A process control simulation technique is created in a network cloud using data communicated from one or more plants using a thin or light client at the plant. The simulation performs real-time simulation or prediction of an actual process control network as that network is running within a process plant in a manner that is synchronized with the operation of the actual process control network. In particular, this synchronized simulation system is automatically updated periodically during the operation of the actual process control network to reflect changes made to the actual process control network, as well as to account for changes which occur within the plant itself, i.e., changes which require updating a process model used within the simulation system as the relevant data is communicated in a timely manner to the network computers operating in the network cloud. The synchronized, cloud based simulation system described herein provides for a more cost effective and usable simulation system, as the plant models used within the simulation system are synchronized with and up-to-date with respect to the current process operating conditions but the specialised knowledge to set up, operate and maintain the simulations are completed by trained operators in the network cloud. |
