Planning for Process Industries (PP-PI)
An output of process instructions of a control
recipe for display and processing at the screen.
The PI sheet enables a dialog between PP-PI and
the line operator in a line which is operated manually (either totally or
partially). Depending on the process instructions, the PI sheet supports the
following functions:
- display of control information in natural
language
- recording of actual process data
- reporting the entered or calculated data using
process messages
- recording inspection results by jumping
directly to the QM module
- calling user-defined function modules in order
to start a dialog or retrieve data from internal or external
applications
