16.2.2 Forcing the OPC Server to Close Down
The OPC server for SIMATIC NET is started automatically by the operating system
when a client wants to use it. The OPC server maintains reference counters to be
able to recognize when the last registered client is closed. The OPC Server then
closes itself down. This is only possible when the clients set and reset the user
counters of the OPC Server correctly.
If a client closes down irregularly and the user counter is not reset, the OPC server
will not close down although no more clients are active. The server continues to
keep the communication connections open.
In this case, it is a good idea to stop the OPC server manually.
