GlobalShutter2.1.2.1.

Pixel

Active Area (Photodiode)

Storage Area

Microlens

Global shutter means that all pixels of the sensor are reset and afterwards exposed for a specied interval (t

exposure

).

For each pixel an adjacent storage area exists. Once the exposure time elapsed, the information of a pixel is transferred immediately to its storage area and read out from there.

Due to the fact that photosensitive surface get's "lost" by the implementation of the storage area, the pixels mostly are equipped with microlenses, which focus the light to the pixels active area.

Currently exposed pixels (Frame

Rolling shutter means that – in contrast to the global shutter – not the whole sensor is exposed at once, but single portions successively. It is said the shutter "rolls" over the

sensor�

For Baumer EXG cameras with rolling shutter this means two pointers are "rolling" across the sensor:

First, the reset pointer deletes any information of former exposures stored within the ▪ pixels (Frame

(n-1)

). After that the pixels are empty and restart collecting information

from incoming light – the new exposure (Frame

(n)

) begins.

Once a predened interval – the exposure time t ▪

exposure

– is elapsed, the readout pointer rolls across the sensor and the information of the pixels is read out. For example: On Baumer EXG50, the pass of a pointer lasts approx. 72 msec ▪ (t

Full Frame

).

Due to technical issues of rolling shutter, a ash control depending on the exposure time does not make sense. Such cameras should be used in a continuously illuminated environment.

Timings2.2.

The image acquisition consists of two seperate, successively processed components.

Exposing the pixels on the photosensitive surface of the sensor is only the rst part of the image acquisition. After completion of the rst step, the pixels are read out.

Thereby the exposure time (t

exposure

) can be adjusted by the user, however, the time need-

ed for the readout (t

readout

) is given by the particular sensor and used image format.

Baumer cameras can be operated with two modes, the Free Running Mode and the Trigger Mode.

The cameras can be operated non-overlapped

*)

or overlapped. Depending on the mode

used, and the combination of exposure and readout time:

Non-overlappedOperation OverlappedOperation

Here the time intervals are long enough to process exposure and readout successively.

In this operation the exposure of a frame (n+1) takes place during the readout of frame (n).

Due to the differing CMOS sensor models installed to the Baumer EXG cameras, the operation modes are subdevided into the respective camera models.

2.2.1. FreeRunningMode

In the "Free Running" mode the camera records images permanently and sends them to the PC. In order to achieve an optimal (with regard to the adjusted exposure time t

exposure

and image format) the camera is operated overlapped.

In case of exposure times equal to / less than the readout time (t

exposure

≤ t

), the maximum frame rate is provided for the image format used. For longer exposure times the frame rate of the camera is reduced.

3. Software

3.1. Baumer-GAPI

Baumer-GAPI stands for Baumer “Generic Application Programming Interface”. With this API Baumer provides an interface for optimal integration and control of Baumer Gigabit Ethernet (GigE) and Baumer FireWire™ (IEEE1394) cameras.

This software interface allows changing to other camera models or interfaces. It also allows the simultaneous operation of Baumer cameras with Gigabit Ethernet and FireWire™ interfaces.

This GAPI supports both Windows

®

(XP and Vista) and Linux® (from Kernel 2.6.x) operating systems in 32 bit, as well as in 64 bit. It provides interfaces to several programming languages, such as C, C++ and the .NET™ Framework on Windows®, as well as Mono

on Linux® operating systems, which offers the use of other languages, such as e.g. C# or

VB.NET.

3.2. 3rdPartySoftware

Strict compliance with the Gen<I>Cam™ standard allows Baumer to offer the use of 3rd Party Software for operation with cameras of the EXG series.

You can nd a current listing of 3

Image4.1. Acquisition

4.1.1. ImageFormat

A digital camera usually delivers image data in at least one format - the native resolution of the sensor. Baumer cameras are able to provide several image formats (depending on the type of camera).

Compared with standard cameras, the image format on Baumer cameras not only includes resolution, but a set of predened parameter.

These parameters are:

▪ Resolution (horizontal and vertical dimensions in pixels) ▪ Binning Mode(see chapter 4.1.6)

4.1.2. PixelFormat

On Baumer digital cameras the pixel format depends on the selected image format.

Denitions4.1.2.1.

RAW: Raw data format. Here the data are stored without processing.

Bayer: Raw data format of color sensors.

Color lters are placed on these sensors in a checkerboard pattern, generally in a 50% green, 25% red and 25% blue array.

Mono: Monochrome. The color range of mono images consists of shades of a single

color. In general, shades of gray or black-and-white are synonyms for monochrome.

RGB: Color model, in which all detectable colors are dened by three coordinates,

Red, Green and Blue.

Red

Green

Blue

Black

White

The three coordinates are displayed within the buffer in the order R, G, B.

BGR: Here the color alignment mirrors RGB.

YUV: Color model, which is used in the PAL TV standard and in image compression.

In YUV, a high bandwidth luminance signal (Y: luma information) is transmitted together with two color difference signals with low bandwidth (U and V: chroma information). Thereby U represents the difference between blue and luminance (U = B - Y), V is the difference between red and luminance (V = R - Y). The third color, green, does not need to be transmitted, its value can be calculated from the other three values.

YUV 4:4:4 Here each of the three components has the same sample rate.

Therefore there is no subsampling here.

YUV 4:2:2 The chroma components are sampled at half the sample rate.

This reduces the necessary bandwidth to two-thirds (in relation to 4:4:4) and causes no, or low visual differences.

YUV 4:1:1 Here the chroma components are sampled at a quater of the

sample rate.This decreases the necessary bandwith by half (in relation to 4:4:4).

◄Figure9

◄Figure10

RBG color space displayed as color tube.

Pixel depth: In general, pixel depth denes the number of possible different values for

each color channel. Mostly this will be 8 bit, which means 28 different "colors".

For RGB or BGR these 8 bits per channel equal 24 bits overall.

Two bytes are needed for transmitting more than 8 bits per pixel - even if the second byte is not completely lled with data. In order to save bandwidth, the packed formats were introduced to Baumer EXG cameras. In this formats, the unused bits of one pixel are lled with data from the next pixel.

4.1.3. ExposureTime

On exposure of the sensor, the inclination of photons produces a charge separation on the semiconductors of the pixels. This results in a voltage difference, which is used for signal extraction.

Light

Photon

The signal strength is inuenced by the incoming amount of photons. It can be increased by increasing the exposure time (t

exposure

).

On Baumer EXG cameras, the exposure time can be set within the following ranges (step size 1μsec):

4.1.4. HighDynamicRange(HDR)

The term "HDR" envelops several techniques to increase the dynamic range of brightness (from the brightest spot to the darkest spot of an image) beyond the native dynamic range of the imaging sensor. On Baumer cameras HDR-Images are created from a bracketing of several recorded – so called "Low Dynamic Range" (LDR) – images.

Look-Up-Table4.1.5.

The Look-Up-Table (LUT) is employed on Baumer monochrome cameras. It contains 212 (4096) values for the available levels of gray. These values can be adjusted by the user.

In this example the LUT is used to overwrite levels of gray which are not of interest or in the case of overdrive.

4.1.6. GammaCorrection

With this feature, Baumer EXG cameras offer the possibility of compensating nonlinearity in the perception of light by the human eye.

For this correction, the corrected pixel intensity (Y') is calculated from the original intensity of the sensor's pixel (Y

original

) and correction factor γ using the following formula (in over-

simplied version):

Y' = Y

original



◄Figure15

Some models of the EXG series are equipped with the ability for automatic adjustment of the exposure time by means of targetsettings in respect of the intensity of the recorded images.

ness

On Baumer EXG cameras the correction factor γ is adjustable from 0.001 to 2.

The values of the calculated intensities are entered into the Look-Up-Table (see 4.1.4.). Thereby previously existing values within the LUT will be overwritten.

If the LUT feature is disabled on the software side, the gamma correction feature also is disabled.

4.1.7. PartialScan/AreaofInterest(AOI)

With the "Partial Scan" function it is possible to predene a so-called Area / Region of Interest (AOI / ROI). This ROI is an area of pixels of the sensor. On image acquisition, only the information of these pixels is sent to the PC. Therefore all the lines of the sensor need not be read out, which decreases the readout time (t

readout

). This increases the frame

rate.

This function is employed, when only a region of the eld of view is of interest. It is coupled to a reduction in resolution.

The ROI is specied by four values:

▪ Offset X - x-coordinate of the rst relevant pixel ▪ Offset Y - y-coordinate of the rst relevant pixel ▪ Size X - horizontal size of the ROI ▪ Size Y - vertical size of the ROI

End ROI

Binning4.1.8.

On digital cameras, you can nd several operations for progressing sensitivity. One of them is the so-called "Binning". Here, the charge carriers of neighboring pixels are aggregated. Thus, the progression is greatly increased by the amount of binned pixels. By using this operation, the progression in sensitivity is coupled to a reduction in resolution.

Baumer cameras support three types of Binning - vertical, horizontal and bidirectional.

In unidirectional binning, vertically or horizontally neighboring pixels are aggregated and reported to the software as one single "superpixel".

In bidirectional binning, a square of neighboring pixels is aggregated.

4.1.9. BrightnessCorrection(BinningCorrection)

The aggregation of charge carriers may cause an overload. To prevent this, binning correction was introduced. Here, three binning modes need to be considered separately:

Binninig Realization

1x2 1x2 binning is performed within the sensor, binning correction also takes

place here. A possible overload is prevented by halving the exposure time.

2x1 2x1 binning takes place within the FPGA of the camera. The binning cor-

rection is realized by aggregating the charge quantities, and then halving this sum.

2x2 2x2 binning is a combination of the above versions.

White balance

The color signals r (red), g (green) and b (blue) of the sensor are amplied in total and digitized within the camera module.

Within the Bayer processor, the raw signals r', g' and b' are amplied by using of independent factors for each color channel. Then the missing color values are interpolated, which results in new color values (r'', g'', b''). The luminance signal Y is also generated.

The next step is the color transformation. Here the previously generated color signals r'', g'' and b'' are converted to the chroma signals U and V, which conform to the standard. Afterwards theses signals are transformed into the desired output format. Thereby the following steps are processed simultaneously:

Transformation to color space RGB ▪ or YUV

▪ External color adjustment

Color ▪ adjustment as physical balance of the spectral sensitivities

In order to reduce the data rate of YUV signals, a subsampling of the chroma signals can be carried out. Here the following items can be customized to the desired output format:

Order of data output ▪ Subsampling of the chroma components to ▪ YUV 4:2:2 or YUV 4:1:1 Limitation of the data rate to 8 bits ▪

4.3. Color Adjustment–WhiteBalance

This feature is available on all color cameras of the Baumer EXG series and takes place within the Bayer processor.

White balance means independent adjustment of the three color channels, red, green and blue by employing of a correction factor for each channel.

4.4.2. Gain

In industrial environments motion blur is unacceptable. Due to this fact exposure times are limited. However, this causes low output signals from the camera and results in dark images. To solve this issue, the signals can be amplied by a user-dened gain factor within the camera. This gain factor is adjustable from 1 to 10.

Increasing the gain factor causes an increase of image noise.

Some models of the EXG series are equipped with the ability for automatic adjustment of the gain factor by means of target-settings in respect of the intensity of the recorded images.

4.5. PixelCorrection

Generalinformation4.5.1.

A certain probability for abnormal pixels - the so-called defect pixels - applies to the sensors of all manufacturers. The charge quantity on these pixels is not linear-dependent on the exposure time.

The occurrence of these defect pixels is unavoidable and intrinsic to the manufacturing and aging process of the sensors.

The operation of the camera is not affected by these pixels. They only appear as brighter (warm pixel) or darker (cold pixel) spot in the recorded image.

CorrectionAlgorithm4.5.2.

On monochrome cameras of the Baumer EXG series, the problem of defect pixels is solved as follows:

Possible defect pixels are identied during the production process of the camera. ▪ The coordinates of these pixels are stored in the factory settings of the camera (see ▪ 4�5�3� Defectpixellist). Once the sensor ▪ readout is completed, correction takes place:

Before any other processing, the values of the two neighboring pixels on the left and ▪ the right side of the defect pixel, will be read out Then the average value of these 4 pixels is determined ▪ Finally, the value of the defect pixel is substituted by the previously determined ▪ average value

4.5.3. Defectpixellist

As stated previously, this list is determined within the production process of Baumer cameras and stored in the factory settings (see 4.8.1.).

Additional hot or cold pixels can develop during the lifecycle of a camera. In this case Baumer offers the possibility of adding their coordinates to the defectpixellist. The user can determine the coordinates

of the affected pixels and add them to the list. Once the defect pixel list is stored in a user set (see 4.8.), pixel correction is executed for all coordinates on the defectpixellist.

4.6.4. Debouncer

The basic idea behind this feature was to seperate interfering signals (short peaks) from valid square wave signals, which can be important in industrial environments. Debouncing means that invalid signals are ltered out, and signals lasting longer than a user-dened testing time t

DebounceHigh

will be recognized, and routed to the camera to induce a trigger.

In order to detect the end of a valid signal and lter out possible jitters within the signal, a second testing time t

DebounceLow

was introduced. This timing is also adjustable by the user.

If the signal value falls to state low and does not rise within t

DebounceLow

, this is recognized

as end of the signal.

The debouncing times t

DebounceHigh

and t

DebounceLow

are adjustable from 0 to 5 msec in steps

of 1 μsec.

4.7. User Sets

Four user sets (0-3) are available for the Baumer cameras of the EXG series. User set 0 is the default set and contains the factory settings. User sets 1 to 3 are user-specic and can contain the following information:

Parameter Parameter

Binning Image Format

Brightness Correction Look-Up-Table

Defect Pixel Correction Message Channel

Defectpixellist Offset (Black Level)

Flash Settings Partial Scan

Gain Pixel Format

Flash Settings Trigger Settings

These user sets are stored within the camera and and cannot be saved outside the device.

By employing a so-called "user set default selector", one of the four possible user sets can be selected as default, which means, the camera starts up with these adjusted parameters.

4.8. FactorySettings

The factory settings are stored in "user set 0" which is the default user set. This is the only user set, that is not editable.

4.9. Timestamp

The timestamp is part of the GigE Vision® standard. It is 64 bits long and denoted in

Ticks*). Any image or event includes its corresponding timestamp.

At power on or reset, the timestamp starts running from zero.

This Gigabit Ethernet-specic information on the device is part of the Discovery-Acknowledge of the camera.

Included information:

▪ MAC address

Current IP conguration (persistent IP / ▪ DHCP / LLA) Current IP parameters ( ▪ IP address, subnet mask, gateway) Manufacturer's name ▪ Manufacturer-specic information ▪ Device version ▪ Serial number ▪ User-dened name (user programmable string) ▪

5.2. PacketSizeandMaximumTransmissionUnit(MTU)

Network packets can be of different sizes. The size depends on the network components employed. When using GigE Vision®- compliant devices, it is generally recommended to use larger packets. On the one hand the overhead per packet is smaller, on the other hand larger packets cause less CPU load.

The packet size of UDP packets can differ from 576 Bytes up to the MTU.

The MTU describes the maximal packet size which can be handled by all network components involved.

In principle modern network hardware supports a packet size of 1500 Byte, which is specied in the network standard. However, so-called "Jumboframes" are on the advance as Gigabit Ethernet continues to spread. "Jumboframes" merely characterizes a packet size exceeding 1500 Bytes.

Baumer EXG cameras can handle a MTU of up to 65535 Bytes.

5.3. InterPacketGap

To achieve optimal results in image transfer, several Ethernet-specic factors need to be considered when using Baumer EXG cameras.

Upon starting the image transfer of a camera, the data packets are transferred at maximum transfer speed (1 Gbit/sec). In accordance with the network standard, Baumer employs a minimal separation of 12 Bytes between two packets. This separation is called "inter packet gap" (IPG). In addition to the minimal IPG, the GigE Vision

®

standard stipu-

lates that the IPG be scalable (user-dened).

IPG:

The IPG is measured in ticks (described in chapter

5.2). An easy rule of thumb is: 1 Tick is equivalent to 4 Bytes of data. You should also not forget to add the various ethernet headers to your calculation.

28

Example1:MultiCameraOperation–MinimalIPG5.3.1.

Setting the IPG to minimum means every image is transfered at maximum speed. Even by using a frame rate of 1 fps this results in full load on the network. Such "bursts" can lead to an overload of several network components and a loss of packets. This can occur, especially when using several cameras.

In the case of two cameras sending images at the same time, this would theoretically occur at a transfer rate of 2 Gbits/sec. The switch has to buffer this data and transfer it at a speed of 1 Gbit/sec afterwards. Depending on the internal buffer of the switch, this operates without any problems up to n cameras (n ≥ 1). More cameras would lead to a loss of packets. These lost packets can however be saved by employing an appropriate resend mechanism, but this leads to additional load on the network components�

Example2:MultiCameraOperation–OptimalIPG5.3.2.

A better method is to increase the IPG to a size of

optimal IPG = packet size + 2 × minimal IPG

In this way both data packets can be transferred successively (zipper principle), and the switch does not need to buffer the packets�

Figure37►

Max.IPG:

On the Gigabit Ethernet the max. IPG and the data packet must not exceed 1 Gbit. Otherwise data packets can be lost.

29

5.4. IPConguration

5.4.1. PersistentIP

A persistent IP adress is assigned permanently. Its validity is unlimited.

Please ensure a valid combination of IP address and subnet mask.

IPrange: Subnetmask:

0.0.0.0 – 127.255.255.255 255�0�0�0

128.0.0.0 – 191.255.255.255 255�255�0�0

192.0.0.0 – 223.255.255.255 255�255�255�0

These combinations are not checked by Baumer-GAPI, Baumer-GAPI Viewer or camera on the y. This check is performed when restarting the camera, in case of an invalid IP - subnet combination the camera will start in LLA mode.

* This feature is disabled by default�

5.4.2. DHCP(DynamicHostCongurationProtocol)

The DHCP automates the assignment of network parameters such as IP addresses, subnet masks and gateways. This process takes up to 12 sec.

Once the device (client) is connected to a DHCP-enabled network, four steps are processed:

▪ DHCP Discovery

In order to nd a DHCP server, the client sends a so called DHCPDISCOVER broadcast to the network.

▪ DHCP Offer

After reception of this broadcast, the DHCP server will answer the request by a unicast, known as DHCPOFFER. This message contains several items of information, such as:

Information for the client

MAC address

offered IP address

Information on server

IP adress

subnet mask

duration of the lease

InternetProtocol:

On Baumer cameras IP v4 is employed.

▲Figure38

Connection pathway for Baumer Gigabit Ethernet cameras: The device connects step by step via the three described mechanisms.

DHCP:

Please pay attention to the DHCP Lease Time.

◄Figure39

DHCP Discovery (broadcast)

◄Figure40

DHCP offer (unicast)

30

▪ DHCP Request

Once the client has received this DHCPOFFER, the transaction needs to be conrmed. For this purpose the client sends a so called DHCPREQUEST broadcast to the network. This message contains the IP address of the offering DHCP server and informs all other possible DHCPservers that the client has obtained all the necessary information, and there is therefore no need to issue IP information to the client.

▪ DHCP Acknowledgement

Once the DHCP server obtains the DHCPREQUEST, a unicast containing all necessary information is sent to the client. This message is called DHCPACK. According to this information, the client will congure its IP parameters and the process is complete.

5.4.3. LLA

LLA (Link-Local Address) refers to a local IP range from 169.254.0.1 to 169.254.254.254 and is used for the automated assignment of an IP address to a device when no other method for IP assignment is available.

The IP address is determined by the host, using a pseudo-random number generator, which operates in the IP range mentioned above.

Once an address is chosen, this is sent together with an ARP (Address Resolution Protocol) query to the network to to check if it already exists. Depending on the response, the IP address will be assigned to the device (if not existing) or the process is repeated. This method may take some time - the GigE Vision

®

standard stipulates that establishing connection in the LLA should not take longer than 40 seconds, in the worst case it can take up to several minutes.

5.4.4. Force IP

*)

Inadvertent faulty operation may result in connection errors between the PC and the camera. In this case "Force IP" may be the last resort. The Force IP mechanism sends an IP address and a subnet mask to the MAC address of the camera. These settings are sent without verication and are adapted immediately by the client. They remain valid until the camera is de-energized.

*) In the GigE Vision® standard, this feature is dened as "Static IP".

Figure41►

DHCP Request (broadcast)

Figure42►

DHCP Acknowledgement (unicast)

DHCPLeaseTime:

The validity of DHCP IP addresses is limited by the lease time. When this time is elapsed, the IP conguration needs to be redone. This causes a connection abort.

LLA:

Please ensure operation of the PC within the same subnet as the camera.

31

5.5. Packet Resend

Due to the fact, that the GigE Vision® standard stipulates using a UDP - a stateless user datagram protocol - for data transfer, a mechanism for saving the "lost" data needs to be employed.

Here, a resend request is initiated if one or more packets are damaged during transfer and - due to an incorrect checksum - rejected afterwards.

On this topic one must distinguish between three cases:

Normal Case5.5.1.

In the case of unproblematic data transfer, all packets are transferred in their correct order from the camera to the PC. The probability of this happening is more then 99%�

Fault1:5.5.2. Lost PacketwithinData Stream

If one or more packets are lost within the data stream, this is detected by the fact, that packet number n is not followed by packet number (n+1). In this case the application sends a resend request (A). Following this request, the camera sends the next packet and then resends (B) the lost packet.

In our example packet no. 3 is lost. This fault is detected on packet no. 4, and the resend request triggered. Then the camera sends packet no. 5, followed by resending packet no. 3.

Fault2:5.5.3. Lost PacketattheEndoftheData Stream

In case of a fault at the end of the data stream, the application will wait for incoming packets for a predened time. When this time has elapsed, the resend request is triggered and the "lost" packets will be resent.

◄Figure43

Data stream without damaged or lost packets.

◄Figure44

Resending lost packets within the data stream.

32

In our example, packets from no. 3 to no. 5 are lost. This fault is detected after the predened time has elapsed and the resend request (A) is triggered. The camera then resends packets no. 3 to no. 5 (B) to complete the image transfer.

TerminationConditions5.5.4.

The resend mechanism will continue until:

all packets have reached the pc ▪ the maximum of resend repetitions is reached ▪ the resend timeout has occured or ▪ the camera returns an error. ▪

Figure45►

Resending of lost packets at the end of the data stream.

33

5.6. MessageChannel

The asynchronous message channel is described in the GigE Vision® standard and offers the possibility of event signaling. There is a timestamp (64 bits) for each announced event, which contains the accurate time the event occurred. Each event can be activated and deactivated separately.

5.7. ActionCommand/TriggeroverEthernet

The basic idea behind this feature was to achieve a simultaneous trigger for multiple cameras.

Therefore a broadcast ethernet packet was implemented. This packet can be used to induce a trigger as well as other actions.

Due to the fact that different network components feature different latencies and jitters, the trigger over the Ethernet is not as synchronous as a hardware trigger. Nevertheless, applications can deal with these jitters in switched networks, and therefore this is a comfortable method for synchronizing cameras with software additions.

The action command is sent as a broadcast. In addition it is possible to group cameras, so that not all attached cameras respond to a broadcast action command.

Such an action command contains:

a Device Key - for authorization of the action on this device ▪ an Action ID - for identication of the action signal ▪ a Group Key - for triggering actions on separated groups of devices ▪ a Group Mask - for extension of the range of separate device groups ▪

Example:TriggeringMultipleCameras5.7.1.

The gure below displays three cameras, which are triggered synchronously by a software application�

Another application of action command is that a secondary application or PC or one of the attached cameras can actuate the trigger.

6. Start-Stop-Behaviour

Start/Stop6.1. Acquisition(Camera)

Once the image acquisition is started, three steps are processed within the camera:

Determination of the current set of image parameters ▪

▪ Exposure of the sensor

Readout of the sensor. ▪

Afterwards a repetition of this process takes place until the camera is stopped.

Stopping the acquisition means that the process mentioned above is aborted. If the stop signal occurs within a readout, the current readout will be nished before stopping the camera. If the stop signal arrives within an exposure, this will be aborted.

SpecialCase:AsynchronousReset

The asynchronous reset represents a special case of stopping the current acquisition. Thereby exposure is aborted immediately. Thus the current image is not read out and the image is upcasted.

This feature was introduced to accelerate the changing of image parameters.

Start/Stop6.2. Interface

Without starting the interface, transmission of image data from the camera to the PC will not proceed. If the image acquisition is started befor the interface is activated, the recorded images are lost.

If the interface is stopped during a transmission, this is aborted immediately.

Pause/Resume6.3. Interface

Pausing while the interface is operational, results in an interim storage of the recorded images within the internal buffer of the camera.

After resuming the interface, the buffered image data will be transferred to the PC.

6.4. AcquisitionModes

In general, three acquisition modes are available for the cameras in the Baumer EXG

series�

FreeRunning6.4.1.

Free running means the camera records images continuously without external events.

6.4.2. Trigger

The basic idea behind the trigger mode is the synchronization of cameras with machine cycles. Trigger mode means that image recording is not continuous, but triggered by external events.

This feature is described in chapter 4.6. Process Interface.

AsynchronousReset:
