4.10.7 Use of the Ethernet interface with EasyIP
For data transmission and control, the Compact Vision
Systems make the Festo EasyIP protocol available. This makes
communication possible with the following components:
– Festo controllers (e.g. CPX-FEC) with EasyIP support
– Festo FED with Ethernet connection
– Festo OPC Server
This allows very comprehensive output and control pos­
sibilities, such as for further processing of inspection results
in a higher-level controller.
Support for the EasyIP protocol by the Compact Vision
System must be enabled via the system parameters.
For communication via Ethernet, FEDs generally require a bus
interface (Ethernet interface). Further information on FEDs
(and if necessary bus interfaces) can be found in the descrip­
tions for the product concerned.
Reading and writing take place via the data packages defined
by EasyIP, whereby the data to be read/written are defined
through memory addresses.
The Compact Vision System not only makes I/Os available via
memory addresses, but also allows access to the results of a
check and to the settings of the system parameters.
Certain memory addresses can be both read and written to,
while others can only be read or only written to (

appendix A.6).
