Addressing global tags inside C functions

[UniProgramer123]

Hi,

I have been looking into the c function programming of Unilogic.

Can I address global tags of the solution inside the c function? 

If yes, is there a way to get for example System: "RTC time.Seconds" and other tags that might include 'space' char?

Transfer it as Function Input.

So, the answer is no then?

I noticed that if I do "Show structed text" in ladder I get a _op_op version of the tag.

If I use this code, for example System: "RTC time.Seconds" in the C function I can call and use it and it appears to work.

Am I breaking things by calling this code in C function?

Hi;

If you download the UniStream Examples  .zip file, there are several examples of how to import and use global variables within  C Functions.

The Examples   .zip file is just below the UniStream Download on the Unitronics Website.
