International Standardization is an important foundation for product design, development and use. Standards underpin interoperability and guarantee consistent performance and high quality for end users.

PROFINET is standardized under a range of International Standards, the most important of which are:

• IEC 61158/61784-1 and -2 for the communication protocol
• IEC 61784-5 and IEC 61918 for connectors
• IEC 62439 for redundancy issues (MRP)
