Via UniApps, you can control the sensitivity of UniStream's response to a Network Storm. In response to a storm, the controller will display an alert and close the PLC ports for a few seconds.
This feature includes system tags for Storm in the struct System->Execution:
Storm Count 1: Storm counter, number of times a storm caused the port to close for 1 second. UINT32
Storm Count 30: Storm counter, number of times a storm caused the port to close for 30 seconds. UINT32
These tags will be updated every 2.5seconds, regardless of whether or not a storm has recurred.
When there is a storm it will be written to the System Error struct:
The error code is 16. (Hex: 00000010)
Date and time of the storm.
Error string: Storm detected; counter is <x> when x is the internal storm counter 1 to 4.
