Fingerprint reader in UniSream

[Don2015]

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

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?

Neels,

Yes, you can.

But it is so vulnerable, as digital inputs can be altered..

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?

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.
