1 PLCopen ® for efficiency in automation PLCopen Motion Control an introduction Check the notes in the notes view

2 PLCopen ® for efficiency in automation PLCopen Motion Control: The software problem

3 PLCopen ® for efficiency in automation

4 PLCopen ® for efficiency in automation Managing Complexity 100 – 10,000 – 1mio – 100mio Lines of Code Exponentially increasing complexity

5 PLCopen ® for efficiency in automation Why Structured Software Development ?  Software = key to system quality: errors cost money  Increased requirements: 100 lines of codes now 10,000 lines or even 100,000  Not a one-man job - but a team with different know how and background  Commissioning, Installation, Maintenance, and Improvements essential phases

6 PLCopen ® for efficiency in automation Modern Software Development Process  Defined in several clearly separated phases - project definition  Top-down approach  Multiple disciplines involved  Multiple people involved  Different backgrounds  Based on Functional Requirements

7 PLCopen ® for efficiency in automation Decomposition with Sequential Function Chart SFC

8 PLCopen ® for efficiency in automation Bottom-up after top-down Top- down Bottom up First decompose – then fill it in
