PROFINET Checklist for Acceptance Tests

For several years, PI (PROFIBUS & PROFINET International) has been providing guidelines for planning, installation, and commissioning of PROFINET networks. These were used in day-to-day activities of many plant and machine builders as well as end users. Experts from end user groups, especially from the automotive industry, were actively involved in the development of these guideline documents right from the beginning. This had a very positive effect on the quality of the documents.

PN_guidelinesNow, these commissioning guidelines have been expanded on some points to include experiences gained through active collaboration with acceptance test service providers, as well. Accordingly, the new edition includes a detailed checklist that additionally specifies easy to use criteria for acceptance tests of PROFINET networks. These criteria can be easily verified with commonly used tools. Of course, support for such acceptance tests is provided for this by the PI Competence Centers, established worldwide, as well.

All in all, PI offers integrated and coherent communication solution packages from the basic specification to system maintenance. This is achieved through the active and continuous collaboration of its members.

The new guidelines are available in English and German and can be downloaded free of charge by all interested parties at:
