Lesson 2: Ladder Logic, Timers, Counters, Sequences, and Analog Basics

Contacts, coils, branches, latches, edge detection, permissives, and interlocks
Timers, counters, compare, move, arithmetic, conversions, and simple reusable logic
Modes, state sequences, starts, stops, resets, alarms, and fault-recovery behavior
Analog ranges, scaling, normalization, filtering, limits, engineering units, and calibration
Watch tables, online tests, simulation, logic debugging, and documented test cases

Create or review a practical configuration for contacts, coils, branches, latches, edge detection, permissives, and interlocks.
Build and test an exercise involving timers, counters, compare, move, arithmetic, conversions, and simple reusable logic and modes, state sequences, starts, stops, resets, alarms, and fault-recovery behavior.
Use diagnostics or evidence to validate watch tables, online tests, simulation, logic debugging, and documented test cases.

Explain contacts, coils, branches, latches, edge detection, permissives, and interlocks.
Apply timers, counters, compare, move, arithmetic, conversions, and simple reusable logic and modes, state sequences, starts, stops, resets, alarms, and fault-recovery behavior.
Validate and troubleshoot watch tables, online tests, simulation, logic debugging, and documented test cases.
