"Process Portal A 2.1/0 - OPC Adapter, the Connector may crash or spin" resolves the following:
- Process Portal A 2.1/0 - OPC Adapter, the Connector may crash or spin
Product Concerned
Process Portal A2.1/0
Function concerned
OPC Adapter
A race condition sometimes occurs in read and write operations that may, in worst case, crash the Connector or make it spin. In case it spins the AdvDsOPCServerAdapter process (AdvDsO~2) will take the rest of the CPU load, which causes a total load of 100%. This requires manual restart of this process. Fail-over to a parallel connectivity server will not be carried out.
If a read/write is made with multiple items, which have different default update rates (configured in the Control Connection Aspect (CCA)), the OPC Adapter will not complete the transaction, i.e. no response to the client is sent. In case the read/write operation is synchronous, the client will hang.
