GICSP Encyclopedia v2 Question and answers rated A+ 2024 Industrial Control System (ICS) - correct answer A device or set of devices that managed commands directs or regulates the behaviour or other devices or system, bridges cyber to physical, a device that can influence the real world Relays - correct answer An electrically operated switch. Complicated to configure cumbersome and expensive Pneumatics - correct answer The technique of using gases for power transmission. Control Loops - correct answer calculating and controlling an environment or process based on feedback. Proportional Integral Derivative (PID) - correct answer a control loop feedback mechanism (controller) widely used in industrial control systems. Calculates an error value as the difference between a measured process variable and a desired setpoint. Proportional - correct answer The PID value that produces an output value that is proportional to the current error value. The proportional response can be adjusted by multiplying the error by a constant Kp, called the proportional gain constant. Integral - correct answer The PID value that is proportional to both the magnitude of the error and the duration of the error. In a PID controller, it is the sum of the instantaneous error over time and gives the accumulated offset that should have been corrected previously. The accumulated error is then multiplied by the integral gain (K_i) and added to the controller output. Derivative - correct answer This PID value in the process error is calculated by determining the slope of the error over time and multiplying this rate of change by the derivative gain Kd. The magnitude of the contribution of the derivative term to the overall control action is termed the gain. Fuzzy Logic - correct answer The degrees of truth, Truth Value between 0 and 1 for various factors. Values used to determine final operation
