1. A network cloud based simulation system for simulating operation of a process control network as connected within a process plant, the simulation system comprising: a local supervisor module at the process plant wherein the supervisor collects: a first state variable indicative of a current configuration of the process control network during an operation of the process control network and a second state variable indicative of an operation of a process during an operation of the process control network from the process plant; a remote simulation module communicatively coupled to the supervisor module wherein the remote simulation module comprises: a simulated process control network that uses one or more simulated process variable signals to produce one or more simulated control signals to a simulation of the operation of the process control network as connected within the process plant; a process model communicatively connected to the simulated process control network that uses the simulated control signals to produce the one or more simulated process variable signals; and an update module communicatively connected to the process control network to: periodically receive the first state variable indicative of a current configuration of the process control network during operation of the process control network from the supervisor module and to periodically receive the second state variable indicative of an operation of the process during operation of the process control network from the supervisor module, wherein the update module periodically configures the simulated process control network with the first state variable and wherein the update module periodically uses the second state variable to update the process model; a storage module communicatively coupled with the remote simulation module that stores: the first state variable at a point in time; the second state variable at the point in time; and simulation data representative of the simulation of the operation of the process control network that allows the simulation to be replayed and allows the simulation data to be subject to further analysis.
