9 Commissioning
Note
Malfunction due to the higher-order controller and system CPX-E being switched
on in the incorrect order.
Switch on the higher-order controller and system CPX-E according to the
preset order of the network used.
1. Set up automation project for the higher-order controller with the help of the
corresponding software.
2. Load the device description file into the software è www.festo.com/sp.
3. Configure the system CPX-E in the software:
– System structure
– Network addressing
– I/O addressing
4. Transfer automation project to the higher-order controller.
Further information about commissioning the system CPX-E can be found
in the “Instructions for use of system CPX-E”. Information about the
