According to IEC, the wire end can be tagged with three things.
Where it came from (termination), the Signal (which everyone here is equating to the wire number) and where it is going to (termination).
It does not have to have all three; it should at least have the where it is going to.
The termination number shall include all information about where it is going/came from; Tag number and terminal number.
For example, the wire going to relay 5001K1 on terminal A1 would be labeled [5001k1:A1]
This also applies to terminal strips; the wire going to TS10 terminal 5 is labeled [TS10:5]
You can even assign which side of the terminal the wire is connected to by adding for example 1 for top and 2 for bottom. Then the tag becomes [TS10:5.1]
I spent about three months becoming familiar with IEC format when a previous company switched over. Initially there was resistance but over time everyone became used to it and ended up liking it better than the "old way."
One of the big benefits comes when you have to replace a component; you can easily swap out a drive without having to refer to a schematic since all the wires are labeled with where they are supposed to go.
