System and method for accessing and configuring field devices in a process control system using distributed control components
First Claim
1. A method comprising:
- receiving from an operator a first request to configure or access a field device in a process control system;
instantiating a device manager and a communication manager associated with the field device in response to the first request, the device manager configured to define the field device'"'"'s configuration, the communication manager configured to define an interface for communicating with the field device;
generating a user interface for interacting with the field device for presentation to the operator, the user interface generated using the device manager;
obtaining a second request associated with the field device at the device manager using the user interface;
providing the second request to a first emulator, the first emulator emulating the communication manager;
providing the second request from the first emulator to a second emulator, the second emulator emulating the device manager; and
providing the second request from the second emulator to the communication manager, the communication manager configured to communicate the second request to the field device over a communication link using a specified protocol.

Abstract
A system includes a client and an interface component. The client includes (i) a device manager associated with a field device in a process control system and (ii) a first emulator configured to emulate a communication manager. The device manager defines a user interface associated with the field device. The interface component includes (i) a second emulator configured to emulate the device manager and (ii) the communication manager. The communication manager is configured to communicate with the field device over a communication link using a specified protocol. The client is physically separated from the interface component. The communication manager could represent a communication Device Type Manager (DTM), and the device manager could represent a device DTM. Also, the first emulator could emulate at least some functions of the communication DTM, and the second emulator could emulate at least some functions of the device DTM.
