Assembly Line
Previous pageReturn to chapter overviewNext page

Marking On The Fly can be used to set up an assembly line production with many targets passing by each after another through the scanner field.

If there is no external trigger signal for each part, but only for the first one and if the distance between the parts is always the same, the assembly line can be realized by the following solution (discriminate between USC and RTC cards).

For USC-1/-2/-3 and RTC5/6 cards, the Trigger Control Objects can be used together with the Mark Loop Count. In this case, set up the job as wished for one marking including all the trigger control objects. Then, select those objects in the entity list and group them all together with Edit → Group. Finally, set the Mark Loop Count of this group to -1 in the Entity Info property sheet.

For RTC-3/-4, the trigger control objects are not available. Looping is possible with the Simulate Ext Start feature.

For RTC5/6 cards, the looping can alternatively be done with the Simulate Ext Start feature.

note

You need an encoder for the RTC cards as well as for the USC-1 card. The simulation mode can not be used for this. Only the USC-2 and USC-3 card can handle the simulation mode together with the ScWaitForTrigger and ScMotfOffset objects.
