Detailed content

  • Memory:​ Flash firmware, battery-backed SRAM variables
  • Redundancy:​ Supports TMR/Simplex
  • Network:​ IONet to I/O packs, Ethernet to HMI
  • Supply:​ +5 V via backplane
  • Temperature:​ 0 °C to +60 °C
Functional Features:​ Deterministic scan, integrated fault logging, firmware rollback, triple-vote comparison in TMR.
Working Principle:​ Reads I/O table from network → executes application code → writes outputs → repeats every control frame (typically 10–40 ms).
Materials:​ Multilayer FR-4, ceramic decoupling, metal faceplate.
Installation:​ Insert in CPU slot; set node address via rotary switches; download application via ToolboxST.
Precautions:​ Always verify firmware revision matches project; do not expose board to static without wrist strap; replace battery within 5-year interval.
