Hi i am staring to work whit scada, and i got asked which type of communications its better?

I understand the Synchronous communication, its read the values of point directly from OPC server,
While the Asynchronous communication, implement a cache that have a processes running in a thread whit a callback handler that load the values in the cache.

But i need to know in which cases those are better, and what its the best practices to use them.

Thx for the help
