Password Screen on NT Support Tool

[Guest Chido]

Hi everybody, does anyone know how to protect a screen with a password? I am using NT series Support Tool Ver. 4.6 to program a NTC31. In the main screen I have touch buttons that call other screens that I want to password protect. Thanks for you help

Password protection is not directly available in NT series. You can put a screen in between with e.g. a 4-digit thumbnail entry that is assigned a DM, and a button that triggers a compare instruction in the PLC, which compares the thumnail setting with a fixed number or another DM (the password), if they equal you @MOV the screen number in the PT control area. On release of the button (negated contact) you @MOV 0000 in the thumbnail DM to hide the password entry. That's how I always do it. *PDL is confusing thumbnail with thumbwheel Edited 24 Feb 2005 by PdL
