WinPLC lock
« on: March 31, 2008, 09:19:48 PM »

I am developing a controls system with the Entivty/Think&Do WinPLC. I would like to "lock" the code down in the WinPLC. I can "lock" the WinPLC with the Entivity CE Watch utility; however, anyone can bypass the lock with DIP switch 1. Is there a way to really "lock" it via Host API calls? A way to pragmatically disable the DIP switch? Some other method?

Thanks for your help.

the winplc code that handles the dip switches is in a library that is statically linked into the entivity runtime, so there's no way to get around it with an external API call.

the best - and probably only way - realistically remove the dips from the get entivity to craft you a special version of their runtime that gives you the control you want.
Good design costs a lot. Bad design costs even more.

I believe the standard way to bypass a DIP switch is with an X-Acto knife.   ;D
