Methods and apparatus to reduce memory requirements for process control system software applications

摘要

Methods and apparatus to reduce memory requirements of software applications in a process control system are disclosed. An example apparatus includes a primary process space to execute a primary application for use in a process control system, a primary user interface associated with the primary application and to be rendered on a display, and a secondary application to be invoked via the primary application. The secondary application includes a client application to enable interaction between the primary application and the secondary application, and a server application that serves the client application to implement at least one software component to generate a secondary user interface associated with the secondary application. The secondary user interface is to be communicated to the primary application to be rendered within the primary user interface.

1. An apparatus, comprising:
a processor to execute a primary application within a primary address space, the primary application for use in a process control system; a display to render a primary user interface associated with the primary application; and a secondary application to be invoked via the primary application, the secondary application corresponding to a Device Type Manager associated with a type of field device in the process control system, the secondary application comprising a client portion and a server portion, a single instance of the server portion to serve separate first and second instances of the client portion with information for a secondary user interface associated with the secondary application to be rendered within the primary user interface, the information generated by the server portion implementing at least one software component for each of the first and second instances of the client portion, the primary application to provide to each of the first and second instances of the client portion respective first and second pointers pointing to the primary application, the first and second instances of the client portion to share the respective first and second pointers with the server portion, the first and second instances of the client portion to pass-through the information from the server portion to the primary application via the respective first and second pointers.
