Mapping the Data to a NextMove e100

If you’ve followed this Application Note so far (and you have a Modbus/TCP client to use) then

you will have two process data objects being sent from the client/PLC to the MotiFlex drive

(mapped as NetData channels) and two process data objects being read by the client/PLC from

the MotiFlex drive (mapped as NetData channels).

The remainder of the Application Note shows how this data can be passed onto a NextMove e100

(via Ethernet Powerlink), effectively turning the drive into a Gateway between a Modbus/TCP

network and the Ethernet Powerlink network.

The diagram below illustrates this:

To achieve this transfer of data we must add the MotiFlex drive to the NextMove e100’s Device

Configuration File (DCF) and include the NetData channels in the list of additional Process Data to

be mapped between the NextMove and MotiFlex on the EPL network.
