Description

The OPC client can request data either synchronously or asynchronously. When it subscribes synchronously it waits for the subscribed data to be delivered until it continues the execution. The time it takes to read the data can be measured. When the OPC client subscribes asynchronously it issues a request and is then interrupted (callback) each time data arrives. If you combine asynchronous reading with a cyclic subscription interval you will get all the OPC items from the OPC server at the first refresh but afterwards you will only receive data when they are changed. Asynchronous subscription with a cyclic subscription interval towards the cache (typically 1 second) is the recommended subscription for most applications. With such a subscription the data is never older than 1 second and you minimize the data flow between the OPC client and the OPC server to the changed data (once the first set of data is transferred). As most attributes do not change at all during the subscription the load on the PCs where the OPC server and OPC clients reside is minimized.
