Time
An OPC UA server needs a mechanism for knowing the current UTC time and facilities to convert to and from local time. The Anybus CompactCom will fetch the time from the network by cyclically sending a request to a OPC UA Discovery Server. The server will be polled every 60 seconds with a timeout of 5 seconds. To configure the address of the Discovery Server, set Network Configuration Object (04h), instance #41, attribute #5 with the URL of the Discovery Server.
Important
If the application is to pass the conformance test for OPC UA, a Discovery Server must be configured in the Network Configuration Object (04h), instance #41.
