Ontario Pipeline - Fall 2018 - 30

(standards developing organization), the
ISA has formed the ISA112 SCADA Systems
Standards Committee. The ISA112 committee has been charged with developing an international SCADA standard that
provides a set of minimum requirements
for the planning, design, construction, and
operation of SCADA systems.
Headed by two Canadian co-chairs, Ian
Verhappen from CIMA+ and Graham Nasby
from Guelph Water Services, the ISA112
committee now has over 150 members
from a wide cross-section of industries
that use SCADA technology. These include
municipal water/wastewater, mining, oil/
gas production, pipelines, environmental
monitoring, electricity transmission, and
telecommunications. One of the benefits
of having so many industries involved
is that good ideas from one industry
can cross-pollenate into others. There
are actually more similarities between
SCADA applications between industries
than there are differences. We are also
fortunate that the ISA112 committee has a
strong representation from the municipal
water sector, including several members
of our OWWA Automation Committee.
The ISA112 committee received its
charter from the ISA's Standards and
Practices board in 2016. Since that time
the committee has continued to grow, with
many members from around the world.
Currently the committee has members
from Canada, USA, England, Chile, Brazil,
Germany, Australia, and numerous other
countries. The committee also has a good
cross-section of end-users, utilities, vendors, consultants, contractors, and system
integrators. The committee has also made
a point of ensuring that the major SCADA

software vendors are involved, so that all
view-points are considered.
Membership of the ISA112 committee is
open to anyone with a SCADA background
who is interested in contributing. More
information on joining the ISA112 committee can be found at www.isa.org/isa112.
Most committee members contribute by
writing content, commenting on current
drafts by suggesting revisions, providing
examples to illustrate best practices, or
assisting with the resolution of submitted
comments and proposed revisions. The
committee itself holds monthly conference calls, which are supplemented by
face-to-face meetings twice per year. Much
of the writing/editing work is done offline
by committee members.
One of the main goals of the ISA112
committee has been to establish common SCADA terminology, architecture
models, and workflows to enable the
design, construction and operation of
SCADA systems to be done more efficiently, consistently, and robustly. Many
of the capital-project-oriented members
of the committee, are looking forward
to defining standardized SCADA terms
that can be used to more clearly define
requested features in SCADA specifications - to the benefit of both purchasers
of SCADA systems and to those to supply/
develop them. One of the current drafts
of the ISA112 SCADA architecture model
can be seen in Figure 1.
Another goal of the committee has been
to develop a standardized workflow, or
SCADA lifecycle, that provides an organized way to apply best practices in the
design, development, testing and operation SCADA systems. A major part of this

workflow is providing a consistent way in
which internal SCADA systems standards
can be organized. A copy of the current
draft of the ISA112 SCADA Lifecycle can be
found in Figure 2.
The ISA112 SCADA systems standards
committee has now been active just over
two years. In that time it has developed a
SCADA lifecycle model, reference architectures, and a draft table of contents for the
actual ISA112 SCADA standard. Presently,
the committee is in the midst of firming
up the table of contents, so the committee
members can set to work on writing first
drafts of the various sections of the main
document. The writing and editing phase
is expected to be very active for the next
two years, then to be followed by several
comment rounds where all committee
members will have a chance to further
refine/contribute to the document as it
takes shape.
As the ISA112 SCADA systems standard
develops, the OWWA Automation committee will be keeping a close eye on the ISA112
committee and its draft documents, both
to contribute some of our made-in-Ontario
know-how and to ensure that our Ontario
water community can make the best
use of this soon to be available SCADA
resource document.
