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. Therefor, 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.

Quality parameters (traffic light principle) are visualized in the topology
topology scan of the primary IIT network
Support of MQTT alarm actions
Telegram streaming directly via INspektor
Optional login page & configurable email encryption
New alarm triggers: interval triggers, SNMP trap receivers, topology changes
 
Continuous Network Monitoring
 
 
A permanent analysis of the network status is essential to ensure the PROFINET communication clocked in real time or to overview the amount of extrinsic communication (e.g. Ethernet by camera systems and displays). The PROFINET INspektor® NT is permanently integrated into the plant network and permanently monitors the logical telegram traffic during running production conditions. The plant operator knows the current status of the network at any time and is therefore able to initiate concrete countermeasures before the fieldbus fails and the plant comes to a standstill. An integration of the PROFINET INspektor® into the detection system is possible and useful for permanent monitoring.
