The ISA Standards and Practices Board has approved the ISA-100.11a wireless standard, ‘Wireless Systems for Industrial Automation: Process Control and Related Applications’.

The approval of the standard by the ISA Board certifies that ISA-accredited procedures have been followed in the development of the standard.

The ISA-100.11a standard received final approval by the ISA100 committee in July, with 81 per cent of the voting members approving, before being passed along to the ISA S+P Board.

With the ISA S+P Board approval, the ISA-100.11a standard will be submitted to the American National Standards Institute (ANSI) for approval as an ANSI standard, and will be submitted to the International Electrotechnical Commission (IEC) for consideration as an IEC standard.

The ISA100 committee was established by ISA to address wireless manufacturing and control systems in areas including: the environment in which the wireless technology is deployed; technology and life cycle for wireless equipment and systems; and the application of wireless technology.

The standard is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open-loop control, and closed-loop control applications.

The standard defines the protocol suite, system management, gateway, and security specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting very limited power consumption requirements.

The application focus addresses the performance needs of applications such as monitoring and process control where latencies on the order of 100ms can be tolerated, with optional behaviour for shorter latency.

Pat Schweitzer, ISA100 co-chair, said: ‘to meet the needs of industrial wireless users and operators, the ISA-100.11a standard provides robustness in the presence of interference found in harsh industrial environments and with legacy non-ISA-100 compliant wireless systems.’ The standard addresses coexistence with other wireless devices anticipated in the industrial workspace, such as mobile phones and devices based on IEEE 802.11x, IEEE 802.15x, IEEE 802.16x, and other relevant standards.

The standard also allows for interoperability of ISA-100 devices.
