Abstract
Disclosed is a system for transmitting and receiving safety information, which generates first safety information about a control target and second safety information representing the occurrence or not of an error in the control target by using one microcontroller. The system includes a first slave controller generating first safety information and second safety information by using sensing data obtained from a control target and a master controller receiving the first safety information and the second safety information from the first slave controller through a wireless channel. When an error occurs in the first slave controller, the first slave controller transmits the second safety information to a second slave controller, and the second slave controller transmits the second safety information, received from the first slave controller, to the master controller.
