Password protect code

Hi, I am new to this forum.
I have been experiementing with plcnext for the first time to assess it’s suitability for multi site installations. ie. I plan to install units in multiple remote sites, with a PLCNext at each site.
Can anyone advise if there is a way to password protect the code in the PLC and the HMI?
Thank you

Hi subcom,
afaik there is no project password. If you are looking for know how protection you can release your code as a restricted library. Meaning you can see the programs, function etc. in the application but you cannot open them to see the code inside.

Hello subcom,
to protect the code running on a remote site you could use our licensing mechanism.
(this way the Code will only execute IF there is a License installed this license is hardware bound.)
You just need to embed the LICENSE_STATUS FB into your project and install a license.

Regardless how you secure the code I would recommending bundling the finished application as an app to easily setup multiple PLCs with the same application. This can contain everything from configuration to projects etc.
