Managing Complexity

100 – 10,000 – 1mio – 100mio Lines of Code

Exponentially increasing complexity

PLCopen®


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

… software quality factors..

Failure Rates: difference between hardware and software

External Quality (‘Perceived value’) versus Internal Quality

Correctness, reliability, robustness, integrity, persistence,

safety

IEC 61131-3

Harmonizing the way people look to control

and now with the 3rd edition

TC1 Standards:the basis

PLCopen®


What is IEC 61131-3

Specifying an application program development environment

1 structuring tool - SFC

4 programming languages: 2 textual & 2 graphical

Program organization units for structuring and reuse

Strong data typing for error prevention

An introduction in IEC 61131-3 is given in a separate presentation

PLCopen on IEC 61131-3.pptx

PLCopen®


The 3rd edition includes Object Orientation

Why?

Main reason:To link better to the scared resources

of engineers in the future

The industry should better adopt to themthen vice versa

PLCopen®


Good news:

3rd edition fully compatible

with 2nd edition + extensionsThe OOP features are selectable

and usable over timeAnd many other enhancements

and proposals to demote – like for IL

PLCopen®

Logic Motion ControlSafety

PLCopen®


Reasons to merge – a changing environment

The tendency to move from one motor (master axis) to multiple axes, driven by mechatronic solutions;

The availability and acceptance of digital networks with safety functionality built-in;

The inherent move from hardwired safety functionalities to software solutions;

The increasing importance of safety related issues regarding personnel and machines (Governmental requirements )

TC3 - BenchmarkingA benchmark is a reproducible, portable test to measure the performance of a given system in

comparison to other systems

PLCopen®


Benchmarking (TC3)

Two different sets of benchmarks defined:

1. 5 different types of applications, which

are typical for the usage of a PLC.

2. Measures each language feature of the

IEC 61131-3 separately

PLCopen®


PC2 - Training

Important to create sufficient humanresources capable to create and innovate

PLCopen®


PLCopen Coding Guidelines: Goals

Overall: Increase the quality of the software for industrial

applications

How?: By defining a set of Rules, Coding Patterns and

Guidance on how to use them in Industrial Automation

PLCopen®


PLCopen Coding Guidelines - subgroups Coding Conventions (incl. Naming conventions and Rules) Software quality issues and software consistency Creating PLCopen compliant FBs (Design Pattern) Structuring and decomposition via SFC: do’s & don’t s Guidance for documentation in software programs Library usage Software Development Process
