Method Description
CMD device The relevant parametrisa-
parametrisation tion is selected and carried
out directly via the CMD
software.
It is possible to save the in-
dividual parametrisation
within the CMD software.
CMD user func- Macros with the desired
tions automat- parametrisation are cre-
ically after ated via the user functions.
power on These macros are transmit-
("boot" active) ted by the interface mod-
ule after power on.
CMD user func- Values (parameters) can be
tions accessed transferred to the user
by user pro- functions via Interbus pro-
gram cess data words. In this
way, parametrisation can
be undertaken flexibly via a
PLC user program.

Advantages
– Fast, simple paramet-
risation during com-
missioning for testing
the parameters
– CMD-uniform para-
metrisation
– Data are loaded auto-
matically after power
on and are therefore
retained if the CPX
terminal is replaced.
– CMD-uniform para-
metrisation
– Parametrisation data
are saved in the user
program. Remote
maintenance is there-
fore possible
Disadvantages
– Parametrisation is
saved locally in the
CPX terminal and is
lost after power off or
if the terminal is re-
placed.
– Access via remote
maintenance is not
possible.
– Parametrisation is
saved only in the in-
terface module
memory and not in
the complete control
project.
– Access via remote
maintenance is not
possible
– Sequential paramet-
risation by means of a
large number of user
functions
