<div class="markdown_content"><p>No problem.</p> <p>I had a quick look at one of my programs and there are some actions inherent to some code I have brought in for email etc.</p> <p>It appears to me they are all called from within the FB or POU that they are used in, not outside as you have displayed in your snip.</p> <p>I see you have called it directly after the FB, so can you not call it directly at the bottom from within the FB instead?</p> <p>I believe usually you could call the action from somewhere else, but as you mentioned yourself it does not pass any information, so perhaps the in_out var is causing it some confusion.</p> <p>A good test might be to try removing the in out parameter.</p></div>

<div class="markdown_content"><p>Thank you Ben for your reply!<br/> I initially wanted to use actions because i dont been to pass information in and out of the block. I believe this would have been "neater" but then i encountered this issue. </p> <p>I did try the assignment as you suggested "fbHomeSystems.ACTInit(stKineDataRef:=stKineDataRef)" however this did not work either. I have reverted back to using methods and it does seem to work fine barring afew warnings about externaly accessing an internal In_out parameter from an external method call.</p> <p>I just thought this was quite odd that codesys would have an issue like this in regards to actions but not methods.Wouldnt the assignment such as fbHomeSystems(stKineDataRef:=stKineDataRef);<br/> be carried out throughout the objects life during execution ?</p></div>

<div class="markdown_content"><p>Hey pal,</p> <p>Any reason you choose an action &amp; not a method?<br/> I have not used actions myself, but if it handle like an FB I believe it wants the IN_OUT to be nested in the calls brackets. ( EG. fbHomeSystems.ACTInit(stKineDataRef:=stKineDataRef); )</p> <p>You could try doubling up (being an in_out, I think it won't matter), or you could try only referencing it in the direct action rather than the call above, unless of course it is needed elsewhere in the FB.</p> <p>Let us know how that pans out.</p> <p>Cheers,<br/> Ben</p></div>

<div class="markdown_content"><p>Good Day</p> <p>Im having an issue that im hoping someone could help me with.<br/> I have created a function that uses an in_out variable. The function also contains actions.</p> <p>I then created an object from the function and assigned the in_Out variable before using the objects actions. However, when i try to call the objects actions it returns a "VAR_IN_OUT must be assigned when calling function". This is odd because is have already assigned the in_out parameter to the object before I used the object action.</p> <p>Im using codesys v3.5 sp19 </p> <p>any help would be very appreciated </p></div>
