Digital Outputs (DO) in older Sensoft Vision

Applies to

Sensoft Vision 1.7.1 and before. For current software see this page.

Question

Can I get a digital output signal when a fault is detected? Or when an alarm is raised? Where would I connect the wires?

Answer

SenSystem Vision can output a voltage pulse when a defect is detected. It also outputs a voltage when a warning or an alarm is raised.

Software settings

To enable a digital outputs (DO) pulse for every defect, go to page Settings, click on Show advanced settings and then click on Every defect in the Defect marking or cutting group.

To make the change permanent save the settings.

Note that for precise defect marking or cutting, the pulse can be synchronized to the time when the defect passes a marking machine or the cutter.

To enable a digital output when a warning or an alarm is raised, you just have to write warning resp. alarm criteria. These criteria can be written in the Criteria field on the Main page. If it is not visible, please click with the right mouse button on the Threshold [µm] field and select Use Advanced Criteria from the context menu.

Hardware connection

The signal comes out of connector DO (ICD-50). The connector DO is galvanically separated from the rest of the electronics so that no noise is transmitted to the sensitive electronics. This means that the 24 V voltage for connector DO has to be supplied by an external power supply. The external 24 V power supply can be a switching power supply and should be connected to connector A1 on the rear panel of the Network controller (see the specifications for the A1 connector). The Output configuration is by default Emitter-Follower. The load should be greater than 300 Ohm, and the drawn current should not exceed 80 mA.
