Abstract
(EN)
A distributed control apparatus of the present invention comprises: a plurality of slave devices connected to a network master by means of a serial or ring network; and a real-time compensation means for performing a first operation for guaranteeing real-timeness when initializing each of the slave devices, and a second operation for guaranteeing the real-timeness of each of the slave devices in consideration of changed time information when a ring connection is made as the network connection at a certain location is lost.
