CONTROLLING COMMUNICATION AMONG MULTIPLE INDUSTRIAL CONTROL SYSTEMS
First Claim
1. A communication control system controlling communication among multiple industrial control systems connected via a network, the communication control system comprising:
- a communication relay apparatus for relaying communication between at least two of multiple industrial control systems;
a monitoring section for monitoring said multiple industrial control systems; and
a control section for switching, if said monitoring section detects an anomaly from at least one of said multiple industrial control systems, communication between an industrial control system detected with an anomaly and a second industrial control system so that said communication is performed via said communication relay apparatus.

Abstract
A communication control method and system for controlling communication among multiple industrial control systems connected via a network. The communication control system includes: a communication relay apparatus for relaying communication between at least two of multiple industrial control systems; a monitoring section for monitoring the multiple industrial control systems; and a control section for switching, if the monitoring section detects an anomaly from at least one of the multiple industrial control systems, communication between an industrial control system detected with an anomaly and a second industrial control system so that the communication is performed via the communication relay apparatus.
