You are on the right track with GetPropertyValue.
The property you are looking for is AccessRights. The values are (from constants in DAAccessRights):
  • 0: NoAccess
  • 1: Readable
  • 2: Writable
  • 3: Both

Hi.

I can't find a method to get information about the 'direction' for an item.
Maybe there is no direction info to get.

I tried EasyDAClient.GetPropertyValue(,,,DAPropertyId.WriteBehavior), but I get an exception.

I'm not an OPC expert, so any help is very much appreciated.
