Description

Intelligent measuring point for online analysis

The PROFINET-INspektor® NT is an important diagnostic tool for certification, commissioning and inspection of new installed PROFINET networks. Depending on the pre-defined trigger functions the events are registered in the PROFINET-INspektor® and summed up and stored per device. Hereby, the INspektor® detects quality values like network load, data throughput, refresh rate, telegram gaps and telegram jitter, that mirror the current status of communication quality. These parameters serve as commissioning and inspection criteria for new installations, but also as important information for maintenance and (remote) service.
