5.2 Trigger and Strobe

5.2.9

A/B Trigger for Incremental Encoder

An incremental encoder with A/B outputs can be used to synchronize the camera triggers to
the speed of a conveyor belt. These A/B outputs can be directly connected to the camera and
appropriate triggers are generated inside the camera.

The A/B Trigger feature is is not available on all camera revisions, see Appendix
B for a list of available features.

In this setup, the output A is connected to the camera input ISO_INC0 (see also Section 6.5.4
and Section A.1) and the output B to ISO_INC1.

In the camera default settings the PLC is configured to connect the ISO_INC inputs to the A/B
camera inputs. This setting is listed in Section 7.9.3.

The following parameters control the A/B Trigger feature:

TriggerSource

Set TriggerSource to

ABTrigger

to enable this feature

ABMode

Determines how many triggers should be generated. Available modes: single,

double, quad (see description below)

ABTriggerDirection

Determines in which direction a trigger should be generated:

fwd

: only

forward movement generates a trigger;

bkwd

: only backward movement generates a

trigger;

fwdBkwd

: forward and backward movement generate a trigger.

ABTriggerDeBounce

Suppresses the generation of triggers when the A/B signal bounce.

ABTriggerDeBounce is ignored when

ABTriggerDirection

fwdbkwd

ABTriggerDivider

Specifies a division factor for the trigger pulses. Value 1 means that all

internal triggers should be applied to the camera, value 2 means that every second
internal trigger is applied to the camera.

EncoderPosition (read only)

Counter (signed integer) that corresponds to the position of

incremental encoder. The counter frequency depends on the ABMode. It counts up/down
pulses independent of the

ABTriggerDirection

. Writing to this property resets the counter

to 0.

A/B Mode

The property ABMode takes one of the following three values:

Single

A trigger is generated on every A/B sequence (see Fig. 5.16).

TriggerFwd

is the trigger

that would be applied if

ABTriggerDirection

fwd

TriggerBkwd

is the trigger that would be

applied if

ABTriggerDirection

bkwd

TriggerFwdBkwd

is the trigger that would be applied if

ABTriggerDirection

fwdBkwd

GrayCounter

is the Gray-encoded BA signal that is shown as an

aid to show direction of the A/B signals.

EncoderCounter

is the representation of the

current position of the conveyor belt. This value is available as a camera register.

Double

Two triggers are generated on every A/B sequence (see Fig. 5.17).

Quad

Four triggers are generated on every A/B sequence (see Fig. 5.18).
