HI again,
Yes, this is approximately what i want to do. to be more clear:
I have a data table containing username and password (10 row: 10 username with 1 password for each username)
What i Want to do now is:
-have an HMI on which you type in your username and password and press a button to start the check procedure
-it load the first row of the data table into a struct and try first to find a match of username.
-if there is a match of username, the idea is to check the password and give a feedback to the user depending on the result: (username not exist, wrong password …..)
-if there is no match with the first row, it load the second row into the struct and do the same procedure.
It does not sound very complex but really the "compare string" function would be perfect for this job.
In the meantime, I figure out what was going on with the disappearing tags, I upgraded unlogic to 1,3, rev10 and all tags came back automatically.
Can you let me know when the 1,4 version of unlogic will be available and where I can download the latest version available. only 1.2.5 is available on this website but I got the 1.3 rev 10 from my PLC supplier.
Best Regards
Guillaume
