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.
The desired parametrisation of the CPX terminal should be
carried out in the start−up phase or after fieldbus interrup
tions by the bus controller or the scanner/bus master, provid
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.
