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.

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. | The top talker tables are sortable by IP, byte or frame count.

When clicking on a MAC or IP address of a PROFINET device in the address table, a very detailed summary page for that particular device is shown.The resulting page will be further explained below. | |||
== Statistics per PROFINET device == | |||
=== Overview === | |||
When on the main/global PROFINET statistics pages, you can click on MAC's and IP's listed on these pages. This will bring you to the statistics page of the individual PROFINET device. The overview page (1st tab) provides you with extensive detailes fot that device in a specific/selected time interval. | |||

=== '''Communication relations''' === | |||
This tab shows all communication relations of the device. All communication relations are listed where the device took part either as sender or receiver. | This tab shows all communication relations of the device.
