After power-up the control mode will be set to ‘Analog input’ or ‘BUS/RS232’, depending on the customer’s default
setting for analog or digital operation. Except when the actual control mode setting is other than 0, 1, 9 or 18 the
actual control mode setting is maintained. For more information see parameter ‘IOStatus’, section 4.2.2.
For dual interface operation or slave factors, see document nr. 9.17.023: Operational instructions for
digital instruments.
4.1.2 Identification
See also section 3.6.3.
Firmware Version
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[5] R - 105 113/5 0xF128…0xF12A/61737…61739
Revision number of firmware, e.g ‘V1.11a’.
4.1.3 Fluid information
The following parameters give information about the selected fluid range .
Fluid Number
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char RW 0…7 24 1/16 0x0030/49
The ‘Fluid number’ is a pointer to the set of calbration parameters. Each selectable fluid has its own set of calibration
parameter values. Parameter value 0 = fluid 1 and parameter value 7 = fluid 8. Up to eight fluids can be stored in an
instrument. Default value = 0 (fluid 1).
Fluid Name
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[10] RW  - 25 1/17 0x8188…0x818C/33161…33165
This parameter consists of the name of the selected fluid number, e.g. ‘Air’.
Fluid Unit
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[7] RW  - 129 1/31 0x81F8…0x81FB/33273…33276
The ‘Fluid Unit’ can be read by parameter ‘Capacity Unit’. This parameter contains the unit in maximal 7 characters.
Fluid Capacity (@100%)
Type Access Range FlowDDE FLOW-BUS Modbus
Float RW  ±1E-10… ±1E+10 21 1/13 0x8168…0x8169/33129…33130
Capacity is the maximum value at 100% for direct reading in sensor readout units.
Fluid Capacity (@0%)
Type Access Range FlowDDE FLOW-BUS Modbus
Float RW  ±1E-10… ±1E+10 183 33/22 0xA1B0…0xA1B1/41393…41394
This is the capacity zero point for direct reading in sensor readout units.
For using the ‘Capacity Unit Index’ or ‘Capacity Unit’ parameters, see document nr. 9.17.023: Operational
instructions for digital instruments.
