Figure 4.1.3.4-1 overleaf defines online diagnostics
data flow and control logic. OLD receives operational
commands from COPSY in the OLDQ Also, supervisor and
periodic request are entered in the OLDQ.
OLD replies to operational and supervisor requests.

Figure 4.1.3.5-1 overleaf illustrates the WDP data
flow and control logic.
The WDP standard software drivers are shown outside
the box, hereas the four application software processes
are shown within the box.
The following sections handle input to the WDP from:
- a PU
- a VDU
- the CCB scanning driver.

4.1.3.5.1 I̲n̲p̲u̲t̲ ̲t̲o̲ ̲t̲h̲e̲ ̲W̲D̲P̲ ̲f̲r̲o̲m̲ ̲a̲ ̲P̲U̲
The PU-IN driver recognizes three types of PU input:
- VDU data
- LP data
- WDP data
and sends the data to three associated queues:
-VDU queue
- LP queue
- PU queue
VDU data are analyzed in the VDU-HANDLER and LP-HANDLER
process respectively and printed by the corresponding
VDU and LP drivers. The LP-HANDLER synchronizes LP
output.
The WDP data in the PUQ contain keep aliv messages
and direct WDP commands. The keep alive messages are
handled in the PU-HANDLER, whereas WDP commands are
executed in the SYS M&C process. The non-arrival of
a keep alive message is signalled to the SYS M&C process
by the PU-HANDLER.
4..3.5.2 I̲n̲p̲u̲t̲ ̲t̲o̲ ̲t̲h̲e̲ ̲W̲D̲P̲ ̲f̲r̲o̲m̲ ̲a̲ ̲V̲D̲U̲
VDU input is directed to the VDU queue at the VDU-HANDLER
by a VDU-IN driver. Three types of VDU input are handled:
- offline PU commands
- direct WDP commands
- online PU commands.
The VDU-HANDLER sends oline and offline PU data to
a PU-OUT driver. Direct WDP commands are executed in
the SYS M&C process. Offline commands are copied at
the record WDP-LP.
4.1.3.5.3 C̲C̲B̲ ̲S̲c̲a̲n̲n̲i̲n̲g̲
The CCB driver periodically scans the CAMPS crates.
Exceptions are reported to the SYS M&C process, which
determines further actions, e.g. an active PU errr
is handled by disabling the AC PU and by commanding
the SB PU to become active.
Peripheral device exceptions are reported to the active
PU.
