My personal Conclusion: even so there is a standard, however not adhered to at all or in parts, as well as many problems regarding interoperability you will not see me interested!
You change the meaning again.
The fact is that many devices (the same roco Z21 detector) were designed before their manufacturers joined the RailCommunity association.
The RCN-217 was not created from scratch, as the basis was Standart RailCom Lenz 1.4, which in turn is based on NMRA 9.3.2.
Accordingly, all RailCom-enabled devices created prior to the introduction of RCN-217 are based on Lenz 1.4 or NMRA 9.3.2. Although basically all of these standards are fully compatible.
In the end, as I understand it, the foundations of the RailCom problem are not standards or hardware problems.
The problem, as Bulgakov wrote in the disembodied "Dog Heart" - "Devastation in the Heads." The fact is that railway modeling is an age hobby, and, accordingly, people are not ready for changes and something new. For many, DCC is already a problem, not to mention Railcom or computer control.
