Codesys TON Extension, doesn't run

Using Codesys 3.5 SP15



So I extended the standard TON function block as follows
http://www.plctalk.net/qanda/attachment.php?attachmentid=52942&stc=1&d=1577037174
The problem it doesn't run and I am really confused as to why



And then I create a wrapper around TON instead, like this
http://www.plctalk.net/qanda/attachment.php?attachmentid=52943&stc=1&d=1577037174
and the wrapper works fine


here is a video of them both "running" side by side

You replaced the function block call without calling the original function block.

In ST, you would add this line to your extended function block:
SUPER^();

Maybe in ladder you either insert an execute block and call SUPER^(); or insert a block with EN/ENO for SUPER^?

Thank you I didn't know I needed to call the base FB.



I created a BOX call and set the type to SUPER^


More Codesys questions coming. I am loving it so far. RS 5000 is icky.


I used Codesys 2.3 Years ago and liked it. Haven't had an opportunity to use 3.5 until now.
