Fingerprint reader in UniSream


Recommended Posts

  • 1 year later...

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?

Security is not a problem as the panel is locked, I am merely looking at an easier and quicker login for operations...not all of us have swift fingers :)

What code would be able to write to the "User Access Control Struct" ? Or how do I affect a login from a DI?
