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
dec

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