to avoid property damage.
Depending on the risk level, the warning messages are displayed in descending order
as follows:
Informative Symbols
Action
This symbol indicates a paragraph with instructions. You are prompted to perform an action
or a sequence of actions.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and plants,
or result in their complete failure.

2 Product Specifications
2.1 Device Versions
This manual describes the following devices:
• HART multiplexer master KFD2-HMM-16, hereinafter referred to as the multiplexer master
• HART multiplexer slave KFD0-HMS-16, hereinafter referred to as the multiplexer slave
2.2 Function
The HART multiplexer system consists of one HART multiplexer master KFD2-HMM-16 and
several HART multiplexer slaves KFD0-HMS-16. The HART multiplexer system is used
to establish a HART connection to analog field devices and thereby maintain the conventional
analog 4 mA to 20 mA circuits. The devices of the HART multiplexer system act as gateways
between the field devices and the control side.
The devices of the HART multiplexer system can be used in the Zone 2 hazardous area or
in the non-hazardous area. The devices are supplied with 24 VDC. The devices are connected
to a maintenance station or the process control system via an RS-485 interface.
The supply, the analog signals, and the RS-485 interface are galvanically isolated from each
other. The individual HART channels are decoupled. This does not affect
the 4 mA to 20 mA signal.
Using the configuration software, you can search for available field devices automatically and
query the HART variables of the field devices automatically.

Product Specifications
2.2.1 HART Multiplexer Master KFD2-HMM-16
In addition to the master unit, the multiplexer master has an integrated slave unit. A maximum
of 16 field devices can be connected to this slave unit. If more than 16 field devices have
to be connected, a maximum of 15 additional HART multiplexer slaves KFD0-HMS-16 can
be connected to the multiplexer master. This enables a maximum of 256 analog field devices
to be connected to the HART multiplexer system.
The device is supplied with power via the Power Rail or via terminals.
The device is connected to a maintenance station via the RS-485 interface. You can connect
additional participants via an additional RS-485 interface. The transfer rate is max.
57600 baud.
The device is connected to the multiplexer slaves via a 14-pin ribbon cable. The device has
a 14-pin IDC socket on the bottom of the device for this purpose.
The device is connected to the termination board via a 26-pin ribbon cable. The device has
a 26-pin IDC socket on the front of the device for this purpose.
The device can be used as a primary or secondary master.
The device address and the transfer rate are set via DIP switch.

2.2.2 HART Multiplexer Slave KFD0-HMS-16
A maximum of 16 analog field devices can be connected to the multiplexer slave. The device
can only be used in conjunction with the HART multiplexer master KFD2-HMM-16.
The device is supplied with power by the multiplexer master via the 14-pin ribbon cable.
The device is connected with the multiplexer master and additional multiplexer slaves
via a 14-pin ribbon cable. The device has a 14-pin IDC socket on the bottom of the device for
this purpose.
The device is connected to the termination board via a 26-pin ribbon cable.
The device has a 26-pin IDC socket on the front of the device for this purpose.
The device address is set using a rotary switch. You can assign addresses 1 to 15.
The address 0 is reserved for the multiplexer master and may therefore not be used. If several
multiplexer slaves are connected to the multiplexer master, different addresses must
be assigned. The sequence is irrelevant.

System Description
3 System Description
3.1 The Basic Principles of HART Communication
The HART protocol is supported by many conventional4mAto20mAfielddevicesthatuseit
to enable digital communication for configuration and maintenance purposes. Many of the
device parameters, and the measured value itself, can be digitally transferred to and from
the device. This digital communication runs in parallel to the 4 mA to 20 mA signal on the same
line. This is enabled via current modulation, which is superimposed on the desired signal.
Figure 3.1
The high-frequency HART signal consists of the sine frequencies 1200 Hz and 2200 Hz.
The average value of the signal is 0 and can therefore be filtered through the standard circuit of
the analog input. This does not affect the analog signal.
The HART protocol is a master-slave protocol. This means that a field device responds only
when it is addressed. Burst mode is an exception. The message duration is a few hundred
milliseconds, meaning that two to three messages can be transferred per second.
The HART commands are divided into 3 groups:
• Universal commands
These commands must be supported by all field devices.
• Common practice commands
These commands correspond to common practice and are suitable for many field devices.
• Device-specific commands
These commands are only suitable for certain field devices.
All three types of commands are used in the HART multiplexer system. This document
includes a list of commands. See chapter 9.1.
