Abstract

This article describes the patch mechanism using NVM (Non-Volatile Memory). There are some display terminals called DFTs (Distributed Function Terminals) whose objects are stored in the controller's diskette and are down loaded into the memory of the device when it is powered on. And, these devices can have the patch data in the controller's diskette. (Image Omitted) This article shows how to control the patch data for a DCA (Device Cluster Adapter) terminal which has NVM on it but cannot have its object in the controller's diskette. This patch mechanism uses the patch data transaction function between the device and the controller.
