How does the tag name option work for the c-more pushbutton passwords. location of my question: PUSHBUTTON password option tab- configure password button- using the tag Name radio option. Does the v-memory tag name for the password have to already equal a vaule and then the person has to type that value to enter in? If so then this didn't seem to work for me. Where am i going wrong?

timjan2005, we use the tag option for the password. This allows the value in a PLC V-memory location to be the password for that object, rather than the fixed value programmed with the C-more software. Using this option (rather than the fixed value) for the password allows the supervisor to change the password when/if needed, without the C-more software.
Keep in mind the password function is not applicable to momentary push buttons. You can use the password function with a switch, and you can simulate a momentary function by using the SET and RST instructions. Hope this helps.

This did help.
Here is what i'm trying to attempt.
Users with passwords:
Engineer
Manager
Supervisor
Operator
I'm wanting the Engineer to see all do all.
and then the manager would see almost all and on down to where the
operator sees the least.
Is there an easy way to do this?

timjan2005, when you say "Engineer to see all do all ", etc. you mean you do not want the operator to even see the object, as well as the object being password-protected by the higher-level password?
There are a lot of ways, but one way is to use screen-change buttons that are pass-word protected, and assign your passwords so only the people that you want to have access can change to those screens.
You can even use a tree structure so a group could change to a screen with other screen-change buttons, then a smaller group would need passwords to change to another screen with other screen-change buttons, etc.
You can assign multiple passwords to an object. Assign Engineer and Manager passwords for example, so the engineer and manager can access the object (or screen) with the respective passwords, but others without those passwords cannot access the object (or screen).
We found it is helpful to allow the operators to see, but not access certain setpoints, so they know what to expect from the machine.

timjan2005, another thought, although I tend to use other methods, like the one mentioned above, I worked with a guy that Loved the visibility option, and used it in many creative (and sometimes confusing to me) ways.
