An I/O Driver is an E3 module that communicates with a certain device by using .dll files. These Drivers are developed either by Elipse Software or by third-parties using a DDK (Driver Development Kit), supplied by Elipse Software, using the C/C++ programming language. Each Driver implements a different family of devices or protocols, according to the type of device or communication protocol. New Drivers are constantly developed by Elipse Software.

To insert an I/O Driver in a project, right-click a project's name in Explorer mode and select the Insert - I/O Driver option. In Domain mode, right-click the Server objects - Drivers and OPC item, select the Insert I/O Driver In option, and then a project's name.
