Update - property of object PmOpcClientData

Enable/disable the automatic data update.
Update As Boolean
oClientData.Update = true
Property access for read and write. The preset value of this property is defined in the "Update from server at server change" configurator of this object.

Tha data group of the OPC client (PmOpcClientData object) that has this property set to true, requires the ongoing update of all its data from the OPC server. The server sends the value to such client automatically at a change of the value on the server.

Because the update of the requested data could pass uncertainly very fast, the parameters for the update can be specified - see property UpdateRate and Deadband.
