Ladder

Version: 1.3.0.0

Highlights of this release:

  • Customizable toolbox – add your own items and access frequently used blocks directly
  • Improved parallel branches – insert markers on hover, clearer parallel insert commands, new Show Insert Positions toggle (Ctrl+Shift+M), plus several reliability fixes for closing branches
  • EN/ENO compile fixes – MOVE and operator boxes (ADD, AND, MUL, OR, SEL, SUB, XOR) with EN but without ENO now compile as expected (relevant after LDFBD → LD2 conversion)
  • Editor fixes – Unicode/CJK variable names no longer truncated; negated contacts colored correctly in online view; accurate error locations on NC contacts and transitions; connected inputs and outputs preserved on FB type change
  • Stability – crash on block type change, Project Compare Allow Single exception, and cross-reference list freeze all resolved
  • Hardened PLCopenXML import/export – FBs without EN/ENO pins, edge-detection modifiers, schema ordering issues
  • File-Based Storage support for LD2 POUs (requires SP22 + File-Based Storage 1.0.0.0)
