The analog input signals are digitized and output over the fieldbus interface.
Page 15: Block Diagram And Potentials
3.2 Block diagram and potentials Figure 1 Block diagram of model 9251 fieldbus controller The PLC inputs and outputs, TTL inputs and supply voltage are galvanically isolated from the actual measurement electronics and accordingly have their own ground connections. The permissible voltage of the respective connections to PE is 20 V.
Page 16: Suitable Sensors
Sensors with standard signal (process signal) 3.6 Automatic sensor recognition of burster TEDS The controller uses the burster TEDS (Transducer Electronic Data Sheet) to provide automatic sensor recognition, i.e. the instrument reads the relevant sensor specification from an EEPROM fitted in the sensor connector and can then use this data to perform the necessary channel configuration automatically.

The controller then reads the TEDS chip of the connected sensor and parameterises itself accordingly. Hinweis: If a (valid) sensor with a TEDS chip is not connected, you cannot select burster TEDS. If it is determined when reading in that a meaningful device parameterisation cannot be determined from the available information, the process is cancelled and the previous setting is retained.

Page 35: Calibration Of The Controller With Sensors

Other terms: → Rated load Upper scale value or analog value → Zero signal Zero point, zero signal without assembly parts, lower calibration value → Output signal, rated output in preferential measurement direction, upper Rated output calibration value 8.1.1 Calibration with physical variable by the teach-in method The teach-in method involves the two-stage online teach-in of sensor data to the controller, where two states are taught in sequentially.

Page 40: Calibration Using The Test And Calibration Certificate
8.1.2 Calibration using the test and calibration certificate This procedure is a two-point calibration in which you enter the required data directly into the controller. All necessary calibration data can be found on the test and calibration certificate of the strain gage sensor.
Page 41 For two-point calibration, enter two points in succession. The first point is the zero point under no load (lower scale value or analog value), and the second point is the final value (upper scale value or analog value), for example. Hinweis: It does not necessarily have to be zero point and final value, as in principle any two pairs of values are sufficient.
Page 42 1. Start the DigiVision configuration and evaluation software and make sure that the controller is connected correctly and appears in the device list. 2. Click “Import parameters from device (online)” in the left-hand menu bar. When you do this, you import the parameter data of the strain gage sensor saved in the controller into the DigiVision configuration and evaluation soft- ware.
Page 43 6. Enter the upper scale value or analog value of the measurement range of the strain gage sensor. For force sensors, this is usually the rated load of the sensor. In our example, the rated load equals 100 N. 7. You need to enter a corrected value for the rated output of the strain gage sensor in the prefer- ential measurement direction.

If the initialization was successful, the model 9250 instrumentation amplifiers show their channel number in the LED field. If the model 9251 fieldbus controller was not recognized, the status LED on the model 9250 instrumentation amplifiers flashes continuously with a 1-1-1 pattern. When module detection is complete, the status LED flashes continuously and slowly.

(scanner) and device (adapter) during each cyclical access. The device is controlled via the data transmitted from the controller (scanner) to the device (adapter). With the 9251 EtherNet/IP device, these data always consist of 16 bytes. The function of these 16 bytes is explained in Section 11.7.

Configuration of the input size 11.4 EDS file The current EDS file can be downloaded from the burster website: www.burster.de. The EDS file contains the EtherNet/IP configuration information for the model 9251 fieldbus controller. The structure, content and coding of these device description data are standardised so that any EtherNet/IP devices can be configured with configuration tools from different manufacturers.

IEEE 754. This can lead to problems, depending on the type of PLC used. Cause With the 9251 fieldbus controller, the sign bit is transmitted last. Some PLCs expect this byte in the highest of the four addresses, not in the lowest one. This inevitably leads to a misinterpretation of the numerical value.

Each hardware module (measurement channel) has the same data structure and length, including the 9251 fieldbus controller. The first data block is always the 9251 fieldbus controller, the second data block is the first 9250 measurement channel on the left-hand side and the third data block represents the second 9250 measurement channel on the left-hand side of the fieldbus controller (see Figure 43 on Page 98).

Each measurement channel has the same data structure and length, including the bus coupler. The first data block is always the 9251 fieldbus controller, the second data block is the first 9250 measurement channel on the left-hand side and the third data block represents the second 9250 measurement channel on the left-hand side of the bus coupler etc.
