Abstract
A communication slave used in a communication network system includes a control device, a capacitive element, a voltage determining portion, and a time measuring portion. The control device controls communication with a master. The capacitive element is coupled between a high-potential side bus and a low-potential side bus. The voltage determining portion determines whether a voltage between the buses exceeds a threshold voltage. The time measuring portion measures a time from when a charge of the capacitive element through the buses is started to when the voltage determining portion determines that the voltage exceeds the threshold voltage. The control device sets an ID value for communicating with the master based on a length of the time measured by the time measuring portion.
