SinaParaS (FB303) - Application examples

Gents,

I can't seem to find any application examples for acyclic profibus for G120x. I'm planning to use SinaParaS FB built in tia portal V15 with S7-1500 for reading an additional 80 real numbers outside my cyclic data.

Any code examples would be appreciated.

Cheers.

Hi 91-Club-Mate 

for handling so many values I highly recommend to use the LAcycCom library from here:

https://support.industry.siemens.com/cs/de/en/view/109479553

That library has the advantage of a so called "Resource manager FB". This block really handles the resources of the slaves (drives) and just communcates to them when they are ready for it. This is done automatically in the background so you do not need to care about the drive state. You just easily set your acyclic reading/writing request and the FB will handover the task to the resource manager. 

When using SINA_PARA FB you have to take care about the drive's resources yourself in the program.
