2.8.1 Start parameterisation during switch-on (system start)
Parameterisation during system start of the CPX terminal is
initially dependent on the setting of the system start paramet-
er. Th i s parameter specifies whether Start parameterisati o n
will be loaded from the PROFINET-I/O Controller or from the
bus node.
Note
The Start parameter set is loaded again (according to the
rules descri bed above) after every interruption of the net-
work connection or of the power supply.
An exchange of individual CPX modules is therefore possible,
without the need for new manual parameterisation.
Sequence of Start p arameterisation when the CPX
terminal is switched on
Sequence with system start parameter “Default Paramet-
ers”:
– The PROFINET-I/O controller loads the Start parameter
set into the bus node.
– The bus node then distributes the parameter set to the
modules.
It does not matter whether there is a memo ry card in the
bus node or not.
Sequence with system start parameter “Saved Paramet-
ers”:
– The bus node distributes the saved (in the bus node)
Start parameter set to the modules.
