PLCopen releases Safety Specification part 2 – User Guidelines The
PLCopen Technical Committee 5 (TC5) Safety Software User Guidelines is a
reference for control people implementing safety control systems and is
available at no cost on the PLCopen WEB site (www.plcopen.org).
This is a companion publication to PLCopen Technical Committee 5 - Safety
Software Technical Specification; also available on the WEB site. This document
illustrates the ease of use of the defined function blocks in real life
applications. The
Safety Software User Guidelines document provides a wealth of information for
control engineers on safety applications including: Creating a Safety Plan,
Terms and Definitions, Example of Safety Functions in a Production Line,
Description of the PLCopen Function Blocks, PLCopen Function Blocks and
Connection to the Periphery, Graphical Overview of Safety Application Examples,
Use of Safe Drives, Diagnostics Concepts, Safe Motion with an I/O Interface, and
Two-Hand Control. The
independent association PLCopen, together with its members and external safety
related organizations, defined safety function blocks within the IEC 61131-3
development environments. Safety can now be implemented using a standard set of
function blocks. This supports the integration of logic and motion application
development with safety. This combination helps developers to integrate safety
related functionality into their systems, even from the beginning of the
development cycle. This approach contributes to the understanding of safety, as
well as reducing the certification time and costs. The
combination of logic, motion, and safety in one environment provides the user
with a harmonized view of the total application within one environment. And with
multiple implementations, this is also valid across platforms. This means less
educational efforts, and simpler transfer of knowledge and application software
between different controls. Also, it tackles the ‘not-invented-here
syndrome’, which often is a cause of errors and additional costs. By using
tested functionality, and support in the programming environment, including
language definition with subsets of functionality, one is able to create safety
related application programs for easy commissioning. ============================================== 2.
PLCopen XML – accepted by AutomationML The
PLCopen Technical Committee (TC6) - XML opened up the IEC 61131-3 development
environments by specifying the XML schema for this. As such it provides an open
interface to other software tools. PLCopen TC6 published their XML schema and
documentation in June 2005 as version 1.01. After that, feedback came in from
companies starting to implement this specification, not only from Europe but
also from Japan. With
a new initiative called AutomationML we have come to a new phase. The companies
Daimler, ABB, KUKA, Rockwell, Siemens, netAllied and Zühlke together with the
University of Karlsruhe and the University of Magdeburg jointly define and
standardize the Automation Markup Language (AutomationML™) as an intermediate
format for the Digital Factory. For more information check www.automationML.org. One
of the formats that have been accepted in this group is PLCopen XML for the
sequencing. In order to optimize this interface additional changes to the
specification are proposed. For
this reason the PLCopen members will meet again on May 6 at Mercedes Benz in
Sindelfingen, to support this new activity for TC6. The goal will be to update
the existing specification, including all accepted changes and proposals. If
you are interested in joining this meeting, just let us know. ============================================== 3.
Meet us at the Hanover Fair, PLCopen
has its booth during the upcoming Hanover Fair from April 21-25 in Hall 9 –
H68. Feel invited to step by at the booth and discuss your benefits in using the PLCopen specifications. Or
visit us to check the status of the specifications and the new PLCopen
activities, while enjoying a Dutch coffee, or drink one of the many beers from
all over the world to choose from while using your own PLCopener which you can keep as gift. Hope
to see you all at this event. ============================================== Kind
