A process often needs to be configured as a series of steps. A collection of steps for a complete process is sometimes called a “recipe”. The example below shows:
- The recipe displayed as a table
- Buttons for inserting, editing and deleting steps (the insert and edit buttons cause a subscreen to pop up, where the step is defined)
- Display of recipe “faults”, if any. The faults box is coloured red if there is a fault and saving of the recipe is not permitted until the fault is rectified. A fault could, for example be the setting of a temperature and pressure that are not allowed simultaneously.
- Display of key physical parameters in a chart. As the recipe is altered, the chart automatically updates.
