S7-SoftPLC:User SFC configuration
From IBHsoftec Wiki English
There is a possibility to add user defined SFC's/SFB's to S7-SoftPLC. S7-SoftPLC allows the user to use up to 100 DLLs with user defined system functions (SFC) or functions (FC). Every DLL can contain multiple SFCs or FCs. These SFC/FC can be created by the user in C++, if a certain specification is kept.
By integrating own SFC/FC, the function pool can be expanded by own application specific code parts (technology functions, know-how protection, special hardware components). If the blocks are transferred with the PU to the PLC, the PLC keeps the C++ created internal blocks.
Examples for creating own SFC/FC-DLLs are available at the IBHsoftec support.
