EasyPLC 5 is distributed in two versions: DEMO and Registered.
The EasyPLC Demo is free and only allows you to use the simulated I/O device. This means you cannot communicate with commercial I/O devices or use the PC ports (serial, parallel, USB or Ethernet). This version is, however, free for personal use, but does not generate any economic benefit to the user/distributor of the software.
The Machines Simulator DEMO only allows you to use one demonstration machine, and the editor with which to create new machines is unavailable.
If you want to use EasyPLC for commercial purposes, utilize all the available drivers or write your own, use plugins, or create your own virtual machines to automatize, you need to buy a registration licence. Please go to Purchase & Price for details.
Before downloading and installing the software, you must read the EasyPLC licence terms and conditions, and only install it if you agree with the EasyPLC license usage.
