Automation Week 2012

From an owner’s perspective, selecting automation technology for any process or plant represents a myriad of choices. These choices range from large-scale choices such selecting the automation platform (i.e., whether to use a DCS, a collection of PLCs/RTUs, vendor package control systems, or a combination thereof) to tiny details such as what color should be used to represent a pump running in “local mode” on a computer screen in the control room. When these choices are made on a project to project basis or left up to system integrators involved with individual projects, the end result can often be a wide range of incompatible and inconsistent technologies that get installed over time. This is not preferable as it can lead to higher long-term maintenance and training costs, as well as ongoing/recurring issues with integration complexity, usability and user interface consistency.
This paper will discuss the benefits of automation master planning from the perspective of a facility owner. Automation Master Planning, also referred to as SCADA Master Planning in some industries, is the process of working with facility stakeholders to determine both short and long term automation goals. These goals are captured in the form of a “living document” called an Automation Master Plan, which is then used to guide the use of automation technology for all of the owner’s facilities.
The role of developing “facility automation standards” to support the Automation Master Plan will also be discussed. Facility automation standards are different from published industry standards, as they are written for the sole purpose of reflecting owner’s specific needs and preferences. They are typically developed in house, reference external standards as needed, and provide specific guidance on exactly how automation is to be implemented in all of the owner’s facilities. Facility standards can be very hardware/software specific or they can be performance based – their content and format depends entirely on the individual facility owner’s preferences. At a minimum they typically consist of standardized specification documents, code libraries, and sample programs, as well as drawing and document templates. In the paper, guidance will be provided on how to set up a facility automation standards program in conjunction with automation master planning, and how successfully apply facility automation standards to the capital projects workflow. The paper concludes with case studies of several municipal water/wastewater utilities that have successfully implemented their own facility automation standards in conjunction with automation master plans.
