Hi, I have a similar need.
I use different models of Unistreams and would like to connect fingerprint scanners in stead of using the screen login.
The finger print scanner I have in mind can either produce a single logic (relay contact, single DI) or 2 x DI to provide 4 levels of security.
Is it possible to manipulate the User Access Control Struct in Ladder based in a combination of digital inputs?
fbojan, Flex is heading into explaining that you have fallen into the trap of "always having the latest", when in fact if it isn't broken, don't change it! (This is the reason why the Vision system has Version Swapper, but such a thing doesn't exist for U90.)
You need to use/download the U90 version you wrote the original program with and also use that to correct the OS to the correct one. The download area lists these under Previous Versions.
Many people have an area of their program that specifies exactly what they used at the time. Some have it showing on screens, some in a hidden location that is consistent b/n all jobs.
