Header: ThirdPartySdk.h
Namespace: avl

Gets the I/O command list's internal counter value at the current moment.

Syntax

void avl::Matrox_GetCounterReferenceValue
(
	Matrox_State& ioState,
	atl::Optional<const avl::MatroxSystemAndDeviceIdentifier&> inDeviceID,
	int inCommandList,
	atl::int64& outReferenceValue
)

Parameters

Name Type Range Default Description
Input will be modified
 ioState Matrox_State& Object used to maintain state of the function.
Input value
 inDeviceID Optional<const MatroxSystemAndDeviceIdentifier&> NIL Device identification.
Input value
 inCommandList int 1 - 2 I/O command list.
Output value
 outReferenceValue int64& Command list's internal counter value.

Remarks

I/O device driver software

This filter is intended to cooperate with a Matrox device using its vendor SDK. To be able to connect to the device, it is required to install Matrox MIL X SDK. Matrox industrial PCs usually come with a preinstalled runtime license.

Add DLL path to system environment variable may be required.

Recommended Matrox MIL X SDK version for Aurora Vision Studio usage is V22H1 (10.50.924).

Device identification

Device field can be used to specify the number (rank) of the target board of the specified system type. Device can be set to:

  • DEFAULT - Specifies the default board. The default board is set in the MILConfig utility.
  • DEVn - Specifies the device number (rank) of the board (where 0 <= n <=15).

System field can be used to specify the system type. System can be set to:

  • HOST - Specifies the default build-in system like IO in industrial PC.
  • CONCORD - Specifies the IO system from Concord framegrabber.

This filter allows to obtain the current value of an I/O command list's counter. This value can later be used to register events at precise moments of time in relation to that value.
