KP07 VDU (VISUAL DISPLAY UNIT) CONSOLE
IV. GENERAL PRESENTATION
The KP07 console is a man-machine interface with a black and white liquid crystal graphics screen, back-lit,
with definition 240 x 128 pixels. It also has 2 indicator lights and 12 keys.
The principal functions of the console are :
•
Management of the tree structure of interactive screens.
•
Permanent updating of all dynamic parameters displayed on the different screens.
•
Saving successive states of predefined variables to be used for analogue and event logs.
A KP07 console can be connected to a maximum of 8 distinct controllers, on condition that they all have the
same structure of variables. The number of controllers connected is declared in the application program for the
VDU. If a single CPU is connected, its card number is also declared.
The controller / VDU link is serial type and uses JBUS protocol. On connection, the console tries to establish a
dialogue with the declared controllers. If, after 3 attempts, the console cannot communicate with a controller,
the latter is set to "disconnected" status. The link problem is then displayed on the screen (if the disconnected
controller is selected for operator dialogue) and saved in the event log. The KP07 then makes regular attempts
to reconnect.
Communication speed is 4800 baud. Data is transferred in 8-bit format (1 start, 8 bits, odd parity, 1 stop).
