5. REMOTE FUNCTIONS
5.1 Remote function handling
On the CCU all incoming remote functions are handled by the Remote Function Services
(RFS). During start-up of the system applications register their remote controllable functions
at the Remote Function Services.
When a remote function request is received by the CCU, that request is passed to the RFS
sublink. If the function is available, the data structure will be prepared for the response data.
During this process general failures may occur. The RFS sublink handles these failures by
returning an empty response (only containing the function identifier and the error-code, no
extra data). The error-code informs the remote controller which general failure has occurred.
Possible error codes are:
RFSE_BADFUNCTIONID The remote function is not available
RFSE_ALLOCFAILED Response space allocation failure
RFSE_NOACCESSPERMISSION The remote function is not authorized
These error-codes are described in Appendix C.
5.2 Simultaneous operation from Control PC and Remote Controller
In some cases it is possible to have the same application running on the DCN Next
Generation Control PC and (simultaneously) having that application running on a remote
controller. Some applications can only be active on one place at a time. In the table below all
possible combinations are depicted. All legal combinations are marked +. All illegal
combinations are marked -. If an illegal combination is created, the proper working of DCN is
not guaranteed anymore.
