Using the OP with Its Standard Functions
Once the operating voltage has been connected, you have to load a configura-
tion into the OP so that you can operate it. The OP is in Transfer mode until a
configuration is loaded.
The configuration software supplied to you, ProTool/Lite, includes a configu-
ration which contains standard screens. You can choose all the functions re-
quired for operating the OPs by using these standard screens. The different
functions are described in this manual with reference to the standard screens.
3.1 Operating Levels
In OP operation, you have to distinguish between two distinct operating le-
vels, 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 OP. At message level, waiting
event messages, alarm messages and system messages are displayed. After
the OP starts up, it changes to message level and displays the ”standby mes-
sage”.
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 current pro-
cess values, can enter values and initiate functions by means of soft keys.
The linking of individual screens is referred to as a ”screen hierarchy”. If you
go to the bottom of the screen hierarchy, you go back one stage by pressing
key ESC, right back to the start screen should you wish. From here you can
return to the message level by pressing the ESC key. You can also return di-
rectly to the message level from a screen, depending on the configuration.
