name plc version 1.0.0 description PLC programming reference — ladder logic, structured text, function blocks, and IEC 61131-3 standards. Use when writing PLC programs, debugging rungs, or reviewing automation logic. author BytesAgain homepage https://bytesagain.com source https://github.com/bytesagain/ai-skills tags ["plc","industrial","automation","ladder-logic","iec-61131","structured-text"] category industrial PLC — Programmable Logic Controller Reference Quick-reference skill for PLC programming concepts, IEC 61131-3 languages, common instruction sets, and troubleshooting patterns. When to Use Writing or reviewing ladder logic programs Debugging PLC faults and I/O issues Choosing between Structured Text, Function Block, or Ladder Looking up IEC 61131-3 data types and timer/counter instructions Setting up communication protocols (Modbus, EtherNet/IP, Profinet) Commands intro scripts/script.sh intro Overview of PLC architecture — CPU, I/O modules, scan cycle, memory areas. languages scripts/script.sh languages IEC 61131-3 programming languages: Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), Instruction List (IL), Sequential Function Chart (SFC). instructions scripts/script.sh instructions Common PLC instructions — contacts, coils, timers (TON/TOF/TP), counters (CTU/CTD), math, comparison, move. datatypes scripts/script.sh datatypes IEC 61131-3 data types: BOOL, INT, DINT, REAL, STRING, TIME, arrays, structs. faults scripts/script.sh faults Common PLC fault codes and troubleshooting steps — CPU faults, I/O faults, communication errors. protocols scripts/script.sh protocols Industrial communication protocols — Modbus RTU/TCP, EtherNet/IP, Profinet, DeviceNet, OPC UA. examples scripts/script.sh examples Example programs: motor start/stop, traffic light sequence, tank level control, conveyor interlock. checklist scripts/script.sh checklist Pre-commissioning checklist — wiring, grounding, I/O mapping, safety circuit verification. help scripts/script.sh help version scripts/script.sh version Configuration Variable Description PLC_DIR Data directory (default: ~/.plc/) Powered by BytesAgain | bytesagain.com | hello@bytesagain.com
