Courtesy: ISO 9506 Industrial automation system The development of the electronic amplifier during the 1920s, which was important for long-distance telephony, required a higher signal-to-noise ratio, which was solved by negative feedback noise cancellation. This and other telephony applications contributed to the control theory. In the 1940s and 1950s, German mathematician Irmgard Flügge-Lotz developed the theory of […]
Courtesy: ISO 9506 Industrial automation system Solenoid valves are widely used on compressed air or hydraulic fluid for powering actuators on mechanical components. While motors are used to supply continuous rotary motion, actuators are typically a better choice for intermittently creating a limited range of movement for a mechanical component, such as moving various mechanical arms, opening or closing valves, raising heavy press-rolls, applying pressure to presses. Computer […]

In open-loop control, the control action from the controller is independent of the “process output” (or “controlled process variable”). A good example of this is a central heating boiler controlled only by a […]
Courtesy: ISO 9506 Industrial Automation system Automation describes a wide range of technologies that reduce human intervention in processes, namely by predetermining decision criteria, subprocess relationships, and related actions, as well as embodying those predeterminations in machines. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices, and computers, usually in combination. Complicated systems, such as modern factories, airplanes, and […]

This focus or prioritization is part of the annual/ multi-year annual audit plan. The audit plan is typically proposed by the CAE (sometimes with several options or […]
Courtesy: ISO 9001 lead auditor training Under the COSO enterprise risk management (ERM) Framework, an organization’s strategy, operations, reporting, and compliance objectives all have associated strategic business risks – the negative outcomes resulting from internal and external events that inhibit the organization’s ability to achieve its objectives. Management assesses risk as part of the ordinary course of business […]

Although internal auditors are part of company management and paid by the company, the primary customer of internal audit activity is the entity charged with oversight of management’s activities. This is typically the audit committee, a sub-committee of the board […]

Other designations are available in certain countries. In the United States the professional standards of the Institute of Internal Auditors have […]

Over 30,000 auditors have been awarded professional certification since 1984 and more than 120 countries are represented on the IRCA register. Every year, […]
