This parameter indicates the flow metered by the instrument. The value of 32000 corresponds to 100%, the maximum

measured value output is 131.07%, which translates to 41942.

*In case the instrument is prepared for bi-directional measurement, the negative signals with an output range of -

73.73…-0.003% are represented by the range of 41943…65535, whereas the positive signals 0…131.07% are still

represented by the range of 0…41942. (FlowDDE converts the numbers to negative values automatically).

This parameter is used to set the required flow rate for the controller. The signals have the same range as

setpoint range is limited between 0 and 100% (0…32000).

The value of this parameter represents the time it would take to adjust the setpoint if it were changed from 0 to 100%. This

feature can be used to smooth 'nervous' controller behavior, e.g. to reduce setpoint overshoot or undershoot.

The supported range corresponds to 0…3000 seconds. Default value = 0.

Example:

Setpoint Slope

= 100 it will take 10 seconds to adjust the setpoint if it is changed from 0 to 100%. A setpoint change of 20%

will take (20%/100%)*10 seconds = 2 seconds.
