Addressing global tags inside C functions

Recommended Posts

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?

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.
