Abstract
A plurality of system control devices respectively include network interfaces for communicating with each other via a network. One of the plurality of system control devices functions as a master system control device, and the remaining system control devices function as slave system control devices. The master system control device transmits a control command to the slave system control devices by means of the network interface. The slave system control devices receive the control command by means of the network interfaces and supply an operation command to abatement devices in accordance with the control command. When unable to communicate with the master system control device, the slave system control devices either function as master system control devices or enter stand-alone operation mode.
