uses the following bitmask
OPC_UA_SERVER_STAT_READY_TO_START_BITMASK
OPC_UA_SERVER_STAT_RUNNING_BITMASK
OPC_UA_SERVER_STAT_RESTARTS_PENDING_BITMASK
OPC_UA_SERVER_STARTING_BITMASK
Parameters for the SERVER_STATUS function service request are:
Parameter

16#0003
0000 0000 0000 0000
If the SVC_REQ does not pass power, the operation did not complete.
The SERVER_STATUS word bit definitions are displayed below.
Note that the CPE400's OPC UA server takes up to two minutes to start if the server's configuration files and
certificates need to be generated. This occurs the first time the server is started on a new CPE400 or after the
server is cleared.
While the OPC UA server is starting, the OPC UA SERVER_STATUS service request returns 0010h OPC UA Server
Starting.
