Product description
3.2 Operating principle of the device
3.2.1 PROFIBUS DP principle
PROFIBUS DP is an open communication protocol in accordance with EN 50)170-2 for
deployment in the entire field. It enables cyclic and acyclic data exchange between the
control, the PROFIBUS DP master and connected components, the PROFIBUS DP slaves.
The PROFIBUS DP master communicates with the PROFIBUS DP slaves via “telegrams”.
Various telegrams are defined in the PROFIBUS DP, e.g. for requesting status information
(cyclic communication) or for transmitting configuration data (acyclic communication).
The UE 4100 is physically connected to the PROFIBUS DP by a shielded two-wire copper
conductor using IP 67 connection technology.
PROFIsafe
PROFIsafe is an extension of the PROFIBUS DP protocol for safety technology. In the case
of PROFIsafe, the communication between the PROFIsafe users (“failsafe DP standard
slaves”) and the PROFIsafe master is protected against transmission errors and changes.
The UE 4100 is a PROFIsafe device according to “PROFIsafe — Profile for Safety Techno-
logy”, V1.20 10/2002. This is why the UE 4100 constantly expects a PROFIsafe master
and does not establish any communications with unsafe PROFIBUS DP masters.
You can find more information about PROFIBUS and PROFIsafe on the Internet at
www.profibus.com.
3.2.2 The principle of the bus node
Bus node UE 4100 is a PROFIsafe slave. It collects the electrical signals from the compo-
nents connected to the UE 4100 to form what is known as a process image. It sends this
to the PROFIsafe master in the form of a PROFIsafe telegram. The PROFIsafe master
copies the input data of the from the PROFIsafe telegram into the FPLC process image.
The FPLC evaluates the input process image. It then places the calculated output values
into the output process image. The PROFIsafe master transmits these output data to the
bus nodes in a PROFIsafe telegram.

$switching a non-safety-related output.
$addressing specific functions of the connected devices.
The following advantages are to be had by using bus node UE 4100:
$cost-savings on purchase: The components to be connected do not have to have their
own PROFIBUS slave.
$improved use of PROFIBUS capacity: Only one PROFIBUS slave is necessary for several
components of an application.
$integration of all the functions of present and future SICK safety components with an
SDL interface without loss of functionality
$lower cost of wiring on the PROFIBUS side as several components are connected as a
PROFIBUS user

3.5 Configurable functions
This section describes the functions of the bus node UE 4100 which are selectable via
software. Chapter 6 “Examples of circuits” on page 32 describes several typical applica-
tions that you can realise with the aid of the functions described below.
Test the protective device after any changes!
Changes to the configuration of the devices can degrade the protective function. After eve-
ry change to the configuration you must therefore check the effectiveness of the protective
device. To this end, please observe the notes in chapter 7.3.4 “General acceptance by the
bus node” on page 37.
The person who makes the change is also responsible for the correct protective function of
the device. When making configuration changes, please always use the password hierar-

3.5.1 Functions of the field-signal connections
The field-signal connections are suitable for connecting:
$safety components fitted with contacts, e.g. an emergency stop button or a safety door
switch with or without a locking device
$components fitted with contacts, e.g. control switches or key-operated switches
$switching outputs (OSSDs) of active safety sensors, e.g. SICK safety light curtain FGS or
detection laser scanner PLS
$active sensors, e.g. single-beam photoelectric switches, muting devices
It is only permitted to connect a muting lamp to channel A of field-signal connections 7
and 8, as only their outputs have fault monitoring.
Make regular checks of the components fitted with contacts!
When connecting components with contacts to the bus node, which are only occasionally
activated, you must take organisational measures to safeguard that any fault in these
components will be detected, e.g. by means of monthly manual checks (corresponds to
Control category 4).
Do not use the outputs of the field-signal connections for components that are not
essential for safety!
The outputs of the field-signal connections are not permitted to be used for switching off
agents that may jeopardize the situation. This is why you may only use the outputs to
control lamps, locking devices, etc. or to supply sensors, etc.
A cut-off signal at the input must be available for at least two PROFIBUS cycles!
You must safeguard this as early as the design phase by selecting components that are
suitable for this. A cut-off signal that is available from one sensor on the field-signal input
for only one cycle will not be detected by the FPLC under certain circumstances.
Every field-signal connection on the UE 4100 has two safe inputs and two standard out-
puts. You can configure these inputs and outputs in different ways:
$Single-channel: The two channels of the field-signal connection have entirely separate
configurations.
$Two-channel: Channels A and B of the field-signal connections are interdependent.
Details can be found in chapter 3.5.2 “Two-channel selection of the field-signal
connections” on page 19ff.

In addition to the type of connection, you can also configure the following parameters for
an input/output:
Parameter Description
Output (Out A,

You can configure one of the following signals on the output:
$Static 24 V, e.g. as voltage supply
$Static 0 V (Out)
$FPLC output signal
$test signal for safety components fitted with contacts, e.g. an
emergency stop button
$field-signal connections 7 and 8 only: monitoring a muting lamp
$signal bit of an SDL-compatible component on the SDL connection (bit
set = 24 V)
Safety input
(In A, In B)
You can pass on the input signal as follows:
$to the FPLC safety input
$to the safety input of a device connected to the SDL connection2)
Input delay
[ms]
Delay (5–90 ms) between the detection of the signal change and the
effective evaluation of the input signal
Application: Several unintentional brief signal changes occur when
opening or closing a component fitted with contacts as the result of the
bouncing. In order for the bounce of the components fitted with con-
tacts not to influence the evaluation in the bus node, you must set the
input delay time longer than the bounce time of the components fitted
with contacts.
If you read in a contact without bounce time via the safety input, e.g.
the switching output (OSSD) of a light grid/light curtain, you must set
the input delay to Inactive in order to safeguard immediate signal
processing.
Check the response time of the protective device!
The configured input delays increase the response time of the protective device. You must
take these times into account when calculating the response time of the protective device
(see chapter 10.2 “Response time” on page 54).
Deactivate unused sections of the field-signal connections!
$If you are not using an input of a field-signal connection, you must configure the safety
input of the corresponding channel with the aid of the CDS to Off.
$If you are not using an output of a field-signal connection, you must configure the output
of the corresponding channel to Static off.
If a signal is still present on an input or output configured in this way, the bus node detects
this as an error status.

Product description
The electrical connection to the field-signal connections is described in chapter 5.3 “Field-
signal connections M12)×)5 + FE” of this document on page 29. Examples can be found in
chapter 6 “Examples of circuits” on page 32.
Routing
When configuring the outputs of a field-signal connection as an output signal, you must
establish the source of these signals in the bus node. This setting is called Routing.
SICK offers special function packages for the bus nodes in connection with SICK safety
components on the SDL connection. With the appropriate function package, you can …
$route field signals to a particular signal bit of a device on the SDL connection, i.e. to a
connected ESPE.
$pick up a signal bit from a device on one of the SDL connections and place it on an
output signal, e.g. the Reset required signal bit of an ESPE.
If you route the input of a field-signal connection directly onto the signal bit of an SDL
connection, the FPLC can no longer modify this signal bit of the SDL connection.
The operating instructions of the function package contain information about the signal
bits of the corresponding device that can be routed.
Test-signal allocation
In the case of test signals, you must establish which bus-node input is to expect the test
signals when the device is operating. You will usually use the input of the same channel.
However, you can also use the input of a different field-signal connection (e.g. when con-
necting a operating mode selector switch with more than two settings).
3.5.2 Two-channel selection of the field-signal connections
In the case of two-channel selection, both input and output channels A and B of the field-
signal connection are interdependent. Possible selections:
$equivalent: normally open/normally open or normally closed/normally closed
$complementary: normally open/normally closed or normally closed/normally open
(cf. Tab. 4).
$In the case of the two-channel selection, the bus node transfers the result of the evalu-
ation of both inputs in the status bit of input A.
$If the input signal changes from the active status into a different one, for safety reasons
the bus node immediately switches the corresponding input in the process image to 0
(cf. Tab. 4).
Monitoring the discrepancy time
The discrepancy time is the maximum period in the case of the two-channel selection,
within which both the inputs of the field-signal connection may have an inadmissible status
without the bus node detecting an error. Discrepancy time monitoring commences when
the status of an input changes. The bus node detects an error when both inputs of the
field-signal connection do not have the same or opposite statuses at the end of the discre-
pancy time.
If you have set the discrepancy time to Inactive, the bus node does not generate an error
when the status of only one input changes.

$For the duration of the set discrepancy time, the bus node does not transfer any other
signal changes of the field-signal connection to the PROFIsafe telegram, nor does it route
this to other connections.
$When the input status changes from Inactive to Active, the discrepancy time delays the
change in the process image.
$In order to delete a discrepancy-time error, you must reset both inputs to their Inactive
status.
3.5.3 Functions of the SDL connection
The SDL connection contains the safe SICK device communication (EFI), two inputs for
OSSDs and the voltage supply for the sensor. The connections are suitable e.g. for the
senders and receivers of a SICK safety light curtain. You can also connect devices to the
SDL connection that do not have safe SICK device communications, if these devices have
tested semiconductor switching outputs (OSSDs).
$If you connect devices to the SDL connections with safe SICK device communication, the
bus node makes the device information available in two different ways:
–for the FPLC in the PROFIsafe telegram
–for devices on the field-signal connections as signal sources (“routing”)
Bus node UE 4150 can read the data of the safe SICK device communication. In order to
write process data to the devices via safe SICK device communication, you require the
UE 4155.
$If you connect devices with OSSDs that do not have safe SICK device communication,
the bus node only makes the information from the OSSDs available in the PROFIsafe
telegram.
