Step3: Device settings [BayDevice_CH*, Coupler No_CH*]

CH1 and CH7: are assigned on 'Feeder', so Feeder is set for the [BayDevice_CH1] and
[BayDevice_CH7]. The settings [Coupler_No_CH1] and [Coupler_No_CH7] are left with
default number '1', because they are not applied here.
CH2 and CH3: are assigned on 'West coupler', whereas CH4† is assigned on 'North
Section'; CH5† and CH6† are assigned on 'South Section'. Therefore, Coupler is set for the
[BayDevice_CH2] to [BayDevice_CH6].
Coupler Numbers: West/North/South Couplers have to be identified by numbers uniquely.
The examples illustrate that '1', '2', and '3' are set for the [Coupler_No_CH2] to
[Coupler_No_CH6], but there is no rule to define the numbers.
[Coupler No_CH2], [Coupler No_CH3]=1 (at West Coupler)
[Coupler No_CH4]=2 (at North Section)
[Coupler No_CH5], [CH name_CH6]=3 (at South Section)
CH8 to CH24: The [BayDevice_CH*] and the [Coupler No_CH*] are left with default Non
setting and default number '1'.
