ibaCapture is an image acquisition and recording system integrated in the ibaPDA data acquisition system. It facilitates video recording synchronized to measurement value acquisition. The synchronized combination of image data and measured data allows relationships between the process and the measurements to be easily recognized and communicated.

Description

The ibaCapture interface is displayed by default in the I/O Manager. However, it can only be used in conjunction with an ibaCapture or ibaVision server. 1

There is only one ibaCapture interface per ibaPDA system. You can add up to 64 subordinate ibaCapture and/or ibaVision modules to this interface. Each module is assigned to one ibaCapture or ibaVision process.

The interface provides an overview of all active ibaCapture server connections.

A TCP/IP connection is required between the ibaPDA server and the ibaCapture server.

The ibaCapture interface also provides output modules. With these output modules, it is possible to control the camera recording and, with PTZ cameras, to control the cameras.

For more information see Outputs.

Interface configuration

Port no.

The port number is specified in the entry field in the top left. The port number is used to receive synchronization data from one or more ibaCapture servers via a TCP/IP connection. The default port number, 9121, can generally be used.

If the default port number is already used in your network for other purposes, you can change it here. The port number is always transmitted to the ibaCapture server to inform the video server about the correct port number for exchanging the synchronization messages.

<Reset port to default>

The port number 9121 is set.

<Allow port through firewall>

When installing ibaPDA, the default port numbers of the protocols used are automatically entered in the firewall. If the port number is changed here or the interface has subsequently been activated, it is necessary to allow this port through firewall.

Network interfaces

Using this drop-down list, you can select which network adapters on your computer are used for this interface. The sockets will be opened for communication only on the selected network adapters. In case a network adapter has multiple IP addresses configured, a socket will be opened for all of these IP addresses. At least one network adapter should be selected to get the interface configuration validated. If you select None, an error message will be displayed when validating the I/O configuration. By default, the option All is selected.

ibaCapture interface licenses

The available ibaCapture licenses are shown in the top right of the screen. You need one license for each connection to an ibaCapture server.

Start acquisition even if an ibaCapture server/ibaVision process/ibaCapture-ScreenCAM host is not accessible

If you want to make sure that the measurement starts regardless of whether an ibaCapture server is accessible or not, you should check this option.

Restart acquisition when the configuration of an ibaCapture server has changed

If you select this option, the acquisition of ibaPDA automatically starts after a configuration change on the ibaCapture server and the changed settings on the ibaCapture server take effect immediately.

Rename camera signals with XML file

If there is the possibility or requirement that the system configuration of one or more ibaCapture server(s) will be changed from time to time, e.g., due to the renaming of cameras, then the XML file is a helpful tool.

If this option is selected, then ibaPDA reads the XML file which is specified in the "Rename file" field. If necessary, you have to enter the username and password if the XML file is stored on a network drive.

With the <Show example> button you can open a sample file in the standard text editor of the computer (e.g., Notepad), where you can see the correct syntax.

TCP Port / UDP Port

"OK" is displayed here if the socket can be opened on this port. "ERROR" is displayed if conflicts occur, e.g., if the port is already busy.

Messages received with invalid length/ID

These counter values should ideally always be 0 (zero). If the values rise, this indicates errors in the synchronization between the ibaPDA server and the ibaCapture server.
Connection table

The table contains diagnostic information about the current connections to the ibaCapture servers and ibaVision processes. One row is created in the table for each connection.
Available modules

  • ibaCapture (input and output module)

  • ibaVision input (input module)

  • ibaVision output (output module)

Also see Module types ibaCapture and ibaVision for a brief description of the modules.
