Connecting Simulink to PI (Write and Read)

Hello,

 

I am trying to send data from a simulated plant in Simulink to a PI server (through OPC write) and then bring the data back to Simulink (through OPCRead). However, I am getting the following errors:

 

Error evaluating registered method 'Start' of MATLAB S-Function 'opcslread' in 'Sinewave2/OPC Read'. The following is the MATLAB call stack (file names and line numbers) that produced this error:

 

Could not create all items for read block 'Sinewave2/OPC Read'.
The specified operation timed out.
Unable to undo the fully or partially completed operation on the OPC Server.

 

I get the following error on running the command "additem(grp,items);" in the file OPCDARead.m that is provided by the OSIsoft.:

 

The specified operation timed out.
 Unable to undo the fully or partially completed operation on the OPC Server.

 

I appreciate any feedback.

 

Thanks
