enum states
enum with the different possible states - these are common to all PU!!!

Sets the state to the new state given by the name of the state

const char* getcState()
Returns the state to the new state as a string

Documentation

Proxy class for the data logger. This object represents the data logger interface, which is implemented by the ndd_event_server. This server has currently the dual nature of being the recipient of the data from the crate controllers as well as the data logger. The run control communicates with the server through a shared memory segment. The server is forked off by the run control as the ddEventServer. See also that object for details.
The following things happen during the state transitions:
initialise:
connect to the ndd_control shared memory segment and check that the server is up and running
download:
update the field filerule and enable_logging if necessary
start_run, end_run:
Do nothing.

DataLogger(const char *name, const char *design)
