7... HYPERNET™ I CON BASED PROGRAMMING
A simple application of the Enable input might be in an engine temperature recording application. A Thermocouple icon may be enabled / disabled by a Logic signal that is True when the engine ignition is ON. With this configuration, temperature recording will only occur when the engine is running.
The Enable input can also be used for optimizing the speed of Program Nets and/or minimizing the amount of data collected as the processing normally done by an icon in a Program Net is not performed if the Enable input is False. For example, a Program Net may be built that has several input temperatures that are scanned on a fairly high speed basis. By use of the Enable terminal, the data flow to OMP- MODL memory may be disabled during normal operating conditions and enabled when abnormal temperature readings are detected.
UPDATE INPUT TERMINAL
The Input signal icons (Thermocouple, VDC, GPDI, etc) are all equipped with an Update input terminal located in the center top of the graphic. Whenever this Update terminal receives an Update command, it proceeds to update its output terminal value (assuming that its Enable terminal is True or not connected).

Configuring Icons
Most of the icons within HyperWare must be configured before they can be used. User configuration entails selection of various icon operational parameters such as names, input ranges, sampling rates, etc and is simply done through dialog boxes associated with each icon.
