PLC HMI Named
PLC and HMI literacy names logic execution, I/O, and operator interface boundaries on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.

PLC HMI Named literacy. $OT_LAB only. Original Cyberlium.
Opening
PLCs run the process — literacy teaches defender monitoring points, not unauthorized logic downloads.
PLCs execute control logic on scan cycles; HMIs visualize and command with role permissions. Literacy covers logic integrity, firmware, USB maintenance ports, and separate engineering stations — never unauthorized downloads on live controllers. Cyberlium Topic 38 practices on $OT_LAB — YOUR fictional OT templates, zone diagrams, and labeled checklists under $HOME/cyberlium-lab/t38-ot/ no real-plant attacks, unauthorized OT scans, or exploit cookbooks. Next: Fundamentals Lab.
1. What PLC HMI Named covers (named)
PLC: ladder/function block logic, I/O modules, redundancy, firmware versioning. HMI: screens, alarms, acknowledge workflows, engineering vs runtime stations. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Write PLC/HMI pair row with fictional LAB-TAG-001 examples. Not stolen employer project files. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

PLC/HMI literacy — NAMED:
PLC: logic scan cycle, I/O modules, firmware version, change control
HMI: operator screens, alarms, separate engineering station
LAB tags: LAB-TAG-001 (fictional) — never live historian exports
Defense: monitor logic downloads; USB policy on engineering laptops

2. Why PLC HMI Named matters for defenders
Unauthorized logic changes are top OT incident causes. HMIs bridge IT phishing risks into OT. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Students draft PLC/HMI cards on lab templates. Production changes follow MOC and vendor procedures. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
3. $OT_LAB boundary
Forbidden: stealing live PLC programs. Allowed: fictional PLC/HMI literacy row with LAB tags. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

4. What you ship: plc hmi named card for $OT_LAB
PLC and HMI literacy names logic execution, I/O, and operator interface boundaries. $OT_LAB named. NEVER real-plant attack steps. chmod 600.
5. What you record before the next lesson
Date (UTC). PLC HMI Named card. $OT_LAB named. File t38-m02-l03-plc-hmi-named.txt chmod 600.
6. Wrong vs right: plant attacks vs YOUR OT lab sims
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Download employer PLC project file without ticket.
Right
Write plc hmi named card for YOUR $OT_LAB. Next: Fundamentals Lab.
Mission: document PLC HMI Named on YOUR OT lab
1) Name literacy rows on $OT_LAB. 2) Write NEVER list (no real-plant attacks, unauthorized OT scans, or exploit cookbooks). 3) chmod 600. Never scan or exploit real industrial networks.
