Description of PLC Runtime System according to IEC 1131-3

All Program Organization Unit s (POU) - program, function block, function - are organized and handled from project tree

Definition of Global variablesand IO-configuration independent from POUs

User defined FunctionBlocks

1. Define FunctionBlock POU in project tree

2. Write FunctionBlock in any IEC programming language

3. Instances of user defined FunctionBlock

User defined data types STRUCT /ARRAY

1. Define required data type in own worksheet of project

2. Use data type in global variable declaration workseet if used for physical I/O

3. Use data type in variable declaration worksheet of POU

Single Editor for all Graphical Languages

Mix Ladder Diagram, Function Block Diagram and Sequential Function Chart in a single worksheet.

Benefits of IEC 1131.3• Standard project organization

• Standard Function Blocks

• Standard Functions

• Standard Operators

• Standard Data Types

• Standard programming languages

Startup Tools• Changes while process is active

• Breakpoints

• Forcing

• Overwriting

• Single Step

• Single Cycle

• Watch List
