HALCON: Set IP Address
This topic introduces how to obtain and modify the camera’s current IP address, subnet mask, and gateway in Windows using the HALCON samples provided by Mech-Mind.
Obtain Sample and Select Camera
Before obtaining or modifying the IP address, you need to download the sample and set the camera to be connected in the sample.
-
Open the sample in HDevelop: Open HDevelop, and drag the sample into HDevelop.
-
Select the line containing the info_framegrabber operator in Program Windows, and click
in the toolbar or press the F6 key to run this line. -
In the Control Variables area, double-click DeviceInfos to display a list of all the available cameras.
-
In the list, double-click the camera that you want to connect, and copy the camera name after unique_name: or user_name:.
user_name is the custom camera name. You can customize the camera name in Mech-Eye Viewer. -
Locate the following line, and replace MechEye with the copied unique_name or user_name.
DeviceInfo := 'MechEye'
Obtain Camera IP Address, Subnet Mask and Gateway
Please follow these steps to obtain the current IP address, subnet mask and gateway of the camera:
Run the sample by clicking 
in the toolbar or pressing the F5 key. In the Control Variables area, check the following variables for the current IP address, subnet mask and gateway of the camera.
-
CurrentIPAddressString: IP address
-
CurrentSubnetMaskString: subnet mask
-
CurrentDefaultGatewayString: gateway
|
If the camera firmware version is 2.0.2 or below, the above information cannot be obtained, and the error message will be recorded in the Exception variable. |
Set Static IP address
This sample sets a static IP address by default. Please follow these steps to modify the IP address, subnet mask and gateway of the camera:
-
Click
in the toolbar to reset program execution. -
Locate the following line, and change the IP address, subnet mask and gateway to the values to be set:
IPAddressString := '192.168.1.100' SubnetMaskString := '255.255.255.0' DefaultGatewayString := '192.168.1.1' -
Run the sample by clicking
in the toolbar or pressing the F5 key. -
Restart the camera to make the new settings take effect.
Set Dynamic IP Address
Please follow these steps to dynamically assign an IP address to the camera:
-
Click
in the toolbar to reset program execution. -
Locate the following line, and replace true with false.
set_framegrabber_param (AcqHandle, 'GevCurrentIPConfigurationPersistentIP', true) -
Run the sample by clicking
in the toolbar or pressing the F5 key. -
Restart the camera to make the new settings take effect.
