Step7 bit sets plc in stop

[Dentim]

Hi everyone,

For this project I would like to have an option to make a cpu315-2dp plc go into stop mode when a certain input is activated. So the PLC is in run and when i press this button the PLC goes into stop mode (all outputs are reset) and I need to reset the PLC via the switch on the cpu.

Is this possible?

thanks in advance

I think instead you make mres switch you can go to stop and run again by cpu switch

 

[Dentim]

Can you explain how I do this please? And i won't have to re-download my program to the PLC with this method?

There is a standard block called STOP.

Dont u ever first search from help?

Description

With SFC 46 "STP" (stop), you change the CPU to the STOP mode.

Hi all,

use the function SFC46 STP PGM_CNTL.
You can manage the STOP of the CPU by means the EN (enable instruction)using an input.

You'll find the SFC46 following the path Libraries==>stdlibs==>builtin

thanks, yes I searched in the Step7 help function but didn't found this fucntion. Now i have the following problem, when I try to put this function in my OB1 I get following error:
You want to insert a system function wich come from a library whose project version doesn't match with the version of the current project.

Is there any way to fix this?

Which library are you inserting it from ?

 

[Dentim]

from Libraries==>stdlibs==>builtin

 

[L D[AR2P#0.0]]

Use the Standard library

DON'T DO THIS! Jump around your code and write zero or whatever else you want to your outputs.

Just how do you propose to make the PLC run again.

Just how do you propose to make the PLC run again.

He already stated he wants to use the mode switch on the PLC for that.

Kind regards,

I understand what he wants to do...I just don't agree with it.

Nick, how can you not agree when you dont know why he wants to do it way he wants to do it.
