Table 1. Modbus configuration data registers (writable)
Register number Address Description Data format Unit / Valid range
Compensation setpoints
769 0300hex Pressure compensation setpoint 32-bit float

Unit: hPa

Default: 1013.25 hPa

821 0334hex

Temperature compensation setpoint. If a value is written to this register, probe uses it instead of its own temperature measurement.

32-bit float Unit: °C
General
2561 0A00hex Device tag Text Text string of 24 bytes in UTF-8 encoding
Sensor purge
773 0304hex Sensor purge interval 32-bit float Unit: min

10 ... 14400

1283 0502hex Interval purge on/off 16-bit boolean

0 = Off

1 = On

1284 0503hex Startup purge on/off 16-bit boolean

0 = Off

1 = On

Filtering
795 031Ahex Measurement filtering factor 32-bit float

Range: 0.000 ... 1.000

1.000 = Reading shows 100% of the most recent measured value (no filtering, default)

0.01 ... 0.99 = Reading shows 1 ... 99% of the most recent measured value and part of the previous reading (filtering is applied). For example, "0.9" means that the filtered measurement reading = 90% of the most recent measured value + 10% of the previous reading.

1282 0501hex Enable or disable measurement filtering using the user-defined filtering factor (register 031Ahex) 16-bit boolean

0 = Off

1 = On

Communication
1537 0600hex Modbus address 16-bit integer

1 ... 247

Default: 240

1538 0601hex Bit rate enum

0 = 300

1 = 600

2 = 1200

3 = 2400

4 = 4800

5 = 9600

6 = 19200

7 = 38400

8 = 57600

9 = 115200

1539 0602hex Parity, data, stop bits enum

0 = None, 8, 1

1 = None, 8, 2

2 = Even, 8, 1

3 = Even, 8, 2

4 = Odd, 8, 1

5 = Odd, 8, 2

(default: 1 = None, 8, 2)

1540 0603hex Response delay 16-bit integer

Unit: ms

Range: 0 ... 1000
