Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

DI 8xNAMUR HF parameters
The following table lists the configurable parameters. The effective range of the configurable
parameters depends on the type of configuration. The following configurations are possible:
●Distributed operation on PROFINET IO in an ET 200SP system
●Distributed operation with PROFIBUS DP in an ET 200SP system
When assigning parameters in the user program, use the "WRREC" instruction to transfer
the parameters to the module using data records (refer to the section Parameter assignment

Changing parameter settings and effects on the technology functions
Reconfiguring a technology function resets its responses. Reconfiguring one technology
function has no effect on other technology functions. Exception: Signal inversion and chatter
monitoring, because an additional edge change is generated when signal inversion is
disabled/enabled.

DI 8xNAMUR HF digital input module (6ES7131-6TF00-0CA0)
Manual, 02/2014, A5E03894478-01 13
Technology functions
All technology functions, such as
●Pulse stretching
●Chatter monitoring
●Changeover errors
●Hardware interrupts
are executed only when there is an error-free signal (QI = 1). In other words, there is no
diagnostics information on the channel (see also section Address space (Page 18)).
4.2
Explanation of parameters
Diagnostics: Missing supply voltage L+
The diagnostics alarm is enabled for missing or insufficient supply voltage L+.
Tip: To avoid a diagnostics overload, you should only enable "Diagnostics: Missing supply
voltage" for an active channel.
Diagnostics: Short-circuit to ground
The diagnostics alarm is enabled if there is a short-circuit of the sensor supply to ground.
"Short-circuit to ground" diagnostics is available with the following sensor setting:
●NAMUR sensor
●NAMUR changeover contact
Diagnostics: Wire break
The diagnostics alarm is enabled if the line to the sensor is interrupted.
"Wire break" diagnostics is available with the following sensor setting:
●NAMUR sensor
●Single contact with 10 kΩ
●NAMUR changeover contact
●Changeover contact with 10 kΩ

14 Manual, 02/2014, A5E03894478-01
Diagnostics: Changeover error
The diagnostics alarm is enabled when a changeover error occurs.
"Changeover error" diagnostics is available with the following sensor setting:
●NAMUR changeover contact
●Changeover contact, unconnected
●Changeover contact with 10 kΩ
Diagnostics: Chatter error
The diagnostics alarm is enabled when a chatter error occurs.
Chatter monitoring is a process control function for digital input signals. It detects and reports
signal changes that are unexpected in process engineering, for example when an input
signal fluctuates too often between "0" and "1". If signal characteristics like these occur, it is
a sign that the sensors are faulty or that there are instabilities from a process engineering
viewpoint.
Chatter monitoring: Monitoring window
Chatter monitoring: Setting of the monitoring window
Each input channel has a configurable monitoring window. The monitoring window is started
the first time the input signal changes. If the input signal changes within the monitoring
window more often than the configured number of signal changes, this is recognized as a
chatter error. If no chatter error is detected within the monitoring window, the window is
restarted at the next signal change.
Chatter monitoring: Number of signal changes
Chatter monitoring: Setting of the signal change
Settings for the tolerated number of signal changes during chatter monitoring within the
monitoring window.
Number of signal changes = 0 deactivates the chatter monitoring function.
Hardware interrupts
Specifies whether the rising or falling edge or both edges trigger a hardware interrupt.

DI 8xNAMUR HF digital input module (6ES7131-6TF00-0CA0)
Manual, 02/2014, A5E03894478-01 15
Sensor type
Specifies which sensor type is connected (see Table 3-1 Pin assignment for
DI 8×NAMUR HF (Page 9)).
For the following sensor types
●NAMUR changeover contact
●Changeover contact, unconnected
●Changeover contact with 10 kΩ
the following applies: The normally open contact channel must be set according to the
sensor type. The normally closed contact channel must be deactivated.
If "Channel deactivated" is shown, this means that the channel is not activated.
Pulse stretching
Sets whether and for how long pulse stretching is to take place.
Pulse stretching is a function for changing a digital input signal. A pulse at a digital input is
extended to at least the configured length. If the input pulse is already longer than the
configured length, then the pulse will not be changed.
Inverted
Specifies whether or not the input signal is to be inverted.
Inversion is only possible with the following sensor types:
●NAMUR sensor
●Single contact, unconnected
●Single contact with 10 kΩ
Potential group
Specifies that a BaseUnit with an incoming supply voltage is located in this slot (see
ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293) system manual).

Pulse stretching
Description
Pulse stretching is a function for changing a digital input signal. A pulse at a digital input is
extended to at least the configured length. If the input pulse is already longer than the
configured length, then the pulse will not be changed.
The pulse-stretched signal is the input signal for the hardware interrupt.
Principle of pulse stretching
The following figure uses examples to show if and how input pulses are changed.

Manual, 02/2014, A5E03894478-01 17
Note
If you set pulse stretching for an input channel, this will also affect the chatter monitoring that
is enabled for this channel. The "pulse
-stretched" signal is the input signal for the chatter
monitoring. You should therefore match the parameter settings
for pulse stretching and
chatter monitoring to one another. By selecting the appropriate values for the parameters
you can adjust the functions optimally to your process.
Note
Pulse stretching in progress is reset in the event of an error in the value
status (QI = 0, e.g.
wire break).

Configuration options of the DI 8×NAMUR HF
Configuration with value status:
●DI 8×NAMUR HF QI
Evaluating the value status
As a result of configuration with value status (QI), an additional byte is allocated in the input
address space. Each bit in this byte is assigned to a channel and returns information about
the validity of the digital value.
Deactivated channels or channels that are not operating correctly return a value status
of QI = 0.
With changeover contacts, the value status of a normally closed contact channel is always
QI = 0. The validity of the signal must be checked on the normally open contact channel.
Address space of the digital input module DI 8×NAMUR HF
The following figure shows the assignment of address space for the DI 8×NAMUR HF with
value status (Quality Information (QI)).
Figure 4-2 Address space of the DI 8×NAMUR HF digital input module with value status
Technology functions
All technology functions, such as
●Pulse stretching
●Chatter monitoring
●Changeover error
●Hardware interrupt
require a valid input signal that returns QI = 1 (no diagnostics detected). Otherwise, they will
not run.
