Best method to read a lot of opc variables - by: mpp

Hi, at the startup of my machine interface I need to read (and if a compilation variable is set write) more then 900 OPC variables which are machine parameters to control all the motors, parts, etc.

Actually I'm preparing a list of ItemDescriptors and read them in block with ReadMultipleItemsValue:



Is it correct?
If I scan the valueResults a lot of variables has the timeout exception.

What should I do?


Thanks in advance
