Process-Dependent Operator Guidance
Different action is normally required or allowed in different operating situa-
tions. To support changing requirements during process control, you can con-
figure the following measures, which provide the operator with situation-spe-
cific purposeful help:
screen-dependent soft keys,
global function keys and
user-defined screen hierarchies.
11.1 Branching by Means of Soft Keys and Function Keys
You can assign function calls to the function keys on the OP5 and the OP15.
We distinguish in this instance between local and global assignment. Global
means that the assignment applies to the entire configuration. Local means
that the assignment applies to one screen entry only. This makes it possible
for the operator to initiate functions as and when required by the situation.
When the assignment of function keys may vary from screen entry to screen
entry, the keys are referred to as soft keys.
The following keys can be assigned as soft keys on the different devices:
Keys F2 to F5 of the function keyboard may be configured as soft keys.
Function keys F1 and F6 may be assigned globally during configuration.
Keys F1 to F8 beneath the display may be configured as soft keys. Function
keys K1 to K16 may be assigned globally during configuration.
While configuring soft keys, you must make sure that function calls which
are required to be permanently available, i.e. also during screen editing, are
not assigned to keys which you intended to be soft keys.
