Status and history

Statistics of all incidents

Topology with status

With PROFIBUS-INspektor^® NT you are well equipped to "reach retirement" with your PROFIBUS systems without any disturbances. The compact version combines all necessary functions for diagnosis, alarming and reading PROFIBUS data in a single device. This range of functions means that the PROFIBUS Inspektor^® NT can also be used for mobile applications as well as for acceptance and service purposes.

The diagnosis device PROFIBUS-INspektor^® NT records your PROFIBUS network with all active devices and visualizes them clearly using an embedded web interface. As a passive data collector, it monitors the logical data traffic and alerts you at the first signs of malfunction - not just when your PROFIBUS system has already failed. The PROFIBUS-INspektor^® NT allows a complete online analysis of all quality-relevant events such as:

• Error telegrams
• Telegram repetitions
• Device failures
• Device diagnostic data
• Restarts
• BUS cycle times

PROFIBUS-INspektor® NT: Features and advantages in detail

Interruption-free reading of all data

No additional software is required for reading the data from the PROFIBUS-INspektor^® NT. You only need an Internet browser (e.g. Mozilla Firefox) to access the web interface integrated in the device. This allows you to view both the current network status and a history of past events.

Note: The web interface of PROFIBUS-INspektor® NT can be accessed conveniently via the web browser of the connected device (e.g. notebook or tablet) - without any additional software required. No active Internet connection is required.

Topology function with status information

For the evaluation of a PROFIBUS network, knowledge of the real wiring of the individual devices among themselves is a central prerequisite. This topology can be stored on the PROFIBUS-INspektor^® NT with all important infrastructure components, such as repeaters and measuring points, including the device information, and can be retrieved as required. In addition, current and past states of individual nodes are displayed in color. This makes it much easier to limit existing errors to certain segments or conspicuous nodes.

Error statistics with detailed timeline

You can see clearly which device is most frequently affected by the events that have occurred (e.g. telegram repetitions). This provides you important information for troubleshooting.

Automatic alerts for PROFIBUS errors

As soon as a threshold is exceeded, the PROFIBUS-INspektor^® NT creates an alarm to warn the operator in time to perform targeted, planned maintenance. Warnings can be given in several ways. An LED on the PROFIBUS-INspektor^® NT shows directly whether errors occurred in the network. In addition to this warning, a potential-free contact can be switched, e.g. to send a message directly to the control system. The third option is to send an e-mail to notify the responsible maintenance team as soon as possible.

By accessing the web interface of PROFIBUS-INspektor® NT, a detailed alarm list shows which error occurred on which device at which time. In addition, it records which event (threshold value) triggered the alarm. The internal memory allows to record up to 2000 alarm messages, each alarm is assigned to a snapshot with up to 1000 PROFIBUS telegrams.

Alert options

Easy creation of a PROFIBUS acceptance log

The PROFIBUS-INspektor® NT offers you the possibility to create a complete acceptance log of your PROFIBUS project with just a few clicks and in a short time. It contains all important information on the respective PROFIBUS system, from topology to bus-related EMC conditions.
