Machine Vision - Control, Configuration management, recipe management, result management

11.4.1.1 Overview

VisionEvents are generated to signal noteworthy events during the operation of the vision system which do not require interaction.

All non-inherited properties are optional and stay optional on the concrete sub-types because these EventTypes will be used under very different operational circumstances in the vision system; it is therefore not possible to specify that, e.g. a jobId shall be mandatory, since an event may be triggered during the preparation of a recipe, when no job is running.

However, the intention is for the server to provide as much information to the client as possible, i.e. fill as many properties as possible.

The EventType for VisionEvents is formally defined in Table 129.
