System requirements ibaPDA-Interface-LMI-Gocator
2 System requirements
The following system requirements are necessary for the use of the LMI-Gocator data interface:
■ ibaPDA v8.0.0 or more recent
■ License for ibaPDA-Interface-LMI-Gocator (supports up to 2 sensors, i.e. 2 connecons)
■ If you need more than 2 connecons, you will require addional one-step-up-Interface-LMI-
Gocator licenses for each addional 2 connecons. The total limit is 16 connecons.
Also Gocator sensors used in a buddy mode setup require a license.
A minimum rmware version "Gocator Release 4.6 SR1" (v4.6.7.17) is required. Sensors of older
series available only with rmware versions < v4.6 are not supported (e.g. Gocator 1100, 2000
series).
For further requirements for the used computer hardware and the supported operang sys-
tems, please refer to the ibaPDA documentaon.
Note
The 2D top view is parcularly suitable for displaying the measured values. This
display is possible with live data but only with the trend graph and HD trend
graph objects of the ibaQPanel soware. Therefore it is recommended to pur-
chase addional licenses for ibaQPanel and/or ibaHD server.
In the oine analysis with ibaAnalyzer, the 2D top view is included as standard.

3.1 Generalinformaon
The LMI-Gocator interface can be used to measure prole data from Gocator® sensors (LMI
Technologies Inc.). Data from several, adjacent sensors can be collected and merged into a sin-
gle prole.
3.2 System topologies
The connecons between the devices and ibaPDA can be established via the computer's stan-
dard Ethernet ports.
No further soware is necessary for operaon.
Note
It is recommended carrying out the TCP/IP communicaon on a separate net-
work segment to exclude a mutual inuence by other network components.
3.3 ConguraonandengineeringibaPDA
The engineering for ibaPDA is described in the following. If all system requirements are fullled,
ibaPDA displays the LMI-Gocator interface in the interface tree of the I/O Manager.
3.3.1 Interfacesengs
The interface itself has the following funcons and conguraon opons:
Setallvaluestozerowhentheconnecontoadeviceislost
If enabled, all measured values of the device are set to zero as soon as the connecon is lost. If
this opon is disabled, ibaPDA will keep the last valid measured data in memory at the me the
connecon was lost.
Startacquisionevenifadeviceisnotaccessible
If this opon is enabled, the acquision will start even if the device is not accessible. In case of
an error, a warning is indicated in the validaon dialog. If the system has been started without a
connecon to the device, ibaPDA will periodically try to connect the device.

Connecontable
The table shows the cycle mes and error counters for the individual connecons during data
measurement. Each table row corresponds to a congured Gocator module. To reset the calcu-
lated mes and error counters, simply click on the <Reset counters> buon. See ì Connecon
table, page 20
Openlogle
Messages related to the LMI-Gocator interface are wrien in a separate log le. To open the
current log le click <Open log le>.
<Resetstascs>
Click this buon to reset the calculated mes and error counters in the table to 0.
3.3.2 Adding a module
1. Click on the blue command Click to add module… located under each data interface in the
Inputs or Outputs tab.
2. Select the desired module type in the dialog box and assign a name via the input eld if re-
quired.
3. Conrm the selecon with <OK>.
One Gocator module corresponds to a full prole, which is typically, but not necessarily, the
composion of the proles of several adjacent Gocator sensors.

3.3.3 Generalmodulesengs
In the General tab the following module sengs can be congured:
Basicsengs
ModuleType(informaononly)
Indicates the type of the current module.
Locked
You can lock a module to avoid unintenonal or unauthorized changing of the module sengs.
Enabled
Enable the module to record signals.
Name
You can enter a name for the module here.
Module No.
This internal reference number of the module determines the order of the modules in the signal
tree of ibaPDA client and ibaAnalyzer.
Timebase
All signals of the module are sampled on this mebase.
Usemodulenameasprex
This opon puts the module name in front of the signal names.
Gocatorsengs
One Gocator module corresponds to a full prole which is typically (but not necessarily) the
composion of the proles of several, adjacent Gocator sensors. Apart from the standard op-
ons, the following specic sengs can be congured:
10 2.0
LMI-Gocator interface ibaPDA-Interface-LMI-Gocator
Sampleme
This determines how fast prole data is generated by the Gocator sensors. Although in theory, it
is possible to set the sample me as low as 1 ms, in pracce it might be limited by the sensors.
Resoluon
This determines the distance in microns between two neighbouring prole samples. Allowed
values are 100 µm, 200 µm, 250 µm, 500 µm and 1000 µm. When changing the resoluon,
ibaPDA will automacally adjust the number of analog signals.
Sensor width
The sensor width determines the width of the measured prole on the X-axis (as dened in the
Gocator documentaon) of one Gocator sensor. This implies that the prole width is the same
for all Gocator sensors in the module. When using Gocator sensors in buddy mode, the master
sensor acts as one relavely wide virtual sensor; the sensor width then corresponds to the total
prole width of all Gocator sensors combined.
Maximumdatadelay
Maximum allowed dierence (in ms) between the requested mestamp and the actual me-
stamp of the (reconstructed) prole.
Change this parameter only aer consulng the iba support.
Datameout
The number of sample mes ibaPDA can wait without receiving a new (reconstructed) prole.
Change this parameter only aer consulng the iba support.
Read-only
When enabled, ibaPDA will not change any sengs in the Gocator sensors. This must be en-
abled when using Gocator sensors in a buddy conguraon.

ibaPDA-Interface-LMI-Gocator LMI-Gocator interface
3.3.4 Conguraonofsensors
In the Connecon tab you can congure the sensors associated with a module.
Sensors can be added and removed manually by using the buon and buon respecve-
ly. In addion the discovery funconality ( ) will list all available sensors in the network. Dis-
covered sensors which are not necessary for the conguraon can be removed from the table.
For sensors in a buddy mode group the master of the group is discovered and listed.
For each sensor, the following sengs can be congured:
Name
This is an idener used internally in ibaPDA and is not related to any seng in the sensor. The
default value when discovering a new sensor is the serial number.
IPAddress
The IP address at which a sensor can be reached for communicaon. By using the buon,
the web interface of the sensor can be opened (standard web browser).
Xoset
The oset of a sensor in mm along the axis of the sensor's laser line. The "X oset" value is
retrieved from and stored in the sensor (if the read-only module property is disabled). This pa-
rameter is required when construcng a prole based on the data of mulple sensors. It can be
measured manually or using ibaPDA when acquiring a test prole of all sensors (see below).
12 2.0
LMI-Gocator interface ibaPDA-Interface-LMI-Gocator
Note
The "X oset" value must be a mulple of the Gocator module's resoluon. For
example, if the resoluon is set to 500 µm, a value of 10.486 mm will be auto-
macally set to 10.500 mm.
Zoset
The oset of a sensor in the height direcon. This value is retrieved from and stored in the sen-
sor (if the read-only module property is disabled). Typically this parameter is obtained by using
the alignment funcon of the sensor (see below).
Angle
The angle between the object to be measured and the sensor plane. This value is retrieved from
and stored in the sensor (if the read-only module property is disabled). Typically this parameter
is obtained by using the alignment funcon of the sensor (see below).
Bank
This is the number of a bank, the sensor is assigned to. A bank is a subgroup of sensors that can
generate the laser line and measure the prole simultaneously without interfering with each
other. The following gure illustrates an array of 6 sensors measuring a slab:
In the ideal case when the sensors can be posioned precisely next to one another, there will be
no overlap of laser lines. However for high features in the slab, the projected width of the laser
line of the sensor is smaller than for low features. Thus if an enre slab with relavely high and
low features should be covered, the sensors must be posioned with some overlap between the
laser lines.
2.0 13
ibaPDA-Interface-LMI-Gocator LMI-Gocator interface
In case all sensors would be generang the laser line and measuring the prole at the same
me, the laser line from sensor 1 would interfere with the one from sensor 0 and would aect
the measurement data. Note that sensor 1 would also interfere with sensor 2. To prevent this
unwanted behavior, it is possible to me mulplex the exposure.
Example:
Assuming you would like to obtain a full prole every millisecond (i.e. you can divide a conn-
uous measurement in me slots of 1 ms) and the exposure me (i.e. the me required to get
a good measurement of the prole) of one sensor is 400 µs. In each me slot, sensor 0 could
generate the laser line and measure the prole from 0 µs to 400 µs and sensor 1 could do so
from 400 µs to 800 µs, thus sll leaving a margin of 200 µs. There is no longer any interference,
since the sensors that normally overlap now generate their laser lines at dierent points in me.
Since sensor 1 and sensor 2 also overlap, they should also me mulplex the exposure. Howev-
er, since sensor 0 and sensor 2 do not overlap, they can generate the laser line simultaneously.
In the gure above this implies that sensor 0, 2 and 4 can generate the laser line at the same
me (e.g. in the subslot from 0 µs to 400 µs) and 1, 3 and 5 can generate the laser line at anoth-
er me (e.g. in the subslot from 400 µs to 800 µs). Sensors 0, 2 and 4 form the rst bank; sen-
sors 1, 3 and 5 constute the second bank.
Since the Gocator sensors operate independently and are unaware of each other, this seng is
not saved in the sensor.
Exposureme
The required me in microseconds to generate a valid prole for this sensor. This value is re-
trieved from and stored in the sensor (if the read-only module property is disabled). Typically it
is obtained by conguring the sensor in its web interface (by checking the live image).
Aligned
A read-only eld that indicates whether the sensor has been successfully aligned. This eld is
updated when a sensor is automacally added using the discovery funcon or every me a con-
necon test is done.
Checkingasensor'sstatusandconnecon
To check whether a connecon to a sensor can be created or to obtain some basic diagnosc
informaon, select the sensor in queson and click the buon to test the connecon to the
sensor. You may click on the buon to test the connecon to all listed sensors.
Select the Status tab below the list. Tesng the connecon will display the current status, mod-
el, rmware version and serial number of the sensor and, if applicable, the status informaon of
its buddy sensors.
Aligningasensor(notavailableinread-onlymode)
Before using the sensors in a measurement the "Z oset" and "Angle" need to be congured
properly. To do so, place a at surface below the sensors (i.e. where the measurement object
will eventually be placed) and click the buon to align the selected sensor or the buon
to align all sensors. The "Z oset" and "Angle" will be updated automacally.
14 2.0
LMI-Gocator interface ibaPDA-Interface-LMI-Gocator
Acquiringasingleprole
Though the "X oset" will also be set by aligning the sensors, this will not be the correct value:
the "X oset" is the distance of one sensor to another reference sensor. Since sensors are un-
aware of each other, there is no way to determine this automacally. However the following
method can make it easier to get a relavely precise value for this "X oset": by clicking the
buon (for a single sensor or sensors in buddy mode ) or the buon (for all sensors), the
current prole is retrieved and displayed in the Alignment tab.
In the graph above, the prole for two aligned sensors is displayed; the "X oset" however is
not yet set correctly. Since the sensors overlap, part of their proles should match. In this ex-
ample, the red circled region should overlap with the blue circled region. Using markers in the
graph you can measure the distance between these two regions and use those value as the "X
oset" of one of the sensors. When you enter this value in the sensor table and acquire the pro-
les again, you get the following result:
Now the proles overlap as they should and apparently the correct value for the "X oset" has
been found.
2.0 15
ibaPDA-Interface-LMI-Gocator LMI-Gocator interface
Note
Markers can be made visible by exing the live mode. You have the following op-
ons to exit live mode:
1. Right click on the graph (context menu) - select Live mode or
2. Zoom into graphic or
3. Press <F6>
To return to live mode press <F6> again or use the context menu.
Once the "X oset" has been adjusted, the number of signals needs to be updated. This can be
done by clicking the buon. Based on the module's resoluon and "X oset" parameters of
all sensors, ibaPDA will generate the required number of signals with each signal corresponding
to a single data point of the enre prole.
3.3.5 "Analog" tab
In the Analog tab, no further changes need to be made (apart from changing the signal names
"Gain" and "Oset", if desired).
3.3.6 Vector signal
For each LMI-Gocator module ibaPDA generates automacally a vector signal with the mea-
sured line data. The vector signal can be found in the "Groups" secon of the I/O Manager.
The name consists of the module name, module number and the sux “prole”.
Tip
The vector signal can be used directly in the 2D color-coded display of the sur-
face prole in ibaQPanel and/or ibaAnalyzer.

LMI-Gocator interface ibaPDA-Interface-LMI-Gocator
3.3.7 Buddy mode
In case the rmware of the Gocator sensors allows for it, it is advised to congure mulple Go-
cator sensors in buddy mode and to set all relevant parameters using their web interface. In
ibaPDA it is then only required to congure the general module sengs (note that read-only
mode must be enabled) and adding one sensor (i.e. the main sensor of the buddy group) with
its IP address (other sengs like X and Z oset are not relevant). Only the main sensor is discov-
ered and accessible when using mulple Gocator sensors in buddy mode (see the gure below):
When doing a connecon test the status informaon of the main sensor will be displayed in the
Status tab along with some basic informaon concerning its congured buddies.
The total prole width (i.e. the prole width of all buddy sensors combined) is also displayed
and can be used to congure the Sensor width property in the General tab of the module.
In the Alignment tab you can see the measured values of all sensors belonging to the buddy
group and check their alignment.
2.0 17
ibaPDA-Interface-LMI-Gocator LMI-Gocator interface
When read-only mode has not been enabled in the Gocator module and you try to acquire a
prole or align the sensors, an error will appear in ibaPDA indicang that buddy sensors can
only be used when read-only mode is enabled.
