Description
© PHOENIX CONTACT - 2012-05-03
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.
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.
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
WARNING: Risk of electric shock
Observe the safety notes on page 4.
Make sure you always use the latest documentation.

Description
The HART transfer board is used to operate the MACX MCR-S-MUX HART
multiplexer. The signals from the HART-capable signal converters are applied
to the terminal strip of the transfer board where they are then transmitted to the
multiplexer via an FLK.
Interface converter, for conversion from RS-232 to RS-422 and RS-485, with
electrical isolation, 2 channels, DIN-rail mountable
Repeater, for electrical isolation and increasing the range in RS-485 2-wire
bus systems, 3-way isolation, DIN-rail mountable (required if there are more
than 32 multiplexers on one interface)
Ex-i motherboard for accommodating 16 x PI-Ex supply, input or output
isolating amplifier modules. With interface for connecting to HART multiplexer
and D-SUB pin strip for connecting the analog signals to the control system
level.
FL COMSERVER BASIC..., serial devices server to convert a serial RS-232/
422/485 interface to Ethernet, supports TCP, UDP applications, incl. CD-ROM
with Com Port Redirector Software and user documentation (PDF).

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.

Installation
WARNING: Danger if installed incorrectly
Install the HART multiplexer outside potentially
explosive areas.
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).
