Remove Protection on floats micrologix 1400 lcd screen

2 posts in this topic

Hi,

 

I'm writing a short code to deduce the speed of a rotor using the time it takes between pulses of a rotation sensor, and use this value to determine if it is underspeed/ overspeed / correct - the program seems to be working fine but there are variables which I'd like to be able to edit. There might not be a HMI for all of the application we will use this program in so I was going to edit the float values directly from the modify menu on the LCD screen - the issue I'm having is that I can modify Bool values etc but when I try to modify a float I cant change the value as there is "Protected!" text - how can I remove this?

 

Picture attached.
