Siemens S7 & MicroMaster 4, Reading multiple parameters

Hi All,

Hope someone can help here! I have an S7-315 2DP and a MicroMaster440 talking on profibus. I have the basics fine and can read the speed, set the speed etc but am struggling with using SFC14 & 15 when it comes to reading certain parameters.

I need to read in about 7 different parameters to display on a screen and am struggling to find any documentation that explains this in an easy to understand way. I am assuming I will need to call SFC14 multiple times with different data but am struggling.

Any help greatly appreciated!

Have you tried this Siemens FAQ 8894584? It has numerous examples of reading parameters from a MicroMaster to a S7-317.
