B.1 Access to internal parameters and data
The CPX terminal permits access to internally saved data and
parameters. The ways in which you can access these data and
parameters depend on the fieldbus protocol used. For
example access can be made via:
ć The plug−in module or scanner/bus master; e.g. for guarĆ
anteeing the desired parametrisation of the CPX terminal
in the start−up phase or after fieldbus interruptions
ć Fieldbus−specific configurators, e.g. during the commisĆ
sioning phase or during a search for faults
ć The user program in the higher−order PLC/IPC, e.g. for
modifying parameters or system features during operĆ
ation
ć The handheld, e.g. during the commissioning phase or
during a search for faults
ć The I/O diagnostic interface, e.g. for reading out diagnosĆ
tic data.
Data can be read. Parameters can be read and modified.
Only read access to parameters and data by means of the
relevant function number is possible via the I/O diagnostic
interface (see section 5.2.2).
