How to Use SIMATIC CFC V8.0 for Process Control Systems
SIMATIC CFC V8.0 is a software tool that allows you to create and edit continuous function charts (CFCs) for process control systems. CFCs are graphical representations of control functions that can be executed on different devices, such as programmable logic controllers (PLCs), distributed control systems (DCS), or human-machine interfaces (HMIs).
In this article, you will learn how to use SIMATIC CFC V8.0 for designing and implementing CFCs for your process control system. You will also learn about the latest updates and features of SIMATIC CFC V8.0, such as integrated engineering with COMOS, bi-directional exchange of messages, and compatibility with SIMATIC PCS 7 V8.0.
What is SIMATIC CFC V8.0?
SIMATIC CFC V8.0 is a technological editor that is embedded in the standard engineering software of the SIMATIC PCS 7 V8.0 process control system. It allows you to create and edit CFCs in a graphical user interface, using predefined function blocks or custom blocks that you can create yourself. You can also import and export CFCs from other sources, such as STEP 7 or TIA Portal.
SIMATIC CFC V8.0 supports different types of CFCs, such as:
Global charts: These are CFCs that are executed on a central device, such as a PLC or a DCS.
Instance-specific charts: These are CFCs that are executed on a specific device instance, such as a valve or a pump.
Hierarchical charts: These are CFCs that contain other CFCs as subcharts, allowing you to create complex and modular control functions.
SIMATIC CFC V8.0 also supports different types of function blocks, such as:
Standard blocks: These are predefined function blocks that perform common control tasks, such as arithmetic operations, logic operations, timers, counters, etc.
Technology blocks: These are predefined function blocks that perform specific control tasks for certain technologies, such as PID controllers, motor starters, valves, etc.
User-defined blocks: These are custom function blocks that you can create yourself using the block editor or the block library.
How to Use SIMATIC CFC V8.0?
To use SIMATIC CFC V8.0, you need to have the following software installed on your computer:
SIMATIC PCS 7 V8.0: This is the process control system software that provides the engineering environment and the runtime environment for your process control system.
SIMATIC CFC V8.0: This is the technological editor that allows you to create and edit CFCs for your process control system.
SIMATIC NET: This is the communication software that allows you to connect your devices and transfer data between them.
To use SIMATIC CFC V8.0, you need to follow these steps:
Create a project in SIMATIC PCS 7 V8.0 and configure your devices and communication settings.
Open the SIMATIC CFC V8.0 editor from the SIMATIC PCS 7 V8.0 menu and create a new chart or open an existing chart.
Add function blocks to your chart and connect them with wires according to your control logic.
Assign parameters and variables to your function blocks and wires according to your control requirements.
Compile and download your chart to your devices and test your control function in the runtime environment.
What's New in SIMATIC CFC V8.0?
SIMATIC CFC V8.0 has been updated with several new features and improvements, such as:
Integrated Engineering with COMOS: This feature allows you to transfer instance-specific interlock circuits and bi-directional exchange of messages between SIMATIC PCS 7 V8.0 and COMOS V10.0, which is a software tool for plant engineering and lifecycle management.
Individual Control Units and Individual Control Types: This feature allows you to create individual control units and individual control types that contain hierarchical charts, which can be matched and exchanged between different projects.
Compatibility: This feature ensures that SIMATIC CFC V8.0 is 29c81ba772
