Parameter assignment
9.3 Parameter assignment over remote operation
End diagnostics simulation
You close the simulation in the "Diagnostics simulation" tab:
● To disable a specific diagnostic action, click "Off" (under the "Action" field).
● To end the diagnostics simulation, click on the "Disable" button.
NOTICE
The device display shows a simulated diagnostic status and does not react to diagnostic
events of normal operation.
When diagnostics simulation is enabled, diagnostic events of normal operation are neither
recorded nor evaluated.
When diagnostics simulation is enabled, the device display shows the currently most critical
simulated diagnostic status.
● Stop diagnostics simulation immediately after use as follows:

Customized characteristic curve

9.3.5.1

Introduction

For special applications, a customized characteristic curve is available.
This application is used, for example, for volume measurement in vessels with unusual shapes.
You define the relationship between inlet pressure and outlet current according to your user-
specific requirements.
You have up to 32 breakpoints available for this, which you enter using the engineering system
and display graphically.
Example
For measurement with the customized characteristic curve, you set the following values, for
example:
Damping value:
Lower range value:
Upper range value:
Application:
Unit:
Lower scaling point:
Upper scaling point:
146
– Click "Disable" in the "Diagnostics simulation" tab before you close the "Diagnostics"
dialog.
– Alternatively, you can restart the device.
