Connection Priority

The priority of a connection can be set in the connection settings. This function is particularly designed for large projects that utilize the router's capacity fully or partially. Prioritizing connections ensures that important connections are executed first when the router is under high load.

Priorities

Priority	Description
High priority	High priority connections are executed most reliably when the router is busy. High priority connections are well suited for time-critical tasks such as alarm and event management or the synchronization of time-critical systems such as production lines. Note: If the router is completely busy with high priority connections, no other connections will be executed.
Normal priority (default)	Normal priority connections are well suited for tasks that are not time-critical, such as logging or synchronizing non-time-critical systems such as databases. Note: While the router is fully utilized with high and normal priority connections, no low priority connections are executed.
Low priority	Low priority connections are well suited for tasks that are not time-critical and where longer delays are not a problem, such as archiving data or deleting old data.

note

For high-priority connections, there are reserved threads in addition to the standard 80 threads for the OPC Router.
