1 General information
Please read this document thoroughly from start to finish before you begin installing the device and putting
it into operation.
1.1 Purpose of use
The PROFINET-INspektor®NT permanently monitors all data traffic in a PROFINET (PN) master system.
You will receive a maintenance requirement notification when critical changes that could lead to unplanned
system downtimes are detected.
Based on the report analysis (purely passive behaviour), the following quality parameters are monitored:
•Update rate
•Error telegrams (sent/received)
•Alarms (low and high-priority)
•Telegram gaps
•Telegram overtakes
•Bus node failure
•Bus node restart
•Jitter
•Netload (sent/received)
One PN-INspektor®NT is required per PROFINET master system. This PN-INspektor is looped into the
connection between the IO controller (PLC) and the first device (switch) for analysis, or integrated within
the network through a feedback-free measurement point (e.g. PNMA II; art. no. 114090100).
No additional IP addresses or adjustments to the PLC program are required for using the PN-INspektor®
NT. It works in an entirely manufacturer-independent way; i.e. the analysis works completely independently
of the type of control system and IO devices.
For long-term analysis, the PN-INspektor®NT can remain in the bus system without any time restrictions.
The relevant telegram traffic is continuously analysed and evaluated in order to detect deviations from
normal conditions and trigger alarms.
1.2 Use of Open Source Licenses
Indu-Sol offers to provide source code of software licensed under the GPL or LGPL or other open source
licenses requiring source code distribution. The individual licenses used in Indu-Sol products can be
found in the product front ends.

The following icons were used in the Web interface for a simple overview of the individual statuses of the
network and devices:
No faults: PROFINET communication is working without any problems.
Warning: A communication fault or a diagnostic message has appeared
in the network, or originated from a device, and this fault or message has
not yet led to system failure. The sources of these events should be
localised and resolved.
Fault: A critical fault has appeared in the network, or originated from a
device, and this fault leads to system failure. It is urgently necessary to
resolve the fault.
The bus communication in the network has failed or cannot be detected
by the PN-INspektor®NT (serious fault in the network) or the device is no
longer communicating or is not in the network.

3.1 Homepage
The homepage provides a complete overview of the status of the connected PROFINET system since the
start since the start of the current measurement.
If there are no entries here, the system is working stably and there are no urgent actions required.
Figure 7: Complete overview
There are additional helpful functions for obtaining more detailed information on the state of the network.
These can be accessed via drop-down menus or the Alarm Overview.
Specifying the time period, with a corresponding display of device information, is possible in the sub-menus
of the homepage. The relevant period of evaluation can be selected by switching the time window between
“current”, “last minute” and “history”. The “current” setting always displays the node condition (live list) at
that particular moment, and the “last minute” option shows the device information over the course of the
previous minute. With the “history” pre-selection, all data is displayed since the beginning of the recording
or the last time the “Delete data” or “New measurement” function was commanded. You can use these
different time references to determine whether PROFINET faults are occurring occasionally or permanently.
To adapt the user language of the web interface, it is possible to select the language by means of a mouse
over function on the "Language" item.
Language switching only affects the user interface. The settings for the display and the log text are
made by changing the system language (see section 3.5.1.4 Time and language settings).

In addition, changes made to the basic settings in the "Device status" menu (see section 3.5.2.2. Device status)
are indicated by the message "Status Settings have been changed" and in the "Triggers & Alarms" menu (see
section 3.5.2.3 Triggers & Alerts) by the display "Alarm Settings have been changed".
Alarm overview
In the alarm overview the number of unacknowledged alarms are indicated to you. The entries in the alarm
list are opened automatically with a mouse click on the alarm bell.
You can also perform the following functions in this window:
Acknowledge alarms: Unacknowledged alarms are acknowledged, but the entries stay in the alarm list.
The switch contact for the alarm is reset.
Delete alarms: All entries in the alarm list, including snapshots, are deleted.
Delete data: All previously recorded data is reset and the network analysis is restarted. The
device information (IP address, PN name) and configured settings are retained.
New measurement: This item is to be applied in the event of alternating use in different PROFINET
systems. By selecting this function, all previous entries including the node list are
deleted, and the network analysis is restarted. Any configuration settings made
are retained.
Hints

Web interface and selection functions

Hint:
By regenerating the participant list, it is necessary to select the automatic deactivation
of new participants again, if desired. Settings for the configuration of monitored
connections can also be reset by pressing an optional selection field with the start of a
new measurement. Otherwise, the previously selected connections will continue to be
monitored.
Timeline
The timeline offers you a compact visual overview of the state of the network over the course of time. If
different network statuses are analysed within the course of the monitoring period, the point in time when
the respective status change started is presented as a new node (maximum 50 entries). Detailed
information accumulated within this time frame can be accessed by selecting one such node. The minimum
time period for a status change (new nodes) is one minute.
Figure 9: Timeline entry
The individual status changes can be adjusted for each node separately (See point 3.5.2.2
Device status) in order to adapt the display to the plant conditions.
