hopping somebody can help, not sure if this has been spoke about before on here or not. 

please point me into the direction if it has. 

I'm looking at creating a user log on and password section.

Example - 

User Inputs User Code and password.  - the User code is then put into a VLOOKUP in the DB to find the associated password. if correct displays said users data. 

has anybody done/seen this before. I've generated it via Ladder but its very long winded and if it comes to having multi users (+50 its a lot of copy and paste). 



Thanks in advance.

You know this is a PLC forum right?  VLOOKUP is an Excel function.
