3.2.1 Parameterisation during switch-on [system start]

Festo CPX-FB36-EN en 1611a English
Parameterisation during system start of the CPX terminal is
initially dependent on the setting of the parameter [system
start]. This parameter establishes whether the default para­
meters or the parameters saved by the user in the bus node
are used when switching on the CPX terminal.
The parameterisation is loaded again after every interruption
of the power supply or the network connection. An exchange
of individual CPX modules is therefore possible, for example,
without the need for re-parameterisation.
Sequence of parameterisation when the CPX termin­
al is switched on
System start with standard parameters
("default parameters")
1. The controller transmits the parameterisation that is
saved in the controller to the bus node.
2. The bus node distributes this parameterisation to the
individual modules.
System start with saved parameters
1. The bus node distributes the parameterisation that is
saved in the bus node to the individual modules.
The parameterisation saved in the bus node can be overwrit­
ten accidentally by the controller.
Prevent accidental overwriting of the saved parameterisa­
•
tion by changing the "Configuration" connection paramet­
er using the "Studio 5000" software.
