This is not correct, because a function is initialised with every call.</p>
<p>The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.</p></div>Stack overflow with really simple function2024-09-19T12:28:00.294000Z2024-09-19T12:28:00.294000Zopineirohttps://forge.codesys.com/u/opineiro/https://forge.codesys.combc587e0f0e536edb0229f948818b7be8306fa98a<div class="markdown_content"><p>Hi and thanks for your reply.<br/>

I wouldn't call an FB from inside a FUN; it feels wrong to me.<br/>
I have had something <em>similar</em>. Try declaring the FB instances as GlobaVars rather than the instance memory.</p></div>Stack overflow with really simple function2024-09-16T09:27:45.691000Z2024-09-16T09:27:45.691000Zopineirohttps://forge.codesys.com/u/opineiro/https://forge.codesys.com5a8fbdf88a1e8ab6288e2e48f08073e4cc23f3cb<div class="markdown_content"><p>Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library.</p>
<p>I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error.<br/>
In detail it says: "<em>C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:</em>"</p>
<p>I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong?<br/>
Thanks!</p></div>
