Hikrobot_GetInputLevel


Header: ThirdPartySdk.h
Namespace: avl
Module: ThirdParty

Get input level information. When edge detection is on, the interface cannot be used to obtain the level.

Syntax

void avl::Hikrobot_GetInputLevel
(
	Hikrobot_State& ioState,
	atl::Optional<int> inDeviceID,
	avl::HikrobotPortNumber::Type inPortNumber,
	bool& outLevel
)

Parameters

Name Type Range Default Description
Input will be modified ioState Hikrobot_State& Object used to maintain state of the function.
Input value inDeviceID Optional<int> 1 - NIL Device identification number - COM port number.
Input value inPortNumber HikrobotPortNumber::Type Device port number reference.
Output value outLevel bool& Logic level information for the specified port.

Remarks

This filter allows to get the input level information of a specific port of the device. When edge detection is on, the interface cannot be used to obtain the level.

I/O device driver software

This filter is intended to cooperate with a device using its vendor SDK. To be able to connect to a device, it is required to install Hikrobot VC4000 SDK.

Add DLL path to system environment variable is required.

In some computer models, digital inputs and outputs may operate in reverse logic (true is low signal level). Please check your device.

Recommended Hikrobot VC4000 SDK version for Aurora Vision Studio usage is 1.2.0.

Device identification

inDeviceID field can be used to pick one of multiple I/Os connected to computer. DeviceID can be set to:

  • COM port number - the number of the COM port used to communicate with the I/O.
