Frequently Asked Questions
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
Does it run in a virtual machine?
Yes, VMware or VirtualBox work for programming and testing; enable nested acceleration if you use the built-in simulator.
Can older projects be opened?
Projects migrate forward release by release. Keep a backup copy of the original project before converting it to a newer version.
Which controller series is supported?
Check the release notes for the exact firmware matrix; each major version supports a defined controller range, and newer firmware usually requires a newer engineering tool.

Tips from Real Projects
On a recent line-commissioning job, CX ONE 4.40 ran beside the physical controller for the first two weeks of startup, and every logic edit was proven offline before it touched steel. Two disciplines carried the project: library blocks versioned and tested on one pilot station before any update-all sweep, and trace files kept running so intermittent faults left evidence. One caution from the field: never convert an old project without keeping the untouched original beside it — some migrations are one-way doors.
