Short Desciption:
This document is the third part of a set of documents of the PLCopen Task Force Motion Control. Currently, the set consists of 5
documents:
• Part 1 – Basics Function Blocks for Motion Control
• Part 2 – Extensions
• Part 3 – User Guidelines
• Part 4 – Coordinated Motion
• Part 5 – Homing Procedures
The first two parts are released.
This document is released on an on-going basis. With every release new examples are added. The first release was as version 0.3,
in April 2004. The second release in April 2008 as Version 0.4.
Summary:
General
This document is the third part of a set of documents of the PLCopen Task Force Motion Control. Currently, the set consists of 5
documents:
• Part 1 – Basics Function Blocks for Motion Control
• Part 2 – Extensions
• Part 3 – User Guidelines
• Part 4 – Coordinated Motion
• Part 5 – Homing Procedures
The first two parts are released.
This document is released on an on-going basis. With every release new examples are added. The first release was as version 0.3,
in April 2004. The second release in April 2008 as Version 0.4.
1.1. Objectives
To define a set of examples and clarification for user of the other PLCopen Motion Control documents.
This is not intended as an IEC 61131-3 tutorial – basic understanding of IEC 61131-3 is seen as a pre-requisite.
These examples are to be seen as examples only – they have not been tested in practice on real implementations.
1.2. User Derived Function Blocks
The IEC 61131-3 defines Program Organization Units, POUs, consisting of Function, Function Blocks and Programs. Within
this concept, a user can generate own libraries of POUs. Of particular interest are the User Derived Libraries of Function Blocks.
Within such a library, a user identifies the reusable parts of an application program, created with the standard available POUs, as
well as with the PLCopen Motion Control Function Blocks.
This document shows how a user can generate an own library, dedicated to their own application area. By creating such a library,
and making it available throughout their organization, one can save a tremendous amount of time in the next project. Moreover,
the usage of own libraries enhance the readability and transparency of the application programs generated.
