Overview
This part of the documentation describes the connection and configuration of the motor controller
CMMP-AS-...-M3 in an EtherCAT network. It is intended for people who are already familiar with this
motor controller series and CANopen CiA 402.
The fieldbus system EtherCAT means “Ethernet for Controller and Automation Technology” and is man
aged and supported by the international EtherCAT Technology Group (ETG) organisation; it is designed
as an open technology, which is standardised by the International Electrotechnical Commission (IEC).
EtherCAT is a fieldbus system based on Ethernet and can be handled like a fieldbus, thanks to high
speed, flexible topology (line, tree, star) and simple configuration. The EtherCAT protocol is transported
with a special standardised Ethernet type directly in the Ethernet frame in accordance with IEEE802.3.
The slaves can broadcast, multicast and communicate laterally. For EtherCAT, the data exchange is
based on a pure hardware machine.

EtherCat-Interface CAMC-EC
The EtherCAT interface CAMC-EC allows the CMMP-AS-...-M3 motor controller to be connected to the
EtherCAT fieldbus system. Communication over the EtherCAT interface (IEEE 802.3u) takes place with
an EtherCAT standard cabling and is possible between the CMMP-AS-...-M3 from Revision 01 and the
FCT parameterisation software from Version 2.0.
Festo supports the CoE protocol (CANopen over EtherCAT) with the CMMP-AS-...-M3.
