sometimes it is necessary to hide certain recipegroups (e.g. with factory settings) from the normal user in the runtime. This used to be possible only by removing the recipegroup selection window, losing some operation comfort.

With equipment modelling, this can be achieved elegantly. E.g. the recipegroup for factory settings recipe group can be assigned a specific equipment model, which is not included in the filter, or no equipment model at all, making it also unavailable when a filter is set to a certain equipment model to which the standard recipe groups belong.

The filter button could be protected with a password, here the factory settings recipegroup can be linked to a "visible" equipment model. Alternatively, a password protected button could be used to open the special equipment model, which includes this recipe group.
