Channel-based order
The CoE directory is located in EtherCAT devices that usually encompass several functionally equivalent
channels. e.g. a 4-channel 0 – 10 V analog input terminal also has 4 logical channels and thus 4 identical
sets of parameter data for the channels. In order to avoid having to list each channel in the documentation,
the placeholder "n" tends to be used for the individual channel numbers.
In the CoE system 16 indices, each with 255 subindices, are generally sufficient for representing all channel
parameters. The channel-based order is therefore arranged in 16

steps. The parameter range x8000
exemplifies this:
• Channel 0: parameter range x8000:00 ... x800F:255
• Channel 1: parameter range x8010:00 ... x801F:255
• Channel 2: parameter range x8020:00 ... x802F:255
• …
This is generally written as x80n0. Detailed information on the CoE interface can be found in the
