I'm converting 3 plc 5's to L72s. The first was converted last year using version 20. I used version 20 for this year's project, and had planned on using it for next year's conversion as well (for consistency); however, the current conversion included replacing one of the unit's VFDs with a powerflex 755 unit (it's a pretty sweet drive). I was told that version 24 integrates the drive with less hassle than the version I'm using, not that it was difficult with version 20.
The question is... is there a tangible benefit to upgrading the current conversion with a newer version of logix? If I do that then I'll likely want to convert last year's version 20 program up to the same version. The idea was to maintain consistency across the three units.
I'm a field guy and currently have versions 13 through 20 installed on my laptop. Based on what happened with version 16 (first scan bit) I like knowing that my coding won't exhibit any quirky behaviour due to unknown bugs. Version 16 bit me in the arse. I set up a routine to be placed in a certain mode whenever the processor is booted up (first scan), but found that the first scan bit kept triggering this mode. Needless to say this caused quite a few headaches. (that's when I found out that Rockwell's solution to this problem was to use one shots in place of the first scan bit... it's a non-fix fix).
Experiencing this firsthand once was enough for me.
