The ISA112 SCADA Systems standards committee is actively developing a series of ISA standards and technical reports for Supervisory Control and Data Acquisition (SCADA) systems. Established in 2016, the committee now has over 200 SCADA experts from around the world representing a wide range of industries. Led by two volunteer co-chairs, the committee strives to have an even balance between: end-users, vendors, distributors, consultants, engineering firms, contractors, system integrators, government regulators, and other interested parties. As part of an ANSI-accredited standards development organization (SDO), membership in the ISA112 SCADA standards committee is open to all interested individuals.

ISA112 Scope

Develop a series of ISA standards and technical reports that address system design, implementation, operation, and maintenance of SCADA systems for pipelines, water and wastewater, power, oil and gas, and other industries to support the overall integrity and reliability of these systems.

ISA112 Purpose

The standards and technical reports will provide guidance on how to design, implement, operate and maintain SCADA systems by documenting best practices in a range of industries. The anticipated plan is to develop one or more standards to be supplemented by technical reports expanding on implementation details and industry-specific guidelines.

Committee Membership

Like all ISA standards committees, the ISA112 Systems Standards Committee is open to all interested parties. The ISA112 committee leadership strives to have an even balance between: end-users, vendors, distributors, consultants, engineering firms, contractors, system integrators, government regulators, and other interested parties. The committee also enjoys broad membership across many industry sectors, including: oil/gas, pipelines, mining, pulp and paper, chemical industry, environmental monitoring, and the municipal water sector. At present, the ISA112 committee has over 200 SCADA experts from around the world who regularly participate in the committee's activities. Individuals interested in joining the ISA112 committee as information members are welcome to contact one of the committee co-chairs, managing director, or our ISA staff contact listed below. All of the ISA112 committee members are volunteers.

Committee Leadership

Like all ISA standards committees, the ISA112 committee is lead by two volunteer committee co-chairs, who are in turn overseen by a volunteer managing director. Additional oversight is provided by the ISA's Standards and Practices Board.

The co-chairs are assisted by the ISA's professional staff, who provide provide the committee with collaboration tools and administrative support. The tools used by the committee include: an email discussion list (listserv), this website (www.isa.org/isa112), a document management tool (SharePoint), video/conference call hosting (MS Teams), and staff-managed software for managing the committee's membership roster.

Current Work Plan

Since its inception in 2016, the ISA112 committee uses a program of monthly conference calls (last Thursday of the Month) and semi-annual in-person meetings. The bulk of the committee's work is done offline by both the committee members and the co-chairs between the calls and meetings.  Due to the current global covid-19 pandemic, in-person ISA112 meetings have been suspended as of March 2020.  However, the monthly conference calls (and offline work by committee members) continues as scheduled.   ISA112's membership is comprised entirely of volunteers who donate their technical expertise towards the common goal of consensus-based technical standardization.
