6.5.4 Parameter DB
Task
If you want to modify the machine data and incremental dimension tables during
operation, you require a parameter DB (see Appendix C.2, page C-9) in which
these data are stored. The parameters can be modified by the user program or by
an operator control and monitoring system.
You can export the data displayed in the configuration software to a parameter DB.
You can also import a parameter DB into the configuration software and display it
there.
There can be several sets of parameter data for each channel (for example for
different recipes) the required set being selected in the program.
