2.3 General safety instructions

n

Installation, mounting and adjustment of this product may only be executed by skilled

and authorised personnel.

n

Only use the provided mounting devices and accessories for product installation.

n

Unused outputs must not be assigned. Unused strands must be isolated.

n

Do not exceed the maximum permissible bending radius of the cable.

n

Prior to electrical connection of the product, the system must be down and not live.

n

Where mandatory, use shielded cables for protection against electromagnetic interfer-

ence.

n

Where plug-in connections are added to shielded cables by the customer, these plug-in

connections must be EMC compliant and the cable shield must be attached to the con-

nector housing over a large surface area.

n

For laser safety reasons, the power supply of this sensor must be switched off when the

entire plant or machine is switched off.

CAUTION

The sensor has laser class 2.

Never direct the laser at an eye. It is recommended not to direct the beam into empty space

but to stop it with a matt sheet or object.

CAUTION

Release of dangerous laser radiation when the sensor is defective.

Use of the sensor with a fractured front panel or loose/exposed laser optics can release dan-

gerous laser radiation.

a) In case of a fractured front panel or loose/exposed laser optics disconnect the laser from

the power immediately.

b) Have the sensor checked by an authorised person (specialist). Do not operate the

sensor until that time.

3.1.2 Functionality

The sensor is used to measure the surface profile of an object along a laser line projected

onto the object. The measured surface profile can be retrieved by the user – either via the in-

tegrated web server, the UDP interface or the SDK (software development kit). Sensors in

the OXM version have additional integrated functions (tools) that allow carrying out geomet-

ric measurements on the profile (such as width, height, circle diameter or angle). These

measurement results are then available via the integrated process interface, switching out-

puts or the analogue output.

Triangulation principle

The sensor works according to the laser triangulation principle:

1. Via a cylindrical lens, a laser beam is expanded to a laser line and projected onto the

surface of the measurement object.

2. The measurement object reflects the laser line.

3. The reflected laser line is projected onto a surface camera in the sensor.

4. The sensor uses the camera image and stored calibration data to calculate the profile of

a measurement object.

Measurement frequency, measurement repeat time and response time

A complete measurement cycle of the sensor consists of the following steps:

1. Exposure and read out

2. Calculation

3. Output of the measurement results

To increase the measurement speed, process steps are executed in parallel. Two situations

are illustrated below: Measurement rate limited by the exposure time (first figure) and meas-

urement rate limited by the calculation time (second figure):

3 | Description Baumer

14 OX200_BA_V1_EN

The time between two exposure periods is called the measurement repeat time, which can

be converted into a measurement frequency. The calculated measurement frequency indic-

ates how many measurement results the sensor can output per second.

n

Formula for calculating the measurement frequency:

▪ Measurement frequency [kHz] = 1 / Measurement repeat time [ms]

3.1.3 Reference surfaces

The purpose of the reference surfaces R1 to R3 presented below is to facilitate alignment of

the sensor during mounting and commissioning.

3.1.4 Field of view of the sensor

The following illustration shows the field of view of the sensor. The sensor can be operated

in both the height mode (object space) as well as the distance mode (sensor space) (see

also Aligning the sensor (height and distance mode) [}76]). In the blind region (CD), the

sensor cannot detect any measurement objects. The presence of measurement objects in

this area can lead to incorrect measurement values.

Transmission and receiving axis

The transmission and receiving axes can lie in the areas shown in blue in the figures below.

The exact axes depend on the position of the object. Objects that should not be measured

should be kept away from this area as they can interfere with the measurement and lead to

incorrect measurement values.

3.2 Operating and display elements

3.2.1 Web interface

The sensor has a web interface that allows to parametrise the sensor and visualise the data.

The sensor contains an integrated web server for this purpose. The web interface is access-

ible through a web browser.

For a detailed description of the web interface, the individual elements of the user interface

and all required operating processes, see Web interface description [}60].

3.3 Interfaces and protocols

The sensor offers a variety of interfaces and protocols (multi-protocol sensor). The available

functions and measuring rates depend on the protocol used.

The sensor supports one client connection per protocol. Read access via the protocols is

possible at any time. Write access is only permissible in the parametrisation mode. Only one

interface at a time can be in parametrisation mode.

OXP version sensor

You can configure and parametrise sensors of the OXP version via the integrated web inter-

face as well as via a freely available software development kit (see also SDK [}39]). With

the OXP version, it is not possible to communicate via process interfaces such as Profinet,

Modbus/TCP, OPCUA, and IO-Link, since the sensor does not supply any measurement

results. The profile data is transmitted via UDP (User Datagram Protocol).

OXM version sensor

You can configure and parametrise the OXM version sensor exclusively via the integrated

web interface (the above-mentioned SDK can be also used for the OXM version, but only

with the functions described in SDK [}39]). Read access to the measurement results and

switching of parameter sets can also take place via the process interfaces Profinet, Modbus

TCP, OPC UA and IO-Link.

For the precise range of interfaces and protocols, please see the data sheet that is available

for download at www.baumer.com/OX200.

3.3.1 Industrial Ethernet [OXM]

Industrial Ethernet protocols (e.g. Profinet) enable the communication between the sensor

and a PLC. In general, the following data can be transferred:

n

General control and status data (measuring rate, time stamp, status of outputs, etc.)

n

Result data (parametrisation of the result data via the web interface)

n

Parameter setups (pre-set parametrisation)

Data is organised in modules in Profinet. This means that the data is summarised in logical

groups and mapped to the existing interfaces. The mapping and evaluation of the data in the

PLC must be configured with the respective manufacturer-specific tool.

The protocol is defined by the respective Industrial Ethernet specification. You can select the

protocol on the sensor and make the relevant settings via the web interface (see Device

Configuration mode [}93]).

Cyclic/acyclic data

During data transfer, a distinction is made between cyclic data and acyclic data:

n

Cyclic data is exchanged periodically as connected measurement results between the

devices and the control (PLC). The desired time period is specified during configuration

of the control. The consistency of the data within a block can be verified via the associ-

ated status data. For example, for valid measurement results it must be ensured that the

sensor is not in the parametrisation mode (parametrisation mode flag is not active).

n

Acyclic data is only transferred between the devices and the control when required and

in case of special events. An example of acyclic data transfer is the exchange of para-

metrisation and configuration data or diagnostic messages between the devices and the

control during ongoing operation or when establishing the connection.
