Embodiment Construction

[0035] As discussed above, a process plant, process control system, or process control environment (which operates to control one or more industrial processes in real time when it is online) can utilize the novel techniques, systems, devices, components described herein during commissioning One or more of the , the apparatus and / or the method are communicatively connected. A process plant, when commissioned and operating online, includes one or more wired or wireless process control devices, components or elements that perform a physical function with a process control system to control one or more processes performed within the process plant. The process plant and / or process control system may include, for example, one or more wired communication networks and / or one or more wireless communication networks. Additionally, the process plant or control system may include centralized databases such as continuous, batch, asset management, historian, and other types of databases.

Abstract

Provide devices, systems, and methods to transmit data between the controller and multiple on -site devices in the process factory.The system includes a distributed marshal module, which is coupled from the front -end unit to an I / O card that communicates with the controller.The distributed group module communicates with the on -site device through the corresponding electronic packet components. The electronic packet component converts the signal between the on -site device and the I / O card.The distributed group module is coupled from the ring communication structure to the front -end unit, so that the distributed group module can be positioned as a relatively close -to -site device that is relatively close to its coupling.

Description

technical field [0001] The present disclosure relates generally to process plants and process control systems, and more particularly to the commissioning of field devices and loops of process plants and process control systems. Background technique [0002] Distributed process control systems (such as those used in chemical, petroleum or other process plants to manufacture, refine, convert, generate, or produce physical materials or products) typically include one or more process controllers, These process controllers are communicatively coupled to one or more field devices via analog, digital, or combined analog / digital buses, or via wireless communication links or networks. Field devices, which may be, for example, valves, valve positioners, switches, and transmitters (eg, temperature, pressure, level, and flow rate sensors) located within the process environment and typically perform physical or process control functions, such as opening or closing valves , measure proce...
