CFC are "blocks" interconnected with signals. Is that what you are looking at ?

Besides, for GRAPH, SCL, and CFC, you cant just upload from the PLC if you dont have the source code. If you dont have the source code, the program will display in STL.

hanung,

With CFC charts it is impossible to upload the original charts from the PLC. If you make an upload you will only get the compiled STL code which is useless.

You need to have the original S7 program to make changes in the CFC charts.
