There are several ways this can be done. Here is how it works:
1. Upon startup, EasyDAClient component establishes the initial values of the timeouts, by looking into a shared placed in the registry. If they are not found at all, it uses internal default values (1 minute, mostly).
2. If any value *is* found in the registry, it is used as the initial value of the timeout. The registry values are configured using the EasyOPCOptions utility, which is installed with the product (accessible from the Start menu). There is a document (help file) for the utility as well within the product, plus online here: www.opclabs.com/files/documents/QuickOpc/Latest/EasyOPCOptions.pdf .
Here is how the utility looks like:
3. Once the initial values are established, they are stored in the Timeouts object, which is a property on the EasyDAClient:
You can manipulate the timeouts directly from your code in this way.
Note: In .NET, there are static properties instead of the registry-based defaults.
