Is it feasible for interfaces and operational procedures to have a common look and feel?
All host systems support a number of basic functions, such as reading, writing, printing, numerical comparisons, and data storage. The lab found in all cases users could call up certain functionalities, such as device status transmittals or processing parameter displays, from the same locations. Since those basic functions are not constituents of EDDs, they appear on the respective host systems in forms that have a common look and feel. However, device operational procedures or parameter terminologies, which are usually implemented in EDDs, differed from manufacturer to manufacturer in this test program. Text entries and tabular data previously dominated visual displays of EDDs. It is now possible to implement much more sophisticated interfaces, although they may differ widely from manufacturer to manufacturer. It is imperative to develop a guideline to implement EDDs for typical types of devices from all manufacturers, particularly during early implementation of the standard. That gui
