HART Multiplexer System KFD*-HM*-16
System Description
Maintenance Station
A computer is often used as a maintenance station to operate and maintain the
HART multiplexer system. The computer is used to fulfill parameterization functions or logging
functions independently of the process control system. For this computer, operating software
that fulfills the required purpose is available from various manufacturers. See chapter 3.3.
However, in some cases, no computer is used as a maintenance station. Instead,
the process control system communicates with the field devices directly via an
RS-485 interface using the HART multiplexer system. The low speed of the
HART communication imposes limitations on this method of operation.
3.3 Integration into Operating Software
The full functionality of the HART multiplexer system unfolds through the integration into
modern asset management systems such as PACTware (open source), SIMATIC PDM
(Siemens), AMS (Fisher-Rosemount), Cornerstone (Applied System Technologies), and Valve
Manager (Neles Automation). These operating tools integrate the device functions of the
devices in the multiplexer system into a standardized interface and convenient operation in
the form of menu commands. However, the representation and designation of the functions in
the individual operating tools may vary greatly. A representation that is valid generally is not
possible at this point.
Information regarding the configuration, parameterization, operation, and diagnostic options
of the HART multiplexer system can be found in the manual "Installation and Configuration
Device Type Manager (DTM)".
3.4 System Structure
The field devices and the devices of the HART multiplexer system are connected to
the process control system using termination boards. The following chapters describe
three basic connection options. These connection options serve as examples as there are
many other connection options.
The following accessories are available for the HART multiplexer system:
•
14-pin ribbon cable K-HM14 for connecting the multiplexer master with the
multiplexer slaves.
• 26-pin ribbon cable K-HM26 for connecting the multiplexer master or the multiplexer slave
with the termination board.
• Interface converter in different variants depending on the available interfaces
• Cordset for the connection between the termination board and the process control system.
This cordset is available in different variants depending on the available interfaces and
the control system manufacturer.
Note!
For further information about the connection layout of the termination boards used, see the
corresponding datasheets.
