When you create a CFC chart, a run-time group is created automatically and has the same name as the chart. You can assign attributes to the run-time group that decide the scan rate of the OB cycle and the phase offset with which the blocks are executed.

What's new in SIMATIC STEP 7 CFC in TIA Portal V19? With SIMATIC STEP 7 CFC V19, further improvements have been made to the stability and performance. The new list of CFC tag interconnections in the "Chart sequence & extras" editor supports you in searching for interconnected operands.

CFC (Continuous Function Chart) 连续功能图是 PCS7 的必备组件，也是 STEP7 的高级语言选件。 CFC 编程界面为图形界面。 用户在 Chart 中通过鼠标拖拽的方式插入已经编制好的功能块（来自系统功能库或用户自己通过 STL/FBD/LAD 开发好的 FB， FC 等)，并指定这些块之间的连接关系，也可以为这些块分配输入输出地址。 作为用户导向的高级语言， CFC 程序需要通过“ Compile ”编译方式生成实际的机器语言程序（OB 、 FB 、 FC 等），并通过 CFC 下载选项将程序装 …

“CFC”代表“Continuous Function Chart”。 使用 CFC，可通过在 CFC 图表中执行简单的放置、参数分配以及指令和块的互连操作来创建用户程序。 CFC相比于其它语言，它能够清楚地表明信号之间的逻辑关系 以行李传送…

CFC (Continuous Function Chart) is an editor with a graphical user interface, an extension based on the STEP 7 software package. It is used to create the entire software structure of the CPU and uses pre-configured blocks.

2024年11月12日 · 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.

The theory -- what are CFC charts and what is the CFC editor? The overall process of a plant is described by continuous sequences. For this purpose, you must create CFCs in the CFC editor of PCS 7. You create CFCs by inserting blocks from the PCS 7 Library Vxx into the CFCs.

Hierarchical CFC charts and standard CFC charts have an interface structure that is similar to that of blocks. This means that these CFC charts can be configured and interconnected externally similar to blocks.

The Continuous Function Chart (CFC) implementation language is a graphical programming language and extends the standard IEC 61131-3 languages. You can insert and freely position elements in a programming block in CFC.

The "Getting Started" documentation provides quick instructions for first-time users to acquaint them with the CFC program package. An tutorial is divided into several tasks and guides you step-by-step from the simples configuration work to the creation of a chart with chart I/Os and the generation of the block in the CFC.
