Project Tree Structure
All Program Organization Unit s
(POU) - program, function block,
function - are organized and
handled from project tree
Description of PLC Runtime
System according to IEC 1131-3
Definition of Global variables
and IO-configuration
independent from POUs
All instances within one resource
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.
