you could use:https://store.codesys.com/codesys-contr ... __store=en
either 32Bit or 64Bit Version.
This is what your customer need to install.
In your real application you need to switch to this plc by 'update device' (right click in the device tree) - select the Control Win or Control Win64 plc.
Then next step is to login into your local installed Control Win ( should be the same either 64 or 32bit Version)
then you could extract from your machine the following content (use the whole drectory 'PlcLogic ' and copy this to the same location on your customers machine:
my path/locations for the 32 Bit Version(64 Bit you'll find in CODESYSControlWinV3x64
then the missing part is copy this file or only the section:c:\ProgramData\CODESYS\[b]CODESYSControlWinV3
This is for the runtime the Information which application Need to be started ( so in case your application has a different name in CODESYS this need to be adjusted here)
Now your customer hast a running demo without having CODESYS ( has only the plc now) and could
Play around. without license this runs for 2h.
(he starts manually the plc in the task tray, see screenshot to evaluate your Project, which then starts as Fullscreen HMI on his machine -> Alt-F4 to quit)
