All 127 OPC UA status codes, and what to do about each

A 15-page diagnostic reference grouping every normative status code by what actually went wrong: with the first action for each, and the four questions that resolve most faults before you read a single code.

• All 127 normative status codes, grouped by fault layer rather than alphabetically
• The first thing to do for every code, not just what it means
• The Bad / Uncertain / Good distinction that stops a dead sensor producing clean-looking data
