TIER 1 — MUST KNOW

  • PROFINET
  • PROFIBUS
  • Modbus RTU
  • Modbus TCP
  • EtherNet/IP

TIER 2 — IMPORTANT

  • OPC UA
  • Ethernet TCP/IP
  • RS-485

TIER 3 — GOOD AWARENESS

  • MQTT
  • CAN
  • CANopen
  • EtherCAT
  • DeviceNet
  • BACnet

Older protocols from the course

  • DF1
  • DH+
  • DH-485
  • PPI
  • MPI
  • NetDDE

PROFINET

  • IO Controller
  • IO Device
  • Device name
  • IP
  • GSDML
  • Diagnostics

PROFIBUS

  • DP master
  • DP slave
  • Station address
  • RS-485
  • Termination
  • GSD

EtherNet/IP

  • Scanner/controller

Practical Field Additions

  • PROFINET missing device, name mismatch and IP mismatch
  • PROFIBUS station address, termination and connector checks
  • Modbus timeouts, function codes, exception responses and byte order
  • EtherNet/IP device connection and adapter fault basics
  • Protocol fault-finding from physical layer to application
  • Recognize IEC 61850 as protection-substation communication (advanced awareness)
