TIAN // field notes for automation engineers
Field notes on PLCs, control systems, and the software that runs real machines. Written between callouts.
Read the latestWhat TIAN is
A working logbook for people who automate real machines. Every entry started as a real problem on a live line, and it's written to be used on your next shift — not admired.
Examples come from real lines and real failures, not vendor slide decks.
Numbers, timings, and tolerances stated plainly — copy them straight into your project.
Patterns chosen because they survive maintenance, handover, and the next engineer.
