3. Software3.1 Fundamentals of the KEB-Powerlink connectionThe KEB-F5-Powerlink operator contains a separate Powerlink slave controller for process-ing of time-critical communication tasks. An extensive Powerlink compatibility is also ensuredby using this external component. The supported Powerlink versions are EPL V1 and EPLV2.Technical data of the Powerlink interface:Supported Powerlink version(s) EPL V1, EPL V2Response Time 2 μs3.1.1 EPL-Command-Layer protocol(parameter channel)The Command-Layer-protocol’ is supported by the KEB-F5-Powerlink operator. Thus it ispossible to address any parameter itself in the FI control and in the Powerlink operator viaacyclic SDO protocol. The supported services on the "COMMAND Layer" are:• Expedited Download Transfer with Write-by-Index as Server (writing of a parameter viaindex, subindex)• Expedited Upload Transfer with Read-by-Index as Server (reading of a parameter via in-dex, subindex)Parameter-addressing with 16-Bit index plus 8-Bit subindex1.Index Last index Description1000h 1FFFh Communication parameter in accordance with [2]2000h 5FFFh Parameter of FI control and operator with index = KEB-Parameter-Address + 2000h(*1). KEB uses the subindex for set-addressing.6000h 9FFFh Parameter of the unit profile DSP402 in accordance with [4](*1): The KEB parameter address can be found here or in [3]. It is also possible to displaythe KEB parameter address in the KEB start-up software COMBIVIS. See annex for specificinformations.10Software
