Call the machine parameter editor through the MOD function "code
number":
• By entering the code number 95148, you gain access to the complete list
of machine parameters.
• By entering the code number 123, you gain access to a subset of machine
parameters. This subset can be changed by the user (see User's Manual).
Machine parameters that can be accessed through the code number 123
are indicated in the list with the symbol CN123.

To exit the machine parameter editor, press the END key.
You can access some machine parameters without first entering a code
number.

In MP7330.x, define up to 16 machine parameters and define the associated
dialog in MP7340.x. The dialog is shown whenever the USER
PARAMETERS soft key is pressed (see "Display and Operation").

Select the MOD function USER PARAMETER.
To protect the current machine parameter list from being edited through the
code number 95148:

In the OEM.SYS file, define a new code number in the entry
MPPASSWORD = [code number], for editing the machine parameter list.
Then it is no longer possible to edit through the code number 95148.
To protect individual machine parameters against editing:

In the MPLOCKFILE = entry in the OEM.SYS file, enter the path of a
machine-parameter subfile. Then it is only possible to edit those machine
parameters that have no value assigned in this file. If there is a difference
between the current MP value and the MP value in this subfile, the control
displays an error message and a window offering the value from the subfile
for your acceptance.
You can also change the machine parameters through the PLC. The following
modules are available for this purpose
n
Module 9031 Overwrite machine parameter
n
Module 9032 Read machine parameter
n
Module 9310 Read the machine parameter from the run-time memory
n
Module 9033 Select machine parameter file
n
Module 9034 Load machine parameter subfile
The machine parameters that you can change with Module 9031 or
Module 9034 are indicated with PLC in the overview.
