A driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source. The driver handles all proprietary communications between the data source and KEPServerEX; KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve. All OPC client interfaces can connect to KEPServerEX without additional charge.
