3.9 Basic Parameters and Properties
3.9.1 Introduction
Every parameter has its own properties. These properties are given in a table as shown:
Type Access Range FlowDDE Flowbus® Modbus®
[type] RW

[x]…[y] [FB] [Pro]/[Par] [address]/[index]
Type
Unsigned char 1-byte character
Unsigned char[x] x-byte array (string)
Unsigned int 2-byte unsigned integer
Float 4-byte floating point
Access
R The parameter is read-only
RW The parameter can be read and write
RW

The parameter can only be written when the Init Reset parameter is set to 64. See section
4.1.1, General Product Information for more details.
Range
Some parameters only accept values within a certain range:
[x] Minimal value of the range.
[y] Maximal value of the range.
FlowDDE
Parameter number in FlowDDE. Check section 3.2, “In analog operation following signals are available:
• Measured value (analog output)
•
Setpoint (analog input)
The type of installed analog interface (0-5V, 4-20mA) can be found in the model key of the instrument.
Refer to section 1.5.2.
Setpoints below 2% of the full scale will be interpreted as 0% setpoint.
When operating the instrument through the analog interface it is possible to connect the
instrument simultaneously to RS232 or Modbus®/RS485 for reading/changing parameters
(e.g. controller response or other fluid selection).
