A.2.2 Line Type

One of seven available Line Types is selected from the drop-down menu list. The available
types are described in Table A-5.

The available input types for each discrete input line on the various In-Sight device models
are summarized in Table A-6.

A.2.3 Signal Type

Select a signal type for the selected input line, which controls the sensitivity of the input line
to edge transitions.

•

Rising Edge: Changes the state of the input line on the leading edge of a pulse.

•

Falling Edge: Changes the state of the input line on the falling edge of a pulse.

TYPE

DESCRIPTION

User Data

General purpose input line; used to drive events in the spreadsheet or to set a value in the
spreadsheet via the ReadDiscrete function.

Event Trigger

Triggers an event. To update the spreadsheet, the spreadsheet must contain an Event struc-
ture with its Trigger parameter set to this discrete input Line number.

Job ID Number Provides one bit of a Job ID Number, which is loaded when the State of a different input line

with a Type of Job Load Switch is ON.
NOTE: This functionality is provided for backwards compatibility, but it is strongly recom-
mended to use the direct Camera trigger input line.

Online/Offline

Forces the In-Sight device Offline or Online. 0 = Offline, and 1 = Online.

Acquisition
Trigger

Triggers the In-Sight camera to acquire an image. Requires the AcquireImage function’s Trig-
ger parameter to be set to External, and that a signal line is physically connected to the trigger
input of the In-Sight camera.

Job Load
Switch

ON reads all of the Job ID Number lines and loads the specified job.

NOTE

In order to use the Job ID Number function, the job to be loaded must be saved with a
numerical prefix of 0 to 19. For example, “8sample.job”.
