Lesson 2.1

Trace, classify, hand off

EIKON microblocks are 401's function blocks in ALC dialect — rich PID and logic families, traced output-backwards like everywhere.
The live program view in WebCTRL shows values on the diagram — watch the logic think; the trace instrument is built in.
The thermographic view accelerates 302's remote diagnosis: the comfort landscape and its deviation patterns appear before you read a single point.
Loop shapes on WebCTRL trends diagnose identically (401); priorities answer ignored commands (306), alongside ALC's lock/override indications.
Boundary: read the live programs freely; EIKON edits belong with certified programmers — cite program and block path in the handoff.

Service boundary: EIKON edits belong with ALC-certified programmers — your live-view trace with block paths makes the certified fix a ten-minute job.

LAB — the mixed-building drill

Identification: from the evidence pack (photos, screens, board labels), identify the Automated Logic generation and architecture present.
Navigation: on the demo/simulated front end, locate a given point, its trend, its schedule, and its override state within a time box.
Reading: trace one supplied program excerpt against its sequence (expected/observed/delta per 303) and classify the seeded deviation: equipment vs programming vs design.
Handoff: write the service note a Automated Logic-certified tech could act on immediately.

Pass: identification correct; navigation within the box; deviation classified with reasoning; handoff note professional.
