1.3 CPX parametrisation
1.3.1 Fail−safe or idle mode parametrising example
Depending on your application and the CPX node used,
check if corresponding fail−safe or idle mode parametrising is
necessary.
Fail−safe parametrising or idle mode parametrising allows
defined I/O states to be established in the event of a fault
or if the bus fails.
Additional information can be found in the respective
Appendix C.3, C.2 or C.1.
1.3.2 Start−up behaviour of the CPX terminal
The desired parametrisation of the CPX terminal should be
carried out in the start−up phase or after fieldbus interrupĆ
tions by the bus controller or the scanner/bus master, providĆ
ing this is supported by the fieldbus protocol used.
Note
When exchanging a CMAX, parametrisation is not
automatically established via the CPX node.
In this case, it is imperative that the CMAX be correctly
parametrised, as during the initial start−up. See
section 1.1.2.
Follow the instructions for exchanging components in the
CMAX system description.
