Memory Based Driver OPC Server - KEPServerEX OPC Servers

Overview

The Memory Based Device Driver is designed specifically for use with our 32 bit OPC Server KEPServerEX.

The Memory Based Device Driver enables you to retain tag values between server runs. When the driver's Item Persistence is activated, all D register addresses and string values will be saved when the OPC server shuts down. The values are restored the next time you open the OPC server project.

This driver is part of the Simulation Suite. Purchasing either the Advanced Simulator Driver or the Memory Based Driver entitles you to both drivers.
