Operator Panel OP3
Edition 11/99
Using the OP3 with Its Standard Functions
The configuration software ProTool, includes a configuration which contains
standard screens. You can choose all the functions required for operating the
OP3 by using these standard screens. The different functions are described in
this manual with reference to the standard screens.
The English-language standard screens, which are loaded from the firmware
of the OP3, remain active, once you have switched on the operating voltage,
until a configuration is loaded (refer to section 4.2).
4.1 Operating Levels
In OP3 operation, you have to distinguish between two distinct operating
levels, between which you can switch:
•
Message level
At the message level, current messages are displayed.
•
Screen level
At the screen level, functions are chosen, serviced and executed.
The message level is the highest level on the OP3. At message level, waiting
event messages and system messages are displayed. After the OP3 starts up,
it changes to message level and displays the standby message.
The screen level is reached by pressing the
ENTER
key. The first screen to
be called is the start screen. From the start screen you branch, depending on
the configuration, to other screens. On the screens, you view the actual
process values, and you can enter values and initiate functions by means of
soft keys.
The linking of individual screens is referred to as a screen hierarchy. As you
go further down the screen hierarchy, you go stage by stage right back to the
start screen by pressing the
ESCAPE
key. From here you can return to the
message level by pressing the ESCAPE key. You can also return directly to
the message level from a screen, depending on the configuration.
