7. Appendix
B provides more details of HART compatibility for all
generations of HCS.

Model and Serial Numbers
Moore Industries uses the model and serial numbers
of our instruments to track information on each unit
that we sell and service. If a problem occurs with
your HCS, check for a tag affixed to the unit listing
these numbers. Supply the Customer Support
representative with this information when calling.
Inputs
The HCS is equipped with one input channel. This
handles up to 16 HART devices in multidrop mode.
In a digital multidrop HART network, up to 16 HART
instruments digitally communicate on the same wires.
The HCS can be set to monitor any or all instruments
and/or valves within the network. Only one MODBUS
address and one communication link is needed to
send the process and diagnostic data from up to 16
HART devices to a MODBUS host.
The instrument is equipped with a READY LED to
indicate the health of the unit and an INPUT LED
to indicate status of HART communication to the
attached HART devices.
Outputs
The HCS offers a standard RS-485 or RS-232 port
(depending on Output type ordered) that supports the
MODBUS RTU protocol.
MB232
Allows for standard MODBUS RTU protocol interface
over a RS-232 port.
MB485
Allows for standard MODBUS RTU protocol interface
over a RS-485 port.
TX Power Supply
A transmitter excitation power supply (regulated
23.2Vdc ±3%@24mA, maximum) is standard on the
HCS. You may access it at the terminals shown in
Figure 3.
