PackSoft Application Library

• common software elements
• builds a standard for programming commonly used
  functional elements
• builds on existing standards wherever possible

• OMAC PWG PackSoft FB Library
• Machine control generics
• Communication elementary functions

PLCopen FB for Motion control
PLCopen Extensions for Motion Control
Future useful standards
6
PackSoft Application Library

• PackSoft AL common software elements
• builds a standard for programming commonly used
  functional elements
• Definition of an application library for
  Packaging
• Definition of interfaces and functionality,
• Use of Pack WG Tag Names
• Implementation is technology specific and
  therefore NOT scope of work
• Application Library should become a commonly
  used elements collection
• Use of generic standards, e.g. PLCopen

7
PackSoft Application Library

• Definition of Software means
• PackSoft defines
• PackSoft DOES NOT
• Define Implementation, Architecture, Technology
  of Software
• Write Software, create software deliverables
  etc...

8
PackALExample

• Wind / Unwind as Pack-specific version of gear
  function
• Makes use of generic existing standard FB
  GearIn
• Builds specific function
• Uses Pack-specific tag names

Gear ratio exists as PLCopen MC standard FB
MC_GearIn
9
PackALExample

• Function Block use Tag Names of OMAC PWG
• Mandatory IO variables and
• optional IO variables
• Reference variables allow for various technology
  implementations
• Use of specific OMAC PWG tag names
• FB can be called in any language (LD, FBD, SFC,
  ST, IL of IEC61131, C, etc.)

10
PackALExample

• Function Block description
• State Diagram graphics

State Diagram describes software execution
Graphics explains process
11
PackALElements

• Collection of functional machining elements

12
PackALElements (cont.)

• Collection of Communciation primitives

13
PackSoft ALCall for Participation

• Deliver suggestions for generic functional
  elements in Packaging!
• Join PackSoft
• Participate actively in refining the draft to
  ver. 1.0

14
PackSoft Objectives 2004

• Define the interfaces and behavior of code
  elements,
• for machine application, machine elements,
  machine communication,
• leave the implementation on specific technology
  (central versus distributed, PLC versus PC versus
  drive contained) to the vendors and their
  respective users,
• allow for differentiation of implementations by
  following the good practice of PLCopen in
  handling the issues
• Integrate and relate to work of other OMAC PW
  Committees

15
PackSoft Objectives 2004

• develop a clear understanding what compliance
  and use of the PlugPack logo means and develop a
  policy
• make use of pre-existing and emerging new
  standards that show to be useful in packaging
  before re-inventing the wheel.
• have deliverables of a library by middle of 2004,
  tbd. during the Orlando meeting
