Function
The product, as a station in an PROFINET IO network, establishes the connection between a higher-
order controller and the modules of an automation system CPX-AP-A.
Data are transferred based on Industrial Ethernet following the IEEE 802.3 protocol. Communication
takes place in real-time, using the Real-Time Protocol (RT) or the Isochronous Real-Time Protocol (IRT).
The product has two equivalent Ethernet interfaces with integrated switch, and therefore supports
both star and line topology. The network can be divided into segments using additional switches and
routers.
Device description file
A device description file (GSDML file) is used for project engineering of the PROFINET interface in the
higher-order controller software.
It contains all the information required for parameterisation of the automation system CPX-AP-A via
control software.
The device description file is available at the Festo Support Portal
