Programmable Logic Controller (PLC)
System Analysis
Normal Behavior
Continuously executes deterministic cyclic ladder logic/structured text (IEC 61131-3) to read sensor inputs and actuate valves, motors, and breakers.
Failure Behavior
Memory buffer overflows, firmware crashes, or corrupted logic uploads trigger watchdog timer trips or freeze outputs in dangerous states.
Business Consequence
Physical plant emergency shutdowns, mechanical equipment destruction, or environmental chemical release.
Visual Manifestation
"A flashing red FAULT LED on the PLC chassis, accompanied by immediate physical actuator lockouts across the factory floor."
Satirical Behavior
"A 500-dollar hardened brick that runs a ten-millisecond loop until someone uploads an unauthorized ladder rung at 2 AM to bypass a safety switch."

FAQ
How does it normally behave?
Continuously executes deterministic cyclic ladder logic/structured text (IEC 61131-3) to read sensor inputs and actuate valves, motors, and breakers.
How does it fail?
Memory buffer overflows, firmware crashes, or corrupted logic uploads trigger watchdog timer trips or freeze outputs in dangerous states.
What is the business consequence?
Physical plant emergency shutdowns, mechanical equipment destruction, or environmental chemical release.
What is a PLC scan cycle?
A deterministic three-step loop: 1. Read all physical inputs, 2. Execute program logic, 3. Update all physical outputs.
