Document Type and Number:
Japanese Patent JP2017200122
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve bidirectional communication in a facility communication system in which facility devices having different communication speed are connected.SOLUTION: A facility device is connected to a facility communication network including a first facility device supporting a first communication speed and a second facility device supporting a second communication speed. The facility device outputs, by communication at the first communication speed, communication information indicating start of communication with the second facility device at the second communication speed, switches a communication speed with a high-speed low-speed switching unit, outputs the communication information by using communication at the second communication speed, and outputs the communication information to the first facility device by the communication at the first communication speed.SELECTED DRAWING: Figure 5
