Don2015 Posted February 16, 2018 Report Share Posted February 16, 2018 HI, I now have my first UniStream PLC, and I'm wondering if it is possible to connect a fingerprint reader to it? Thanks, Don Quote Link to comment Share on other sites More sharing options...

Neels Posted August 20, 2019 Report Share Posted August 20, 2019 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? Quote Link to comment Share on other sites More sharing options...
AlexUT Posted August 20, 2019 Report Share Posted August 20, 2019 Neels, Yes, you can. But it is so vulnerable, as digital inputs can be altered.. B.R. Quote Link to comment Share on other sites More sharing options...
Neels Posted August 20, 2019 Report Share Posted August 20, 2019 Alex 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? NP Quote Link to comment Share on other sites More sharing options...
AlexUT Posted August 21, 2019 Report Share Posted August 21, 2019 Hi Neels, Download UniStream Examples from Unitronics Support Site and use "UniStream_070_Password_Access.ulpr" project. Use different Digital Inputs instead of "Password 1 Entered", "Password 2 Entered", "Password 3 Entered" tags. *Modify example as you need. B.R.
