Sysmac I/O Link v1.2.0

Sysmac I/O Link v1.2.0

This release focuses on making the application safer and clearer for students. Common setup and mapping mistakes now show friendly validation messages instead of Python traceback pop-ups or unclear bridge crashes.

What's New

• Added friendlier app-level error handling for common student mistakes.
• Added stronger validation before starting the bridge.
• Bridge start is now blocked when mappings, globals, backend settings, addresses, duplicate mappings, or Sysmac datatypes are invalid.
• Bridge runtime errors now identify the failing mapping, for example: input:bit:5 -> S1.
• Damaged or invalid configuration JSON files now show clearer messages.
• Sysmac globals used by mapped variables must include datatype information.
• Packaged builds suppress the PyInstaller traceback dialog by default.

Important Globals Change

Use the full Sysmac export table:

Tools -> Export Global Variables -> CX-Designer

Paste the full exported table into the app's Globals setup.

Plain variable-name lists are no longer enough for mapped variables because the bridge needs datatypes to pack values correctly.

Sysmac I/O Link v1.1.0

Highlights

• Added explicit Factory backend selection: SDK or Modbus TCP
• Removed automatic backend fallback mode
• Added backend-aware connection tests and bridge start checks
• Added Modbus type validation in mappings (prevents unsupported types)
• Added Modbus TCP PoC server script for communication testing
• Updated manuals and GIF guide with backend/addressing behavior

Factory backend behavior

• SDK: uses Factory I/O SDK memory map (Ultimate workflow)
• Modbus TCP: uses Factory I/O Modbus TCP addresses from driver mapping
• Mapping address is interpreted by the selected backend

Requirements

• Windows 10/11
• Factory I/O (SDK backend for Ultimate, or Modbus TCP backend)
• Omron Sysmac Studio with Simulator

Installation

• Download Sysmac-IO-Link.exe from Releases
• Run the application (no installer required)
