Factory I/O v2.4.4 preview 2 available

[Edit] Released: Factory I/O v2.4.4

A second preview for the v2.4.4 version of Factory I/O is now available for download:

  • Installer (link removed)
  • Portable (link removed)

The main new features of this preview are:

  • Improvements to the OPC DA driver, restoring the ability to connect to RSLinx Classic.

  • A new option for the S7PLCSIM driver, allowing connection with S7PLCSIM Advanced V3.0. It can be enabled by selecting S7-1500 (S7-PLCSIM Advanced) from the Model dropdown.


    Version 3.0 of S7-PLCSIM Advanced is required, and the virtual PLC must be configured with an instance name set to factoryio.


  • New tutorial and sample available for S7-PLCSIM Advanced v3.0.

Feedback on these features is welcomed.

Great list of improvements!

Any chance you could add three simple objects?

  • A larger bin (like at least 4x the size of the gray bin)
  • Smaller parts (for source arrow to spit out, 1/4 the size of the lids would be great)
  • A generic machine we can put the source arrow inside?

These small changes would really help me integrate FactoryIO into my existing 8 courses at TheAutomationSchool.com.

Thanks as always,
