Hello, Thanks eschewellinger for your response. Of course, I tried this client example but it don't use Data Sourse to define an OPC UA communication. Actually, I use the wizard "Data Source" from user interface Codesys Dev System SP18 to manage an Opc Client communication. (It is the easier way to avoid the use of the complex OPC ua client library objects). Despite, I need to access dynamically to items exchanged. I tried to use methods from global instance "g Datasource" object without success....

Hi, I am looking for retrieving list of items and their states from a Data Source like OPC UA client inside a program. I tried to use "g Datasource" object but I can't find a practical method to do this. Please does somebody has information about this topic (code example, documentation, ..) ? Thank You

Hi campbell Thank you for the reply. I found a solution using applications included on a same application to share global variables between.

Hi, When I try to create a DeviceApplication in V3.5 SP17 only basic application is allowed. The topic "Using Device Application" is missing in V3.5.17 in online help. Does DeviceApplication no longer maintained for new versions of V3.5 ? I think DeviceApplication is very Helpful to share data between applications like in SP16. Please, someone has news ? Thank You
