With firmware 2.0, BVS IdentSensor and BVS VisionSensor can also be operated as fieldbus variants in dual-port mode. This application note describes the difference between single-port (SP) and dual-port mode (DP) and explains how to set the modes and what to look out for.

The sensors are sold in single-port (SP) mode on delivery and as the default setting. The single-port mode corresponds to the old "normal" fieldbus mode. However, the GSD file (Profinet) has been updated with firmware 2.0 and must be selected to match the firmware.

Single port means that the two LAN interfaces on the sensor (XF1 and XF2 connectors) are operated separately from each other.

Fieldbus communication takes place exclusively on the XF1 connector in SP mode.

The web interface of the sensors can be accessed exclusively via the XF2/IIOT interface. The FTP/report functions also work via this interface with the full transmission speed of up to 1 GBit/s.

In order to be able to use the full functionality of the interfaces, both LAN interfaces on BVS IdentSensor / VisionSensor are required, each with a separate cable.

With firmware 2.0 there is the option of dual port mode (DP). The setting for this can be found in the web interface in configuration mode in the system settings.

Note: To be able to make this setting, it is essential to access the web interface of the sensors once via the GigE cable (XF2 connector).

An X-coded M12 Ethernet cable is required for this.

For dual-port mode, the correct GSD file with the appropriate head module (SP or DP) from the hardware catalog must be used in Siemens TIA.

Caution!

If the settings for single or dual port are subsequently changed, the fieldbus communication may no longer work.

In dual-port mode, BVS IdentSensor / VisionSensor act as a switch and the web interface and the fieldbus can be accessed from both adapters XF1 and XF2. The web interface can be accessed via the IP address set in the IIOT network tab of the system settings (default 192.168.10.2). The fieldbus IP address can be set in the Process communication tab (EtherNet/IP only) or is assigned by the PLC. The bandwidth of the EtherNet adapter is reduced to 100 MB/s.

This makes it possible to either integrate the sensors into a fieldbus via just 1 cable with a simultaneously accessible web interface or to loop the fieldbus cable directly through the sensor. Please note the following for the plug connectors on the sensors:

XF1 = D-coded 4-pin

XF2 = X-coded 8-pin

No access to the web interface/ sensor not accessible in DP mode

• Both LAN adapters must not be connected to the same network/subnet. If in doubt, use only one line to test the connection via the sensor IP address (default 192.168.10.2).
• Check whether the laptop is in the correct network (matching the sensor settings).
• If in doubt, temporarily reset the IP addresses (there is an auto-setup button on the top of the sensor, press it for longer than 12 seconds)

PLC program no longer works after firmware update

• The GSD file must be updated in the PLC project (alternatively, downgrade the firmware again)
• The sensor settings must match the selected GSD file (SP or DP)
