 Hello,

Perhaps this is not the best way to use a  binary signal for the EN signal to initialize and call a block.In this manner when you disable the input , previous status is kept in the IDB related to each instance .I suggest to manage initialization, automatic or manual operation or even a reset procedure inside the FB and keep the Enable signal always active.If this is not your case, please explain more.

I hope this helps,

Hi

I share Mr. Hosseini opinion. I have not gone through your coding, but I would however guess to make a design suggestion.

Consider using an FC with IN-OUT parameters. You can have several calls to the same FC (just like you had with the FB) but have the FC calls share the resources used in the IN-OUT, so that these data keep on being current.

If however you use for example timers in the FB you designed, then my idea will not help you - but then also not yours. For this case you need to rethink your coding structure.
