hello I have a question, 
I work with LOGO! Soft Comfort and 
I want to stop the display of data (a speed given by a sensor) 
on a LOGO TDE display when a sensor contact is activated

for example the speed sensor is on 100 rpm and the sensor 
contact activates so I want it to matter whether the 
engine goes up or down I want that if the second 
sensor activates the speed remains fixed I get to that deactivation

thanks you

trad with google

so I will try to use a clearer example

first of all I have 1 sensor:
a speed analog sensor
and a button

the speed sensor controls the speed of an electric motor and displays it on a display

I want that when I press the button the speed indicated by the display remains that of the moment I pressed the button

regardless of what the sensor says

yes it s this 

a very big thanks you
