1.
General
This document shows how to integrate scanCONTROL sensors into PROFINET environments using the 2D/3D Gateway.
To ensure bi-directional communication with the sensor, the gateway uses Modbus/TCP. In this way, measuring values can be requested
and control commands can be sent. Thus no sensor functionality is lost when using the gateway.
In the following the necessary settings in scanCONTROL Configuration Tools, the configuration of the gateway and the integration into
TwinCAT will be shown.

scanCONTROL Configuration Tools
2D/3D Gateway II
Hilscher SYCON.net system configurator

24V power supply unit
For correct installation of the software components, please consider the
installation guides coming with the different software packages.
2.2
Figure 1: 2D/3D Gateway II
Network structure example
In this example, the scanCONTROL SMART sensor is connected to the X3 Ethernet port of the gateway. At X2, the fieldbus master (in
this case a Siemens PLC) is connected. The two X3 ports are switched each and have a maximum transfer rate of 100 Mbit/s.
Therefore, the choice of the port doesn’t make any difference. The X3 ports are used for the Modbus connection and X2 for PROFINET
connection.
Figure 2: Schematic network structure
As long as the transfer rate is less than 100 Mbit/s, the sensor can be configured via the second X3 port of the gateway. Operating a
second sensor is also possible with the second X3 port. If you want to integrate three or four sensors via the gateway, a gigabit-ready
Ethernet switch is necessary. If no switch is available, you can configure the sensor via a direct Ethernet connection between the PC

Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
and the subscriber and, if necessary, subsequently reconnect to the next participant.
When using a switch, please make sure if the device can handle the amount of communication data.

3. Sensor configuration
To enable the gateway to request measuring values from the sensor, the sensor has to be correctly configured. How to do this with
scanCONTROL Configuration Tools 6.7 is shown below. An already fully configured measuring task (e.g. an offset or angle
measurement) is necessary. The following steps are then necessary to configure the sensor.

4. Gateway configuration
To configure the gateway the Hilscher SYCON.net system configurator is needed. It is included in the Gateway Solutions DVD, which is
available under hilscher.com/downloads.
4.1
Configuration of the secondary network (sensor side)
The following configuration steps are necessary for every type of communication / primary fieldbus:
• General settings
1. Connect the gateway to a PC via USB cable.
2. Open the Sycon.net software and log in as admin user.
If the software is opened for the first time, a new admin user can be created by choosing a user name and a password.
3. Create a new Project with “File”-> “New” and save it with “File” –> “Save as…”.
4. Search for “NT 151-RE-RE” in the search bar on the right side.
5. Add the “NT 151-RE-RE” device to the project via drag-and-drop. Double-click the pictogram.

Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
Figure 8: Add NT 151
6.
You can add a physical device to the project in “Device Assignment”. If necessary, click “Scan” and then select the correct
device. The device has to be listed under “suitable only”. “Apply” will confirm the settings.
If the device is not found, following actions can help: checking the USB-connection and the drivers, selection of the COM Port
in “netX Driver”, restarting the ODMV3 service.
Further information and support can be found in the Hilscher documentation.

Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
4.2 Modbus/TCP configuration
Regardless of the target fieldbus protocol, first the Modbus/TCP connection with the sensor has to be established:
1.
2.
Double-click the gateway pictogram in the main view. Select “Settings” in the pop-up window.
For the “Secondary network (Port X3)” select “Open Modbus/TCP”.
Then confirm with “OK”.
Figure 10: Select secondary network
3.
4.
5.
Back in the main view, right-click the gateway and select “Configuration”  “Open Modbus/TCP”.
In “Configuration” change the “Protocol mode” to “Client” and “Data swap” to “No”.
Deselect “DHCP” and check the “Enable” boxes. Now you can enter the desired IP configuration. Please make sure that the
X3 port of the gateway is in the same subnet as the sensor(s).
Figure 11: Configuration of Open Modbus/TCP

Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
6.
7.
8.
To add Modbus commands, change to the “Command Table” section and click “Add” once for each new command. These
commands are basically telling the sensor how to communicate with the sensor(s).
For each command, enter the IP addresses of the sensor(s). It is not recommended to operate more than 4 sensors on one
gateway. The max. frequencies with which the data can be polled from the sensors directly depend on the number of sensors
connected (refer to chapter 5 for more details).
The function code “Read Input Registers” reads the 32 measurement registers (“Register/Coilanzahl”) of the the sensor. By
setting the cycle time to 0 ms the values will be fetched as fast as possible.
Function code “Preset Multiple Registers” enables controlling the sensor by writing on the Holding Registers 32-37. Therefore
the Trigger should be set to “Changed Data”. Therewith the command is only executed if new data was received on the
primary network.
Furthermore the function code “Read Holding Registers” makes it possible to read Holding Registers 36 & 37. Through this
the GETQ command can be used to get settings of the sensor(s). The cycle time can be selected freely.
Click “Apply” to confirm.
If the 2D/3d Gateway should communicate with several sensors, the listed function codes (8) have to be duplicated with
accordingly adjusted IP addresses (7).

4.3 Signal configuration
1. Then select “Signal Configuration” on the left in the navigation area. Here, the signals for the previously determined
commands are reflected by modules. The “word area” module types are converted into “byte arrays” so that the signals can
be associated with the individual bytes in the PROFINET network.
2. To do this, select the first line to show the module details. Right-click under “Type” and select “Edit Signal…”.
3. In the dialog box that appears, select “byte” as the new data type, set the number to 12, and put a check mark in the box
next to “Apply as Array”.

5. Performance
This chapter states the maximum frequencies with which the gateway converts the measured values. To ensure valid performance tests
a high-end PLC was used. I/O cycle times were set to 1 ms or less. All limits were empirically tested in a lab environment, so the
maximum transmission frequencies might deviate in real-world applications. The maximum measurement frequencies depending on the
number of sensors can be seen here:
# Sensors

6. Communication with a PLC
The integration of the gateway into an automation system based on a Siemens PLC will be shown with Step 7 V14. Furthermore, the
basics of sensor data exchange are described.
6.1
Integration
To establish a connection between gateway and Siemens PLC, the device has to be added as PROFINET IO Device in the TIA Portal.
Therefore the previously created device description file of the gateway has to be installed. This already includes the modules which
were specified in the gateway configuration.
• Install device description file
1. Click “Options” and then “Manage general station description files (GSD)”.
2. In the window that appears, specify the folder in which the description file is located.
Figure 21: Managing the General Station Description File

5. Select the gateway in “Network view”.
6. Change to the settings of the Ethernet addresses in “Properties”  “General” and assign an address for the PROFINET IO-Device.
The device must be in the same address range as the PLC.
Figure 25: Gateway PROFINET Interface
18
Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
• Assigning Device Names
When the device is configured, the device name and the IP address must be transferred to the PROFINET device.
1.
2.
3.
To do this, right-click the gateway and select “Assign device name”.
“Update list”
Based on the MAC address, the gateway can be uniquely identified. Select the device “netTAP 151” and click “Assign name”.
Figure 26: Assigning device name
The settings are now complete. After transferring and downloading to the PLC, the Modbus register can be reached by 3DInspect via
the gateway hardware addresses (see Figure 27).

Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
6.2
Interpretation of data / sensor control
• Input data / Conversion of measurement values
The input data represents the measurement values which are transmitted in sensor coordinates and therewith have to be converted to
REAL values on the PLC side. To do this conversion the incoming data has to be interpreted as an integer and then put into a formula.
Depending on the position and type of the data that will be transmitted, see register assignment (Figure 6) the data has to be
interpreted the right way and depending on the type of the data the right formula has to be chosen.
20
Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
Example:
Following data will be transmitted:
Figure 28: Example register assignment
Therewith following values will be received at the 64 Byte Input module:
Byte 1:
Byte 2:
Byte 3:
Byte 4:
Byte 5:
Byte 6:
0
3
64
138
113
105
Calculation of profile number:
The first 4 bytes represent the profile number (2 registers), those bytes have to be interpreted as 24 bit non signed integer.
0 * 2^24 + 3 * 2^16 + 64 * 2^8 + 138 = 213130
Calculation edge X:
The bytes 5 & 6 represent the edge. Those bytes have to be interpreted as 16 bit non signed integer.
113 * 2^8 + 105 = 29033
The value then has to be put into the suitable formula with the suitable scaling factor (0.002 at scanCONTROL 30XX-50).
y = (29033 – 32768) * 0,002 = -7,470
• Output data / sensor control
Output data specifies a control command which will be sent to the sensor. The command is built of 6 registers respectively the twelve
configured output bytes and consists of the following values.
Bytes 1-2
Bytes 3-4
Bytes 5-6
Bytes 7-8
Bytes 9-10
Bytes 11-12
Function
Access (write or read)
Always 0 (reserve)
Control register (lower 16 Bit)
Control register (upper 16 Bit)
Data (lower 16 Bit)
Data (upper 16 Bit)
Example: Switch off laser
0x0002 (SETQ = write)
0
0x0824
0xF0F0

0
The control registers addresses as well as the corresponding values can be found in the document OpManPartB. The document is part
of the scanCONTROL documentation.
For the conversion of the measurement values as well as the control of the sensor exists a TwinCAT example project. This should
always be used as example for an own integration and doesn’t represent the ideal for every use case.
7. Transmit the gateway configuration data to other devices via memory card
With the help of the memory card management of the gateway in SYCON.net, an already downloaded configuration can be copied
together with the firmware from the internal loading memory to an SD memory card, which is plugged into the gateway. Afterwards the
card can be removed and plugged into other gateways. As soon as the device is connected to the power supply, the configuration data
on the memory card is transferred to the internal loading memory. In this way several gateways can be easily brought to the same
configuration status without the need to connect the configuration PC to every single device. Therewith the SD-card also works as
backup solution.
21
Connection Instructions scanCONTROL // 2D/3D Gateway II // PROFINET
Prerequisites:
• A FAT formatted SD-card.
• Suitable configuration was created and downloaded to the 2D/3D Gateway
• Windows PC with SYCON.net is connected via USB to the 2D/3D Gateway
• 2D/3D Gateway is supplied with power
Transfer configuration data to the memory card
First the device assignment has to be checked or done. Therefore, the configured SYCON project has to be opened or a new project is
opened and the device “NT 151-RE-RE” is added.
1.
2.

6.
In configuration mode, double-click the gateway icon in the main view. To change into configuration mode, right-click the
gateway  “Disconnect”.
In “Device Assignment” a physical device can be added to the project. If necessary, click “Scan” and then select the correct
device. “Apply” will confirm the settings.
If the device is not found, following actions can help: checking the USB-connection and the drivers, selection of the COM Port
in “netX Driver”, restarting the ODMV3 service.
Further information and support can be found in the Hilscher documentation.
Insert the SD memory card into the gateway until it locks into place. You may have to remove the write protection.
Change to “Memory Card Management” in the navigation area.
In the area “Directory” in the field “Folder” the data system of the loading memory of the gateway is displayed. The end of the
list should contain the “SDMMC” data system of the SD memory. If not, the memory card has to be removed from the device
and inserted again into the gateway. Then refresh the dialog window (e.g. briefly change to another element of the navigation
area).
Clicking “Backup” copies the data in the loading memory of the gateway to the SD memory card. This might take several
minutes (please note to the clock symbol at the bottom of the dialog window). Confirm with “OK” and close SYCON.net.
Figure 29: Memory card management
Transfer configuration data with an SD memory card to another device
1. Remove the memory card from the first gateway and insert it in the other device.
2. Connect the device to the power supply or interrupt the power supply for a short time if it is already connected.
3. The device loads the configuration data from the memory card into its own loading memory. The SYS LED quickly flashes
green and yellow for approx. eight seconds, then yellow for ten seconds, then the LED is off for a short time and finally it
should stay green. The gateway automatically starts with the loaded firmware and configuration.
4. Remove the SD memory card from the 2D/3D Gateway.
