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'd like to use same code/project in different devices. (RPi, PLC) I change some lines in some POU before compiling. (array size, file path, etc ) My question is How to define pragma that effects all ST-POU in project. Is it possible ? I've read this. https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_pragma_conditional/
