OPC DA case sensitive

[m.sabitov]

Hi!
OPC DA server in WINCCOA have case sensitive mode. Can I use case insensitive mode?

Can you please describe in detail what you want to do.
When browsing the server you get the items in correct notation and therefore reading them case insensitive is normally not needed.

For example: Valve1.Open - this tag in wincc opcda server. Some opc clients trying to get tag Valve1.open, and get error.
In my case reconfigured all clients unreal.

I'm not sure if this will work in WinCC OA because you can define a DP-type with the following structure
Valve1
Open
open

If now all items are in lower case you cannot differ between these items.
In your case you have written that the OPC client expects Valve1.open.
Why is the first part case sensitive and with "V" in capital letter?
