摘要

A method for optimizing memory utilization in a gateway (304) of a process control and automation system is provided. The method includes obtaining (502), for a selected intelligent electronic device (IED) (302a-302c, 302a-302i), a configured IED description (CID) file (204) associated with the selected IED. The CID file is filtered (508) to generate a filtered CID file (208), The filtered CID file is provided (612) to the gateway, which is configured to use the filtered CID file to communicate with the selected IED.
