PROBLEM TO BE SOLVED: To provide a dynamic zoning plant system capable of preventing incident damage from expanding while ensuring early recovery, by changing the network connection of the apparatus of a plant.SOLUTION: A dynamic zoning plant system has a LAN switching device 71, a local controller group monitoring device 72, and a LAN branch device 73 between an IT system 3 and a local controller group 5, and includes a LAN switching system 7 for changing the configuration of the network of the local controller group 5 dynamically. Furthermore, a field bus 62 between the local controller group 5 and a field apparatus group 6, is provided with a field bus switching system 8 having a field bus switching device 81, a field apparatus monitoring device 82, and a field bus branch device 83, and changing the configuration of a network connecting the local controller group 5 and field apparatus group 6 dynamically.SELECTED DRAWING: Figure 1 |
