32 Studio 5000 ProTips for Machine Builders

I've been posting Studio 5000 and machine-builder ProTips for about a year. People kept asking for them in one place, so here's the running index. Built for OEMs, machine builders, and anyone living in Studio 5000.

1. Use NC sensors for overtravels (catch a failed switch before a crash)
2. Use PLC nonvolatile memory to commission machines without a laptop
3. FILL 0, length 1 to clear a UDT
4. Turn on hot keys and routine descriptions for fast programming
5. Group BOOLs in UDTs to save controller capacity
6. MOD for position math that survives encoder rollover
7. Buy the HMI screen protector and sensor guards (the top two field failures)
8. Never hard-code numbers. Use a constant tag for context and cross-reference
9. An AOI with a [1] InOut tag accepts any array length
10. Indirectly reference arrays AND DINTs (recipes, sequencers, input scans)
11. XPY to set a single bit position in a DINT
12. Fill a DINT with -1 to set all 32 bits (mask init)
13. Use the tag Style dropdown (binary, hex, ASCII) for readable intent
14. AOI Prescan to init tags, EnableInFalse to clean them up
15. A naming convention for temp bits (zzz plus initials) so they never ship
16. Run SIZE on first scan only
17. GSV the program or routine name straight to the HMI
18. Turn on ADC so a swapped VFD self-configures from its IP
19. T_Sync AOI to keep PLC time on NTP
20. Bookmark toolbar: the troubleshooting navigation trick
21. GSV WallClockTime for HMI timestamps
22. Minimize the motion group and IO config before going online (huge over VPN)
23. Array shifting, method 1: reverse shift (memory-safe)
24. Array shifting, method 2: copy-copy (insert anywhere)
25. The two hidden Studio 5000 menus (module status and AOP version)
26. The $ string escape character
27. Read motion error codes and wrap them in an AOI and faceplate
28. Multi-Version Download and a shared basket for new hires
29. IO mapping is a must: scan consistency and one-line hardware fixes (full post)
30. Wire labels left-to-right, top-to-bottom, always
31. TRN to split the whole number from the decimal
32. Don't copy/paste-tune rigidly geared servos (they'll fight and hum)
