A large number of devices offer a similar kind of capabilities. For example, data acquisition all offer sampling at some rate. If each such device were to have a different interface, engineers using them would need to be familiar with each device specifically, inhibiting transfer of know-how from working with one device to another and increasing the chance of engineering errors due to a miscomprehension or incorrect assumptions. In the Nominal Device Model (NDM) model, we propose to standardize the EPICS interface of the analog and digital input and output devices, and image acquisition devices. The model describes an input/output device which can have digital or analog channels, where channels can be configured for output or input. Channels can be organized in groups that have common parameters. NDM is implemented as EPICS Nominal Device Support library (NDS). It provides a C++ interface to developers of device-specific drivers. NDS itself inherits well-known asynPortDriver. NDS hides from the developer all the complexity of the communication with asynDriver and allows to focus on the business logic of the device itself.
