Escalation levels

The OPC Router recognises when too much status data is being recorded or the database memory is almost full. To prevent a full memory and RAM, the OPC Router automatically initiates increasingly stronger countermeasures. The transmission of user data is NOT adjusted by these measures! The measures only affect the status recordings of the OPC router. The recording of user data is to be ensured by the measures. In the basic settings of the OPC router, you set the extent to which the OPC router may fill the status databases.

There are the following escalation levels:

• Escalation level 0:
  • Normal behaviour
• Escalation level 1:
  • Ring buffer batch size exceeded
  • Status database 60% full
  • Action: No more logging of transfer values from successful transfers for fast-triggering connections
• Escalation level 2:
  • Ring buffer batch size exceeded by a factor of three
  • Status database 80% full
  • Action: No more logging of transfer values from successful transfers
• Escalation level 3:
  • Ring buffer batch size exceeded by a factor of six
  • Status database 90% full
  • Action: Log no more transfer values
• Escalation level 4:
  • Ring buffer batch size exceeded by a factor of ten
  • Status database 100% full
  • Action: Deactivate status recording of transfers completely

The current escalation level can best be seen in the status storage options.
