3 Remote configuration and monitoring OTAC* The BeanScape application allows the user to view all the data transmitted by the BeanDevice AX-3D With the OTAC (Over-the-Air configuration) feature, the user can remotely configure the BeanDevice AX-3D. OPC Server** Several data acquisition modes are available on the ce AX-3D : **OPC server is only available on the BeanScape Premium+ AX-3D *Over-the-Air Configuration BeanDevi- Low Duty Cycle Data Acquisition mode (LDCDA): the data acquisition is immediately transmitted by radio. The transmission frequency can be configured from 1s to 24h. Alarm Mode : the measured value is transmitted by radio whenever an alarm threshold (fixed by the user) is detected (4 alarm threshold levels High/Low). Survey Mode : operates like the Alarm mode but the device sends frequently a beacon frame informing its current status. Streaming Packet Mode: all measured values are transmitted by packet within a continuous flow at 5000 samples per second maximum Streaming Mode: all measured values are transmitted in real-time within a continuous flow at 100 samples per second maximum Math Mode : Values such as the mean value, minimum value, maximum value and standard deviation are calculated on sample time series and transmitted by radio. The BeanScape Premium+ integrates an OPC DA server (Data Access). OPC DA is particularly well suited for real time measurement and data sharing. Each data/measurement can be associated to a tag or its attributes and shared with one or many OPC clients. Antenna Diversity While the vast majority of wireless sensors shows their limits in harsh industrial environment, the BeanDevice AX-3D integrates an innovative antenna diversity design, allowing to optimize the radio link quality in environments subject to random and diverse disturbance. Antenna diversity improves both the quality and reliability of a wireless link by 30%. 3

4 Embedded Data Logger up to 1,000,000 data acquisition records The BeanDevice AX-3D integrates an embedded Datalogger, which can be used to log data when a Wireless Sensor network can not be easily deployed on your site. All the data acquisition are stored on the embedded flash and then transmitted to the BeanGateway when a Wireless Sensor Network is established. The Datalogger feature is compatible with all the data acquisition mode available on your BeanDevice AX-3D : LowDutyCycle Data Acquisition Alarm Math Streaming & Streaming packet ( maximum data rate : 1 Ksamples per second for each axis) Example: Vibration Analysis on windmills blades The BeanDevice AX-3D is configured with its Datalogger feature. A standalone installation of the BeanDevice AX-3D will be done on the windmills blades, without the necessity to be connected to the BeanGateway. Once the blades starts rotating, each data is recorded on the embedded flash. When the windmill is for maintenance, a technician working on the site can send a request for a log transmission. Then the BeanDevice AX-3D starts sending all its logs. If all the logs are sucessfully transmitted to the BeanGateway, the flash memory is erased and new logs will be recorded. 4
