Fundamentals of the KEB-Powerlink connection

The KEB-F5-Powerlink operator contains a separate Powerlink slave controller for processing of time-critical
communication tasks. An extensive Powerlink compatibility is also ensured by using this external component. The
supported Powerlink versions are EPL V1 and EPL V2.

3.1.1 EPL-Command-Layer protocol(parameter channel)

The Command-Layer-protocol' is supported by the KEB-F5-Powerlink operator. Thus it is possible to address any
parameter itself in the FI control and in the Powerlink operator via acyclic SDO protocol. The supported services
on the "COMMAND Layer" are:
• Expedited Download Transfer with Write-by-Index as Server (writing of a parameter via index, subindex)
• Expedited Upload Transfer with Read-by-Index as Server (reading of a parameter via index, subindex)
Parameter-addressing with 16-Bit index plus 8-Bit subindex
1.Index Last index
1000h 1FFFh
2000h 5FFFh
6000h 9FFFh
(*1): The KEB parameter address can be found here or in [3]. It is also possible to display the KEB parameter
address in the KEB start-up software COMBIVIS. See annex for specific informations.
