Hi,

you can use SFC 46 "STP".

Kind regards
Stefan

What you are looking for is the STP instruction.
See the image as implemented in Step7 (TIA), which will look the same in Step7 Classic.

The STL code is how it will look like if you want to make it able to convert to LAD.

Be VERY careful how you implement the function as to not create a dangerous situation for the machine user.

Hello all,

really very strange question from Topic user about use this control mechanism. User need after that  to do Warm restart??? Really I'm curious what background is here and what is real reason to do that...
