Siemens Simatic STEP 7 CFC V17

The software developer Siemens Digital Industries Software is pleased to announce the availability of Simatic STEP 7 CFC V17. This Editor for Simatic S7-1500 can be used to interconnect function blocks as a continuous function chart (CFC) and therefore easily configure a signal flow diagram.

What's New in SIMATIC STEP 7 CFC in TIA Portal V17

CFC integration in TIA Portal V17
SIMATIC STEP 7 CFC V17 supports the S7-1500 CPUs as target systems.

TIA Portal provides users with a continuous engineering workflow and offers end-to-end standardization of automation through TIA Portal libraries that store tested modules for its user’s programs. TIA Portal also enables fully integrated engineering workflows based on the model of Continuous Integration, in which developers work as a coordinated team on automation projects.

Efficient engineering also means designing applications instead of programming them. Two new control program editors have been added to TIA Portal V17 for graphical configuration. The CFC Editor for Simatic S7-1500 can be used to interconnect function blocks as a continuous function chart (CFC) and therefore easily configure a signal flow diagram. This is especially valuable for users who already use CFCs in other projects and can now use the familiar program structure in TIA Portal as well.

You use SIMATIC STEP 7 CFC ("Continuous Function Chart") especially for process-control or structured automation solutions. With the SIMATIC STEP 7 CFC engineering software, you create automation applications using the graphical configuration of a technology chart, comparable to a function chart for PLC programming. With this graphical configuration, the blocks are arranged, parameterized and interconnected on a kind of "drawing sheet". You achieve this with the help of libraries that include pre-configured instructions and blocks. Thus, there is no need for programming the instructions and blocks which significantly reduces the error rate. In addition to convenient editing functions, the CFC scope of functions also includes powerful testing and commissioning functions.

For example, you interconnect blocks you have created yourself or instructions that were supplied by CFC to the operands of your target system. Even a complex user program remains manageable with the help of a CFC chart. Process values as well as input and output parameters of the instructions and blocks can be easily monitored online for testing.

In this movie we are going to model a process with CFC SIMATIC STEP 7.
