Certification Review | association news INTECH MAY/JUNE 2019 41 I n April, ISA provided operational technology (OT) training in support of the U.S. Army National Guard's national cyberoperations exercise, Cyber Shield. Cyber Shield 19, held at Camp Atterbury, Ind., brought together ap - proximately 800 Army and Air National Guard network defenders and world- class cybersecurity professionals, industry network owners, and others to train the next generation of cyberwarriors. "The training that soldiers and airmen obtained through Cyber Shield 19 and the National Guard adds to their ability to conduct their civilian jobs, and, vice versa, the training and experience they receive in their civilian positions strength - en the military's cyber capabilities. They become very valuable assets in protect- ing critical infrastructure," said George Battistelli, the Army National Guard Cyber- security program manager, information technology strategy division chief, and the Cyber Shield 19 exercise director. Cyber Shield includes a critical training component with courses and seminars organized into tracks based on the roles of the participating cyberteam members. "We focus on getting people prepared for cyberdefense," said Col. Teri Williams, commander, Cyber Shield 19. "There are a lot of people we bring to the table for that first week of training. Microsoft, CISCO, and SANS are on hand for some of the cy- berdefensive training. The International So- ciety of Automation provides ICS/SCADA network training. We also focus on the offensive side. Our belief is that the better that you are trained on the offensive side the stronger a defender you will be." ISA was selected by the National Guard because of its leadership and experience in developing the world's only consensus-based series of industrial cybersecurity standards, ISA/IEC 62443. These standards, which also serve as the basis for ISA cybersecurity training, pro- tect the industrial automation and con- trol systems and networks that operate OT machinery and associated devices within critical infrastructure. ■ ISA supports Cyber Shield ISA Certified Control Systems Technician (CCST) program CCST question As outlined in ANSI/ISA 5.1-2009, Instru- mentation Symbols and Identification, an instrument that is monitored on the control system HMI and is part of a safety instrumented system (SIS) loop would be represented by which type of symbol on a process and instrumentation diagram? A. A circle contained in a box with a hori- zontal dashed line through the circle. B. A hexagon with a double-dashed line through it, not contained in a box. C. A diamond contained in a box with a hor- izontal solid line through the diamond. D. There is no representation for a SIS in- strument given in ANSI/ISA 5.1-2009. ISA Certified Automation Professional (CAP) program CAP question In the first order process with dead time model (FOPDT), the process gain Kp is de- fined as: CAP answer The correct answer is D, Kp = change in process variable (in percent of range)/ change in controller output in (in percent of range). The process gain indicates the rela- tive change in process variable (PV) that results from the response to a change in the controller output (CO). Both PV and CO are expressed in percent of range to ensure the calculation is not dependent on the engineering units chosen. ■ Reference: Trevathan, Vernon L., A Guide to the Automation Body of Knowledge, Second Edition, ISA, 2006. CCST answer The correct answer is C, "A diamond con- tained in a box with a horizontal solid line through the diamond." The diamond symbol was first defined for safety instrumented systems with the release of ANSI/ISA 5.1-2009. Per previous releases, a box around the instrument "bubble" with a solid hori- zontal line through it indicates that the measurement or control element is nor- mally accessible to the operator from the main operator console, typically a human-machine interface (HMI) screen in modern control systems. ■ Reference: Goettsche, L. D. (Editor), Main- tenance of Instruments and Systems, Second Edition, ISA, 2005. A. Kp = change in controller output (in eng.units) change in process variable (in eng.units) B. Kp = change in controller output (in % of range) change in process variable (in % of range) C. Kp = change in process variable (in eng.units) change in controller output (in eng.units D. Kp = change in process variable (in % of range) change in controller output in (in % of range) Certified Automation Professionals (CAPs) are responsible for the direction, design, and deployment of systems and equipment for manufacturing and control systems. Certified Control System Technicians (CCSTs) calibrate, document, trouble- shoot, and repair/replace instrumenta- tion for systems that measure and con- trol level, temperature, pressure, flow, and other process variables.
