Frequently Asked Questions
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
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.
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.

Tips from Real Projects
During a packaging-plant retrofit, LOGO! Soft Comfort V8.3 paid for itself on the first night shift — three faults that would have stopped the line were caught in the office instead. What worked: force tables prepared before each FAT session, so scenarios could be demonstrated in seconds instead of argued about for hours. One caution from the field: keep the tool and firmware revisions matched to the target controller, or cross-loading a project will silently downgrade instructions.
