Store function not working

[JW0807]

Bit of a newbie to visilogic and PLCs in general, and am having an issue with store functions not working. 

Could someone point out my mistake?

Moved... to appropriate forum section

Standard problems:

-- MB47 and MB50 are not activated according to the program;

-- the piece of code you wrote lies in a routine that is never called anywhere;

--there is another place in the program where variables MI97 and MI116 are overwritten with another value or initialized.

 

If possible put your code here otherwise it's hard to tell where the problem lies.

P.S. What plc are you using and how do you test your code?

and as well....

--  Split this into 2 rungs,

-- Ensure that MB50 & 47 (and perhaps any other MBs that also dictate parameters) cannot be called at the same time...only one of them (all).

Re the "routine that is never called anywhere" noted by Kratmel, read this:

Fixed the issue. I had created a new subroutine just for that code, and I guess the program never called on that subroutine, so I moved it into the main subroutine and now it works fine. 

For future reference, how do you call up a subroutine? (I should probably read the help section 😁)

Yes 🙂

Hi JW0807

The example above show how to call subroutines when certain conditions are met.

The best way is to call subroutines without any condition.

Just connect the call subroutine block directly to the left rail without any condition.

This way the subroutine is always called.
