As of mid-September, ANSI/ISA-100.11a-2011, "Wireless Systems for Industrial Automation: Process Control and Related Applications," has been unanimously approved by the International Electrotechnical Commission (IEC) as an international standard, and will be published by year end with the designation IEC 62734, according to the International Society of Automation (ISA).

Since its initial approval by the American National Standards Institute (ANSI) in 2011, ISA-100.11a-compliant devices have found wide global use, with more than 130,000 connected devices reported in 2012 and more than 1 billion hours of operational service at customer sites.

ISA-100.11a was originally developed with international collaboration following ISA's open consensus process as accredited by ANSI, which requires participation and voting by experts from multiple stakeholder groups including end users and suppliers. ISA100 voting members overwhelmingly voted to approve ISA-100.11a.

ISA-100.11a/IEC 62734 provides reliable and secure wireless operation for monitoring, alerting, supervisory control, open-loop control and closed-loop control applications. The standard defines the protocol suite, system management, gateways and security specifications for wireless connectivity with devices supporting limited power consumption requirements. The focus is to address the performance needs of process manufacturing applications, which include monitoring and process control where latencies on the order of 100 ms can be tolerated, with optional behavior for shorter latencies.

IEC 62734 uses Internet Protocol version 6 (IPv6), adheres to the OSI model and uses object technology—all necessary to support the industrial Internet of Things (IOT). In addition, the standard fully supports the ETSI EN 300 328 v1.8.1 European Union specification taking effect in 2015. Current industrial wireless products branded as ISA100 Wireless already meet this requirement.

IEC 62734 is supported by the ISA100 Wireless Compliance Institute (ISA100 WCI) under the ISA100 Wireless brand. ISA100 WCI conducts conformity assessment for ISA100 Wireless (IEC 62734) products, develops complementary specifications and facilitates collaboration in the ISA100 Wireless technical ecosystem.
