Finding where SFC is used in program

8/18/2022 8:15 PM	Rate (0)
Dkrills Posts: 14 Rating: (0)	CPU 319-3 PN/DP S7 manager . Very new to siemens S7. Is there a way to find what block or fucntions an SFC is used in without searching all of them. We have 16 vfd drives that are controlled over profibus and will be updating them to profinet. Need to find them in the program guessing theyre being communicated with via SFC14 and SCF 15. Just not sure were many blocks in this program. Thanks in advance

This is described in the Programming with Step 7 v5.6 manual, section 14. https://support.industry.siemens.com/cs/ca/en/view/109751825 See also this following short video on how to use the Reference Data in a S7 program. https://youtu.be/3Ur1LGCQaUE Hope this helps, Daniel Chartier Attachment Cross references.jpg (432 Downloads)
