What Is a Driver?

KEPServerEX is more than an OPC server—it's a connectivity platform for industrial automation and IoT. Simply download KEPServerEX, and then select from Kepware's library of more than 150 device drivers, client drivers, and advanced plug-ins to fit the communication requirements unique to your industrial control system.

A driver is a software component that enables KEPServerEX to meet the connectivity requirements of a specific device, system, or other data source. The driver handles all proprietary communications to the data source for KEPServerEX; the client interfaces handle all supported OPC, proprietary, and open standards connectivity to applications that monitor or control the devices.

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve.
