2.4.2. Set Up the Virtual Device

This Virtual Device function allows the user to simulate various devices with the real I/O. This function
includes the PID function. Proportional-Integral-Derivative control is the most widely used in industrial
control systems. A regulator which is controlled in accordance with Proportional, Integral and
Derivative is called PID control for short, also called PID regulator. When the user cannot fully grasp or
measure parameters of the control system, the PID regulator is the best solution.
A. PID Setting Example
In this section, we will describe the PID settings.
The user can also refer the Chapter 3. System Function Description - Section 3.5 Virture Device to
