Addressing, configuration and parameterisation
The address space of a CPX terminal in the PROFINET network
is limited. Determine the number of assigned inputs and out-
puts before commissioning or configuring the CPX terminal
(see section 2.2 regarding address assignment and section
2.3 regarding addressing).
Addressing of the individual modules is done by the higher-
order controller: PROFINET uses module-oriented addressing,
i.e. each module is addressed separately (in contrast to
block-oriented addressing of other fieldbus systems).
The controller uses the following for addressing:
– IP addresses and MAC-IDs
– fieldbus device names, in short Device Names.
Configuration of a CPX terminal and the related bus node
depends on the control system used. The fundamental pro-
cedure, PROFINET-specific preparations and the main config-
uration steps are depicted on the following pages (see sec-
tion 2.6).
A CPX terminal in the PROFINET network can be paramet-
erised through the control system (PLC/IPC), an operator unit
(CPX-MMI) or the Festo Maintenance Tool (CPX-FMT) (see sec-
tion 2.8).
