3.1.2 Functionality

The sensor measures the surface profile of an object along the projected laser line. Additional

sensor functions (tools) enable geometric measurements on the profile of height, width, or

edge). These measured values are provided at the integrated process interface, the switching

outputs 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 sur-

face 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.

nVaried measurement functions, such as edge, width, gap.

nPosition tracking of evaluation windows.

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 measured values

Process steps are executed in parallel to increase measuring speed. The illustrations below de-

scribe two situations: Measurement rate limited by exposure time (fig.1) and measuring rate lim-

ited by calculation time (fig.2):

Ill.6: Measurement rate limited by calculation time

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

converted into a measurement frequency. The calculated measurement frequency indicates

how many measured values the sensor can output per second.

nFormula 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.

Ill.7: Reference surfaces

R1 Reference surface 1; positioned parallel

to the side surface at a right angle to

The illustration below shows the measurement field of the sensor. The sensor can be operated

in both height mode (object space) as well as in distance mode (sensor space), see also Align-

ing the sensor (height and distance mode) [}47]. Within the blind region (CD), the sensor will

not detect any objects.

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 mea-

sured values.

3.2.1 Web interface

The sensor features a web interface enabling sensor parameterization and data visualization.

For doing so, the sensor integrates a web server. Web interface access is via web browser.

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 respectivvely applied protocol.

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

ble at any time. Write access is only permissible in the parametrisation mode. Only one inter-

face at a time can be in parametrisation mode.

Sensor parameterization and configuration only via the integrated web interface. Read access

to the measured values and for changing parameter sets is also enabled via the process inter-

faces Modbus RTU 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/OX100.

3.3.1 Modbus RTU

Modbus RTU is a standardized protocol, here based on a serial client/server communication via

RS485. Many PLCs support this protocol already in the state of delivery or allow for retrofit by

software module. For PC-based systems, libraries for different programming languages are

available. The standard is freely available on the website of the Modbus organisation. Visit

http://www.modbus.org

For information on Modbus TCP commissioning refer to Set up RS485 interface with Modbus

RTU [}31].

Mapping the sensor functionality on the Modbus data model

The functionality of the sensor can be accessed by reading or writing entries in the tables Dis-

crete Inputs, Input Registers, and holding registers. The following Modbus function codes

(FC) are supported:

nRead Discrete Inputs (FC 02)

nRead Input Registers (FC 04)

nRead Holding Registers (FC 03)

nWrite Single Holding Register (FC 06)

nWrite Multiple Holding Registers (FC 16)

The following FC tables are independent of each other, so the same address may represent dif-

ferent functions in each table. Basically, Modbus registers are limited to 16bits. Therefore,

when reading or writing larger values, several registers must be taken into account for the re-

spective operation. Reading or writing only part of the specified address is not supported. Less

significant words are saved under the inferior address. Example:

nValue (UInt32): 0x12345678

nRegister Address n: 0x5678

nRegister Address n+1: 0x1234

INFO

1 Modbus register corresponds to 2 bytes. If the data type of a sensor parameter is wider than a

2 byte Modbus register, the parameter is divided among several Modbus registers. The less sig-

nificant bits are located at the smaller address and the more significant bits at the larger ad-

dress (Little Endian).

In general, all registers enable write and read. Reading a register with write access only will re-

ply 0xFFFF.

(Process Data Unit) specifies the start register address and the number of registers. PDU regis-

ter addressing starts with zero. For this reason, input registers 1-16 are addressed as 0-15.
