Escalation Levels
The OPC Router recognizes when too much status data is being recorded or when the database memory is almost full. To prevent the memory and RAM from becoming full, the OPC Router automatically initiates increasingly stronger countermeasures. The transmission of user data is NOT affected by these measures! The measures only affect the status records of the OPC Router. The recording of user data should be ensured by the measures. In the basic settings of the OPC Router, you can set how far the OPC Router is allowed to fill the status databases.
There are the following escalation levels:
- Escalation level 0:
- Normal behavior
- Escalation level 1:
- Ring buffer batch size exceeded
- Status database 60% full
- Countermeasure: No longer log transfer values from successful transfers for fast-triggering connections
- Escalation level 2:
- Ring buffer batch size exceeded by three times
- Status database 80% full
- Action: No longer log transfer values from successful transfers
- Escalation level 3:
- Ring buffer batch size exceeded sixfold
- Status database 90% full
- Action: No longer log transfer values
- Escalation level 4:
- Ring buffer batch size exceeded tenfold
- Status database 100% full
- Action: Completely disable status recording of transfers
The current escalation level can best be seen in the status storage options.
