Message level
The message level is the highest level on the OP. At message level, wai-
ting event messages, alarm messages and system messages are displayed.
After the OP starts up, it changes to message level if
– a system message or an alarm message is waiting to be displayed
– a start screen has not been defined in the configuration. In this case,
the OP displays the standby message (refer to section 7.1.1).
– Screen level
At the screen level, functions are chosen, serviced and executed. If a
start screen has been defined in the configuration, the OP changes to
screen level after it starts up and calls the start screen. From the start
screen you branch, depending on the configuration, to other screens.
On the screens, you view current process values, can enter values and
initiate functions by means of soft keys.
