Using a field multiplexer in the field multiplexer system
5981_en_06 PHOENIX CONTACT 11
2 Using a field multiplexer in the field multiplexer system
The field multiplexer is a simple system for the transmission of signals between remote
stations. It has a modular design, and saves on conventional parallel cabling.
A field multiplexer system is set up using two identical field multiplexers. The multiplexers
are electrically linked over a 2-wire cable and may transmit digital and analog signals over
a distance of up to 12 km.
Data can also be transmitted over fiber optics, telephone lines, Bluetooth or Ethernet. In
these cases other maximum distances are possible (see Section “Transmission media” on
page 41).
2.1 Arrangement of a field multiplexer system
The field multiplexer and the Inline I/O terminals connected to it form a station. A field
multiplexer system consists of two stations. The two stations must be arranged in such a
way that each input terminal is assigned to an output terminal on the other side, and vice
versa (complementary arrangement, see Figure 2-1).
In addition to the complementary arrangement of I/O terminals in each station and its
counterpart, a distinction must be made between the active (master) and the passive (slave)
field multiplexer station. This is done by inserting a jumper into one of the stations, which
thereby becomes the master. Further configuration settings are not required.
Up to 32 Inline I/O terminals can be connected to a field multiplexer station simply by
mounting them next to one another.
The intelligent wiring method used by Inline terminals enables the field multiplexer station to
be created quickly and easily, since, for example, time-consuming wiring of the terminal
power supply is not required. It is only necessary for the power supply units integrated in the
field multiplexers to be supplied with 24 V DC on the input side. They generate the operating
voltage required for the field multiplexer and the connected Inline I/O terminals.
Figure 2-1 Complementary arrangement of I/O terminals
5981C002

IB IL 24 MUX MA-PAC
12 PHOENIX CONTACT 5981_en_06
2.2 Data transmission
A maximum of 512 I/O data can be transmitted by each station. This corresponds to a
maximum of 512 digital or 32 analog inputs and/or outputs. Digital and analog signals may
also be mixed.
The transmission time for all I/O data depends on the number of inputs and outputs to be
transmitted, but is a maximum of 1 s. In practice, data is transmitted considerably faster (see
also “Transmission time” on page 13).
The field multiplexer transmits the signals that are present in parallel at the I/O terminals
serially along the cable. At the other end of the cable, the signals are output again through
the complementary I/O terminals in the opposite station.
Data is transmitted between two field multiplexer stations over a 2-wire copper cable.
RS-485 transmission reduces the effect of electromagnetic interference on the signals. A
maximum distance of 12 km may be covered.
Data can also be transmitted over fiber optics, telephone lines, Bluetooth or Ethernet. In this
case, use additional interface converters from Phoenix Contact and configure the field
multiplexers and converters accordingly (see Section “Technical appendix: The field
multiplexer with different transmission media” on page 67).
fiber-optic transmission is configured using a jumper on the first Inline connector.
The maximum distance depends on the type of cable selected, as well as on EMC
environmental conditions.

Using a field multiplexer in the field multiplexer system
5981_en_06 PHOENIX CONTACT 13
2.3 Transmission time
The maximum time required for data transmission depends on the type of transmission
medium that has been selected, and can be calculated using the formula below.
When operating field multiplexer systems over copper cables, the following formula applies
If the field multiplexer is operated over fiber optics, this formula applies
The number of bytes to be transmitted depends on the particular terminal:
The transmission time typically varies within the following limits:
Only the I/O terminals from one of the two stations have to be taken into consideration
when making the calculation.
tup = n * 6.8 ms/byte + 78 ms + m
tup = Update time for field multiplexer I/O data
n = Number of bytes to be transmitted
m = Delay when using different transmission media
Copper m = 0 ms
Telephone line m = 20 ms
Ethernet cable m = 0 ms
Bluetooth connection m = 40 ms
tup = n * 1.37 ms/byte + 10 ms
Both formulas are valid for worst case scenarios. Transmission is usually faster.

2.4 Diagnostics
LEDs provide station diagnostics on the field multiplexer and the Inline I/O terminals. An
integrated alarm relay permits alarms or warning lamps to be connected locally.
2.5 Additional system components
The field multiplexer system is completed by additional system components from the
Phoenix Contact product range (see Section “Accessories: Additional system components”
on page 66).
2.6 Number of devices in a field multiplexer station
The maximum number of devices that can be connected to a field multiplexer is determined
by the following system specifications:
1Up to 32 devices can be connected to a field multiplexer.
2A maximum of 512 digital or 32 analog signals can be transmitted (even mixed; each
analog channel is treated like a 16-bit digital terminal).
3The field multiplexer can supply a maximum current of 2 A at 7.5 V DC in the logic area.
4The field multiplexer can supply a maximum current of 0.5 A at 24 V DC to analog
terminals.
5The maximum current for the I/O supply is 8 A at US, UMand GND (total current US+
UM).
Please refer to the IL SYS INST UM E user manual for detailed information on the
individual circuits within an Inline station, which also apply for a field multiplexer station.
ACHTUNG: Overload in the event of configuration errors
Observe the current consumption of each device at the individual potential jumpers when
configuring an field multiplexer station. It can be found in every terminal-specific data
sheet.
To determine the maximum number of terminals, add up the current consumption of the
connected I/O terminals.
If the limit value is reached at one of the potential jumpers, a new appropriate power
terminal must be used.
ACHTUNG: Malfunction or overload in the event of configuration errors
The permissible number of devices that can be connected depends on the specific station
arrangement. None of the system specifications given above must be exceeded.

3 Description of the field multiplexer
3.1 General description
Functions The field multiplexer
– forms the head of an field multiplexer station. All the necessary Inline I/O terminals are
connected to it.
– configures the station and manages data exchange with the opposite station over a
remote bus cable.
– supplies power to the connected I/O terminals.
The field multiplexer generates the logic voltage UL for all connected devices from the
supplied supply voltage UMUX as well as the supply voltage UANA for the connected
analog terminals.
Indicators See Section “Diagnostic indicators” on page 17.
Connections See Section “Terminal point assignment” on page 18.
Connection method The field multiplexer is suitable for the connection of copper cables.
Connect cables with diameters of 0.08 mm2through 1.5 mm2(AWG 24 - 16) to the spring-
clamp connections of the Inline connectors.
In order to implement data transmission over other transmission media, additional interface
converters from Phoenix Contact must be used (see Section “Transmission media” on
page 41 or Section “Technical appendix: The field multiplexer with different transmission
media” on page 67).
Protection The field multiplexer has protection against polarity reversal and excess voltage on UMUX.
Potential and data routing The potential and data routing of the field multiplexer station begins at the field multiplexer.
Connection to functional
earth ground (FE)
If the remote bus cable is shielded, the shield is internally connected through a capacitor to
FE.
In the terminal, there is a capacitive connection of UMUX, UM, US, and GND to FE.
Please refer to the IL SYS INST UM E user manual for information on the individual circuits
within an Inline station, which also apply for a field multiplexer station.
Please refer to the IL SYS INST UM E user manual for detailed information on the
individual jumpers as well as on the maximum capacity of the jumper contacts.

Grounding The field multiplexer is grounded when it is snapped onto the grounded DIN rail via the FE
spring on the bottom of the terminal. This spring is connected to the potential jumper FE and
to the terminal points for an FE connection (see “Required additional grounding”).
Required additional
grounding
Ground the field multiplexer additionally through the FE connection to ensure reliable
grounding of the station even if the FE spring is dirty or damaged. Connect the terminal
points for the FE connection to a grounded PE terminal.
