Appendix A - Configuring Discrete Outputs
24
The Discrete Output Settings dialog shows three configurable line parameters: Name, Type
and Details.
A.1.1 Line Name
Assign a new name for an output line by selecting the default name and typing a new name.
The name may be up to 15 characters. The Line Name is used for reference purposes only;
it does not change the functionality of the output line and cannot be referenced in the
spreadsheet.
A.1.2 Line Type
Available Line Types are selected from the Type drop-down list.
Table A-2: Discrete Output Line Types
Type Description
Programmed Enables a WriteDiscrete function in the spreadsheet to control the state of
this output line. Either pulsed or steady-state.
High Forces the output to HIGH (1).
Low Forces the output to LOW (0).
Acquisition Start Signals that the In-Sight sensor has initiated an acquisition. Always
pulsed.
Acquisition End Signals the completion of sensor acquisition. Always pulsed.
Job Completed Signals each time the spreadsheet has completed an update. Always
pulsed.
System Busy HIGH when the In-Sight sensor is running a job or responding to user
input, LOW when the In-Sight sensor is idle.
Job Load OK Signals the successful loading of a job. Always pulsed.
Job Load Fail Signals the failure of a job load. Always pulsed.
ERR: Missed Acquisition Signals that an acquisition trigger was received before an Acquisition End
signal was sent, or that no image buffer was available for image
acquisition when an acquisition trigger was received. Always pulsed.
The Trigger parameter in the AcquireImage property sheet must be set to
Camera to use the ERR: Missed Acquisition output.
ERR: Tracking Overrun Signals that the spreadsheet issued a delayed discrete output signal
sometime after the time it was expected. Always pulsed.
ERR: Tracking Queue Full Signals that the spreadsheet issued a delayed discrete output for a line
where a different output had been previously scheduled to occur at the
same time. Always pulsed.
Online/Offline HIGH when In-Sight is Online, LOW when In-Sight is Offline.
