3.6.2 Basic measurement and control parameters
The list below provides the most basic parameters for digital communication with the instrument.
For more detailed information regarding operation parameters, see document nr. 9.17.023: Operational
instructions for digital instruments.
Measured Value (Measure)
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned int R 0…41942 8 1/0 0x0020/33
The ‘Measured Value’ indicates the amount of mass flow or pressure metered by the instrument. The signal of
0...100% will be presented in a range of 0...32000. The maximum measured value output is 131.07 %, which is: 41942.
A floating point variable of the measured value, ‘Fmeasure’, is also available in the capacity and capacity unit for which
the instrument has been set, see section 4.
Setpoint
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned int RW 0…32000 9 1/1 0x0021/34
The ‘Setpoint’ is used to set the required mass flow rate or pressure for the controller. The signals have the same
range as the measured value, only the setpoint is limited between 0 and 100% (0…32000). A floating point variable of
the setpoint, ‘Fsetpoint’, is also available in the capacity and capacity unit for which the instrument has been set, see
section 4.
3.6.3 Basic identification parameters
User Tag
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[16] RW - 115 113/6 0xF130…0xF136/61745…61751
The ‘User Tag’ parameter allows the user to give the instrument a custom tag name, with a maximum of 16 characters.
It is advised however to limit the user tag name up to 7 characters when using the Bronkhorst® E-7000 readout and
control modules. These modules can display the tag name of an instrument only up to 7 characters.
Customer Model
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[16] RW  - 93 113/4 0xF120…0xF127/61729…61736
This parameter is used to add extra information to the model number information, such as a customer-specific model
number.
Serial Number
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[20] R - 92 113/3 0xF118…0xF11F/61721…61728
This parameter consists of a maximum 20-byte string with instrument serial number for identification, for example:
‘M1111111A’.
BHT Model Number
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned char[23] R - 91 113/2 0xF111…0xF117/61713…61719
This parameter shows the Bronkhorst® instrument model type information.
