Product overview
5.1
Function
The product establishes, as a participant in an PROFINET IO network, the connection between a
higher-order controller and the modules of an automation system CPX-AP.
Data is transmitted on the basis of Industrial Ethernet following the IEEE 802.3 protocol. Communica-
tion 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.
This contains all the information required to parameterise the automation system CPX-AP via control
software.
The current device description file is available on the Festo Support Portal
è
Identification & Maintenance (I&M)
The “Identification and Maintenance” (I&M) function serves as an electronic rating plate of the inter-
face and offers uniform, manufacturer-independent access to device-specific online information over
the network.
PROFIenergy
The product supports the PROFIenergy profile for energy management. This makes it possible to
switch off specific consumers that are not required in order to reduce energy demand.
Crossover detection (auto MDI/MDI-X)
The product supports crossover detection (auto MDI/MDI-X), which means that there is the option of
using patch cables or crossover cables.
When using patch cables and crossover cables in the same network, crossover detection must be
activated in the higher-order controller.
Priority start-up (Fast Start-Up)
The "Fast Start-Up” function ensures that the automation system CPX-AP is able to start up quickly.
When using the “Fast Start-Up” function, crossover detection (auto MDI/MDI-X) must be deactivated.
