Frequently Asked Questions
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.
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.
Is a license dongle required?
Licensing is typically node-locked or dongle-based; a trial mode is usually available for evaluation.
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
A wastewater project delivered with S7 PLCSim V18 went from empty cabinet to accepted FAT in nine weeks, mostly because the offline work front-loaded the debugging. The habits that made the difference: one shared tag structure agreed before the first rung, every change tested in isolation, and a dated backup taken before each download. One caution from the field: let the consistency check finish before touching hardware configuration, or you will rebuild the compile tree twice.
