Set Client Properties

You can modify many properties specific to the created client. These include Timeout, UserData, Host (before connection), and ServerID (before connection). Modify these properties as you would any other field of a MATLAB® structure.

Set the Timeout Property

As OPC transactions often occur across networks, you might encounter cases where calls to those servers take some time to return. To change the function timeout of the OPC HDA client object, assign a new value to its Timeout property:

hdaClient.Timeout = 12
hdaClient = 
OPC HDA Client localhost/Matrikon.OPC.Simulation.1:
               Host: localhost
           ServerID: Matrikon.OPC.Simulation.1
           Timeout: 12 seconds

             Status: connected
