Hello,
i want to use OPC communication and Matlab to read and write data from/to a Logix5561. A Topic is already configured on RSLinx. On my PC i installed MATLAB and i can connect to the OPC Server using Simulink opc Toolbox. My Problem occurs when i want to add Items, i receive a Simulink error saying Name space Browsing not avaible. and Matlab says could not retrieve name space for Server. Error was: StartItemId is not a branch in the Server Namespace.
how can i solve this Problem ?
Thanks

OPC DA has items and branches. Items are used for i/o. Branches are for browsing.
Sounds like you are trying to browse an item.

It seems like when Browsing on Simulink it didn’t wotk, i tried to add an item directly without Browsing and it works.

I have the same problem,so when you add an item directly,can simulink write data to opc server correctly?And when you open another opc client,can this client read the data you wrote?Thank you!
