Post by timvh on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. 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.

I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Solved: I started from a fresh project and everything worked. I had a Function Block in the project at one point and deleted it. I think Codesys doesn't fully clean up on deletes.

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
Hello, For my program I need an extended pulse timer, which can be referred to as a retriggerable pulse timer. Where every rising edge of the input resets the elapsed time zero, extending the lenght of the output pulse. The Codesys pulse timer (TP) is a one-shot timer and only resets the elapsed time with the falling edge of the input. There is also a pulse timer (LTP) in codesys, but in my simulation it was also functioning as a one-shot even though the description sounds like LTP should be retriggerable. I have uploaded some timing plots from another PLC program for reference. I am looking for a timer equivalent to the "TEP" diagram. Is there an Extended Pulse Timer in Codesys? Maybe there is a way to manipulate the input so it resets the elapsed time outside the function block?
