Worth noticing: NEMO traces conditions across Studio 5000 routines and uses a live-tag CSV to identify the condition holding a machine.

Field notes

The maker describes a day job leading maintenance and controls in manufacturing, with experience in mining, beer, and manufacturing. NEMO takes a Studio 5000 L5X export, lets the operator select an output or sequence step, then traces required conditions across routines; a CSV of live tag values helps identify the condition holding the machine. The cave atlas combines surveys with terrain LIDAR, geology, dye traces, streams, sinkholes, and trip reports.
