Guest Chido Posted February 24, 2005 Report Posted February 24, 2005 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 Quote
PdL Posted February 24, 2005 Report Posted February 24, 2005 (edited) 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 February 24, 2005 by PdL Quote
