ASync Write calls
Description
This counter indicates the number of requests the OPC DA client made to edit data asynchronously.
The client does not wait for the server to provide an immediate response. Instead, the client continues with its tasks while the server asynchronously notifies the client once obtaining the requested data. This method allows the client to perform other operations without being blocked by the write request.
TIP:
- This value should match the one in ASync Write Complete calls. Any discrepancies may suggest a potential loss of transaction.
- There might be a slight time delay between the request for ASync Write and the update of the ASync Write Complete Calls counter.
