Operator Panel OP3
Edition 11/99
Screens
On the OP3, the process – for example, a bottling plant or a mixing unit – is
displayed on screens and controlled. These screens are configured by the
configurer for specific users.
On screens, logically associated process values are acquired and provide an
overview of a process or system. In addition to this alphanumeric ”imaging”
of the process, screens provide a means of entering new process values and,
consequently, of controlling the process. Up to 40 screens can be configured
on the OP3.
Process values on a screen can be randomly assigned to subject-related
groups.
Example:
Furnace1 temp. 80C
Furnace2 temp. 78C
Furnace1 cont. 1200l
Furnace2 cont. 3000l
Valve1 press. normal
Valve2 press. high
A screen on the OP3 consists of the following components:
•
a title (optional),
•
screen entries.
Screens can be grouped during configuration in a screen directory, which is
used to display them on the screen and also to edit them. A screen can be
retrieved from its screen directory by its screen number and its screen title, if
configured.
