Control Network / Control Project Automation

Solution

An automation system might contain a number of Control Networks representing different parts of a large plant.

Within each Control Network, you can create a number of Control Projects. A Control Project contains the configuration data for libraries, applications, connected hardware, etc.

Each application contains programs and additional objects (data types, function block types, control module types) that are used within the application.

Each program is connected to a task, which decides how often

the program is executed.

Declaration PanePOU Editor

The variables in the program are the holders of values. They are declared by giving each a name and by assigning a data type. Variables can be written in Microsoft Excel and then copied and pasted to the declaration pane of the POU editor.

Function blocks must be declared in the “Function Blocks” tab before they are used in the ST or IL languages (not necessary in the FBD or LD editors)

Different Places Synchronization

Libraries are handled in Library Structure and Object Structure.

Connected libraries are in the Application aspect of a specific application (such as Sxx_ReactorApp) in the Control Structure.

Data types, function block types and control module types are handled in the Object Structure.
