What is the role of CC-Link Terminal resistor  ？

The terminal resistor is to eliminate signal reflection in the communication cable. During the communication process, there are two reasons for signal reflection: impedance discontinuity and impedance mismatch. The impedance is discontinuous. The signal suddenly encounters little or no cable impedance at the end of the transmission line. The signal will cause reflection at this place. The principle of signal reflection is similar to the reflection of light from one medium into another. To eliminate this reflection, a terminal resistor with the same size as the characteristic impedance of the cable must be connected across the end of the cable to make the impedance of the cable continuous. Since the signal transmission on the cable is bidirectional, a terminal resistor of the same size can be connected across the other end of the communication cable.
