ANSI/ISA-100.11a-2011, “Wireless Systems for Industrial Automation: Process Control and Related Applications,” gained unanimous approval from the International Electrotechnical Commission (IEC) as an international standard.
By the end of this year, IEC will publish the standard as IEC 62734.
Since its initial approval by the American National Standards Institute (ANSI) in 2011, ISA-100.11a compliant devices have seen action across the globe, with over 130,000 connected devices reported in 2012 alone, and over 1 billion hours of service at user sites.
ISA-100.11a originally developed via international collaboration following the International Society of Automation’s (ISA) open consensus process as accredited by ANSI, which requires participation and voting by experts from multiple stakeholder groups including end-users in addition to suppliers — ensuring all views and needs end up taken into account. ISA100 voting members, including those from end-user companies deploying wireless systems in real-world industrial applications, voted to approve ISA-100.11a.
The goal behind ISA-100.11a/IEC 62734 is to provide 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 performance needs of process manufacturing applications, which include monitoring and process control where latencies on the order of 100 ms can end up tolerated, with optional behavior for shorter latencies.
IEC 62734 utilizes Internet Protocol version 6 (IPv6), adheres to the OSI model and uses object technology.
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 has support from 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.
