The purpose of the GetStatus service is:
- It provides a common mechanism for checking the status of the server - whether it is operational or in need of maintenance.
- It provides a common mechanism for obtaining vendor-specific information about the server that is not available through the other OPC services (version number, etc).
- Provides insight for clients as to the relative time synchronization between the client and server. As an example, this information is useful for Read requests.
