Wireless architecture and support for process control systems

A wireless communication system for use in a process environment uses mesh and possibly a combination of mesh and point-to-point communications to produce a wireless communication network that can be easily set up, configured, changed and monitored, thereby making a wireless communication network that is less expensive, and more robust and reliable. The wireless communication system allows virtual communication paths to be established and used within the process control system in a manner that is independent of the manner in which the wireless signals are sent between different wireless transmitting and receiving devices within the process plant, to thereby operate in a manner that is independent of the specific messages or virtual communication paths within the process plant. Still further, communication analysis tools are provided to enable a user or operator to view the operation of the wireless communication network to thereby analyze the ongoing operation of the wireless communications within the wireless communication network.

Communication analysis apparatus

To deal with user network communication activity which cannot easily and clearly be determined as problematic behavior, a behavior analysis apparatus 14 monitors communication between each user PC 16 in a domain 10 and Internet 20 via a gateway apparatus 12. For example, when there is a monitored item related to information leakage of the user in the detected communication, a weight value corresponding to the monitored item is added to a score concerning a possibility of the user leaking information. Subsequently, the scores are totaled and recorded for each unit of time. The behavior analysis apparatus 14 inputs data of time-series transition of the total value to a neural network which has performed learning for prediction processing, and predicts the possibility of the user's information leak at a time in the near future. When an increasing risk of leakage is predicted, the behavior analysis apparatus 14 communicates an alarm to a security manager.
