Siemens Logo + TD

Hello all

Im about to fit a Logo + Logo TD, it takes in a 4-Bit BCD input, in which i chooses certain timers to give pressure setting, depending what setting is set at that time the screen changes to present the relative infomation to the operators, I have fitted TD's before and used them for counting, i noticed that on the TD, the count values set points can be chaged easily, im not sure if this is the same for timers, but is there a way that i can stop people from changing these Counter/Timer set points from the TD Panel itself. Locking that page out some how???

Hi Nathan, welcome to the forum

open your logo program and double click on the timer you don,t want peole to change, the parameter box opens up for it, set protection active !! that should stop the value being changed on the TD.

Thanks john, i think i need my eyes checking for missing that. but i also meant is there away so that the operator cant go to any of the set up screens, i did a thing before where you had to Hold F1 & F4 down for 4 seconds to reset counts, is there away of doing this so i can get to another screen, where timer value can be changed, becuase although i dont want the operator to be able to change anything i would still like access to them through the TD??
