Pretty close to what I use. But what are your thoughts on the naming convention as it pertains to CoDeSys 2.3 vs V3 and making things some what backwards compatible in a way (Since many people like myself develope on both and we all had to start at 2.3 first). In other words V2.3 is what especially prompted this naming convention since variable types where not visible in V2.3 but are in V3.0? Same with hovering over the variable in V2.3 you only see the comment not the type as you do in V3. I would just like to get your opinion on this as although V3 has many new features (thankfully) I still carry through the same naming convention I use.

It is not part of 61131 nor from PLCOpen
However it is used, nowadays it is not that important anymore as when you hover over a name it will show you what type and where it is.
Here is a file from Lenze with names.
I try to use these (not always i am not perfect)
