How to define timers with Structured text?

I'm trying to create a TON-timer in simulink model and translate it to Structured text (codesys), but can't find any block to simulate TON-timer that works with structured text. I found corresponding from ladder logic generation https://www.mathworks.com/help/plccoder/ref/ton.html but this does not work with Structured Text.

Is there a block to implement this function?

Hello Tapio,

One option we have available is to use Stateflow and absolute time temporal logic constructs. When you specify target timer the generated structured text code contains target specific timer implmentation.
