Parameterisation

3.7.1 Introduction to parameterisation
The CPX terminal is supplied with factory-preset parameters (default parameterisation).
The system characteristics of a CPX terminal and of individual modules and channels can be parameter­
ized individually. A distinction is made here between the following parameters:
Parameter Description
System parameters Global system functions for the
complete CPX terminal
Module parameters Module and channel-specific functions
of the respective module
Diagnostic memory Operating method of the diagnostic
parameters memory
Tab. 3.9
A detailed description of the individual parameters as well as basic principles of applica­
tion can be found in the CPX system description (è P.BE-CPX-SYS-...).
Which parameters stand for the modules used are found in the description for the re­
spective module.
Caution
If the Modify-LED (M) lights up permanently, the parameterisation is not stored locally in
the bus node and is not restored automatically by the higher-order system upon re­
placement.
• In these cases, check before replacement to see which settings are required and
carry out these settings.
Changes in parameterisation or application-specific parameter settings result in
changes to the module or system behaviour.
• Check especially when replacing CPX terminals to see which settings are necessary
and make sure that these are restored, if necessary (e.g. by appropriate system-
start parameterisation).
Warning
The connected actuators can move unexpectedly!
Modification of the signal statuses and parameters can trigger dangerous movements of
the connected actuator technology.
• Make sure that nobody is in the positioning range of connected actuators, and be
very careful with the parameterisation or manipulation of signal statuses.
• Always note the instructions relating to "Force", "Idle Mode"and "Fail Safe"in the
CPX system description (è P.BE-CPX-SYS-...), in the description for the CPX-MMI
(è P.BE-CPX-MMI-1-...) and in the online help for the CPX-FMT.
