Description
The MACX MCR-S-MUX HART multiplexer is used for the
digital connection of up to 32 HART-capable field devices to
a PC.
HART field devices are connected in point-to-point mode
via a HART connection board and communicate with the
HART multiplexer via the HART protocol. These HART
signals are superimposed on the analog standardized
signals (4 ... 20 mA) of the process variables.
Conformance
The MACX MCR-S-MUX HART multiplexer meets the
following standards and directives:
– Directive 94/9/EC
– EN 61326
– VDE 0110
– HART Field Communication Protocol Rev. 6.0
The HART multiplexer communicates with a connected PC
via an RS-485 bus.
The configuration and diagnostics of the connected HART
field devices are implemented by the HART/OPC server or
standard software tools, such as Cornerstone, AMS
(Version 6.2 or later), PDM, PRM, FieldCare or PACTware.
WARNING: Risk of electric shock
Observe the safety notes on page 4.

Safety notes
WARNING: Risk of electric shock
Please observe the following notes during installation and operation:
– Observe all national assembly and installation regulations (e.g., EN 60079-14), national safety and accident
prevention regulations, generally recognized technical regulations, as well as the safety notes in the operating
instructions.
– Install the HART multiplexer outside potentially explosive areas.
– Use the module for its intended purpose, i.e., only for its approved application (see page 1).
– Incorrect or improper use or failure to observe the notes in the operating instructions invalidates the warranty.
– Modifications and changes to the module are not permitted.
– The module must only be installed and operated when in an undamaged, dry, and clean state.

The assignment of the connection terminal blocks is shown
in the block diagram. The module can be snapped onto all
35 mm DIN rails according to EN 60715.
• Push the module onto the DIN rail from below (A). Push
the module from the front toward the mounting surface
until it engages with a click (B).
• Pull the base latch up using a screwdriver, needle-nose
pliers or similar (C). Pull the top edge of the module
away from the mounting surface and pull the module
diagonally downward away from the DIN rail (D).

Communication with field devices
An RS-485 bus is not required for communication
with field devices.
Once scanning is complete, the HART multiplexer
establishes communication with the HART field devices that
are found.
The "HART-Tx" and "HART-Rx" LEDs light up alternately.
If no field devices are found when the HART multiplexer is
started, both LEDs remain off.
If modules are added later, they must be located and added
using the PC software (e.g., in Cornerstone using "Learn" or
"Add instrument").
HART communication is only possible if the control circuit
resistance is between 230 Ω and 600 Ω. An additional
resistor may be required. 250 Ω is sufficient in most cases.

The following components are required:
– Field device
HART-capable
Ex-certified, if necessary
– Signal converter
HART-penetrable
Ex-certified, if necessary, for explosion protection
through energy limitation (EX-i) of the circuit for the field
device. For example, a repeater power supply that
supplies the field device and forwards the process
signal (4 ... 20 mA) with electrical isolation to a
controller.
– If required, a suitable terminal block in order to route
the signal to the connection board.
– HART connection board
Here, a maximum of 16 channels are connected per
board. An FLK plug can be used to extend this to
32 channels by adding a board.
– HART multiplexer
Accepts the HART signal, which was previously
decoupled capacitively, and forwards it via an RS-485
interface.
A maximum of 32 field devices in succession can
therefore communicate bidirectionally via a HART
multiplexer.
The flat-ribbon cable for connection to the connection
board is supplied as standard.
– Interface converter, RS-485 to RS-232
– If necessary, a resistor for the signal cable
A termination resistor may be required in the signal
cable. According to the HART specification, a
resistance value of between 230 and 600 Ω is required
for the transmission of the HART signal.
– Power supply
The converter, connection board, signal converter, and,
if necessary, the field device must be supplied with
24 V.
Software
The following may be required:
– Standard software tools, such as Cornerstone, AMS
(Version 6.2 or later), PDM, PRM, FieldCare or
PACTware
– HART OPC server (HCF server - the program can be
purchased from the HCF (HART Communication
Foundation))

Interface converter, RS-485 to RS-232 or FL COMSERVER
MACX MCR-S-MUX HART multiplexer with two PI-EX-MB-S/16-01-2/D-SUB (2 x 16 channels) HART
connection boards and PSM-ME-RS232/RS485-P interface converter or FL COMSERVER

MACX MCR-S-MUX
The following components are required:
– Field device
HART-capable
Ex-certified, if necessary
– Signal converter
HART-penetrable
Ex-certified, if necessary, for explosion protection
through energy limitation (EX-i) of the circuit for the field
device. For example, a repeater power supply that
supplies the field device and forwards the process
signal (4 ... 20 mA) with electrical isolation to a
controller.
– If required, a suitable terminal block in order to route
the signal to the connection board.
– HART connection board, PI-EX-MB-S/16-01-2/DSUB
Here, a maximum of 16 channels are connected per
board. An FLK plug can be used to extend this to 32
channels by adding a board.
– HART multiplexer
Accepts the HART signal, which was previously
decoupled capacitively, and forwards it via an RS-485
interface.
A maximum of 32 field devices in succession can
therefore communicate bidirectionally via a HART
multiplexer.
The flat-ribbon cable for connection to the connection
board is supplied as standard.
– Interface converter, RS-485 to RS-232 or
FL COMSERVER
– Ethernet cable (for FL COMSERVER only)
– If necessary, a resistor for the signal cable
A termination resistor may be required in the signal
cable. According to the HART specification, a
resistance value of between 230 and 600 Ω is required
for the transmission of the HART signal.
– Power supply
The converter, connection board, signal converter, and,
if necessary, the field device must be supplied with
24 V.

Repair and maintenance
We recommend that you only allow us to repair our modules. In exceptional cases, repairs can also be made by another
approved body.
The modules are maintenance free.
Troubleshooting
Error detection
"PWR" LED off
Possible error cause
Error removal
Auxiliary voltage failure or module fuse faulty Check auxiliary voltage supply.
"PWR" LED flashing
Internal module error
"ERR" LED flashes briefly
No HART field device found
"HART" LEDs off
No HART field device found
"RS485" LEDs off
No RS-485 bus connected.
RS-485 interface not active.
If fuse is faulty, return the module for repair.
Switch module off/on. If LED keeps flashing,
return the module for repair.
Connect HART field device and check
connection.
Connect HART field device and check
connection.
Connect RS-485 interface and check
connection.
If the approaches described prove unsuccessful, please contact our nearest sales center. For a quick response, make sure
you have the following information to hand:
– Type and serial number
– Purchase data
– Error description
– Application (especially input/output circuit)
