    • A process control system includes economic models disposed in communication with process control modules, as well as with sources of economic data, such as cost, throughput and profit data, and uses the economic models to determine useful economic parameters or information associated with the actual operation of the process plant at the time the plant is operating. The economic models can be used to provide financial statistics such as profitability, cost of manufactured product, etc. in real time based on the actual current operating state of the process and the business data associated with the finished product, raw materials, etc. These financial statistics can be used to drive alarms and alerts within the process network and be used as inputs to process plant optimizers, etc. to provide for better or more optimal control of the process and to provide a better understanding of the conditions which lead to maximum profitability of the plant.

    • A simulation system attaches to a configuration database for one or more fully configured nodes of a process control system and copies the modules within those nodes into one or more simulation computers as simulation modules. The simulation system includes an algorithm that automatically creates a reference parameter module for each of the copied nodes that stores a reference parameter for each of the inputs, outputs or other references to signals external to the nodes. In the case of the Fieldbus function blocks, the simulation system automatically creates a function block within the simulation workstation in the protocol of the controller node which mimics the operation of the Fieldbus function block, and then creates the simulation system having those mimicked Fieldbus function blocks operating as if they had originally been configured to be in the controller being simulated, instead of within a field device external to the controller.
    • 仿真系统连接到过程控制系统的一个或多个完全配置的节点的配置数据库,并将这些节点内的模块复制到一个或多个仿真计算机作为模拟模块。 仿真系统包括一种算法,该算法为每个复制节点自动创建参考参数模块,该参考参数模块存储每个输入,输出或其他对节点外部信号的引用参考。 在现场总线功能块的情况下,模拟系统在仿真工作站内自动创建模拟现场总线功能块操作的控制器节点协议中的功能块,然后创建具有模拟现场总线功能块的仿真系统 操作就好像它们最初被配置为正在模拟的控制器中,而不是在控制器外部的现场设备中。

    • Smart process objects, which have both graphical and simulation elements, may be used to create one or more graphic displays and one or more process simulation modules, each having elements which may communicate with one another and with devices within a process plant to model and depict the operation of a process plant. The smart process objects may include one or more device objects, which represent physical devices within the process plant, and may include one or more smart connection objects which represent and model the flow of a material, such as a gas, a liquid, a composition of solid, electricity, etc., through a connection between entities within the process plant. The smart process objects may also include one or more smart stream objects, which also may represent and model the flow of a material at a particular point in the process plant. The smart device, connection, and stream objects may be interconnected to model the flow of material through the actual physical devices within the process plant thereby enabling enhanced simulation and modeling capabilities with the smart connection and stream objects providing a convenient manner of enabling different entities and sections of a process model to be tied to one another.
