Device Names and Allocation \ of Addresses

The Communication Module CM5xy-ETHCAT acts as a master device in an EtherCAT® master-slave arrangement. It is connected to the Processor Module via an internal communication bus.

The Communication Interface Modules CI5xy-ETHCAT act as slave devices in an EtherCAT® master-slave arrangement. The slave devices are identified through their position in the bus segment. Address switches are not used. Thus it is possible to give the devices a specific name with a configuration tool before system activation.

The default settings of the EtherCAT® slaves need not to be changed before operation.

Caution

:strong:Risk of communication faults!

The device names are used to generate global variables for the PLC program. Each device names can only be used once within a network.

Make sure that all device names are unique.
