=== Introduction === | |||
PROFINET is an open Industrial Ethernet communication protocol, based on international standards. It is designed to exchange data between controllers and devices, mostly in manufacturing and/or automation environments. Since its introduction in the early 2000s, it has grown to become the most well-adopted Industrial Ethernet solution. | PROFINET is an open Industrial Ethernet communication protocol, based on international standards.

Allegro Packet’s incident engine allows for automatic reporting of PROFINET alarms and threshold based triggers to e-mail and syslog. Also PROFINET traffic recording and automated event-based PROFINET packet capturing is readily available to you in Allegro Network Multimeter. | Allegro Packet’s incident engine allows for automatic reporting of PROFINET alarms and threshold based triggers to e-mail and syslog.

=== '''Overview''' === | |||
The overview page (1<sup>st</sup> tab) is the global information dashboard revolving PROFINET traffic. | |||
[[File:Profinet Overview.png|border|900x900px]] | |||
These include graphs and tables depict: | |||
* PROFINET traffic VS total traffic | |||
* Global PROFINET PN-RT errors | |||
* Millisecond micro burst analysis | |||
* Global PROFINET jitter | |||
* The top 5 senders and receivers | |||
Whenever graphs depict anomalies such as high loads, RT-errors and/or high jitter...these instances can be zoomed into by selecting (click 'n drag) a spike in the graph with the mouse. | |||
The top talker tables are sortable by IP, byte or frame count. The download button at the end of each device line, provides you with a pre-filtered pcap, containing only the conversations from that specific IP/MAC during the selected time interval. Both forward capturing in real-time as well as retroactive packet extraction from an active ring buffer are possible. | |||
=== Global stats === | |||
The global stats page (2<sup>nd</sup> tab) provides you with detailed statistics and a summary for a specific/selected time interval. | |||
[[File:Profinet Global stats.png|900x900px]] | |||
The (time interval) information listed on this page includes: | |||
* Total PROFINET bytes and frames count | |||
* Total PROFINET alarms and errors count | |||
* Average and maximum PROFINET jitter | |||
* PROFINET unanswered request count | |||
* PROFINET unrequested response count | |||
* PROFINET response time information | |||
Again, whenever graphs depict anomalies such as high loads, RT-errors, alarms and/or high jitter...these instances can be zoomed into by selecting (click 'n drag) a spike in the graph with the mouse. This not only helps narrow down the timeframe to troubleshoot, it also results in the most optimized pre-filtered pcap files, if those are needed. | |||
