4. Set parameter "Ramp end" to stop the simulation when the process value reaches the ramp
end value.
5. Set parameter "Ramp steps" to set the number of steps in the ramp simulation.
6. Set parameter "Ramp duration" to set the time interval (in seconds) for each step in the
simulation.
7. Click "Transfer" button to start the simulation.
The simulated level will initially begin ramping up from the simulation value. When the
process value rises to 100% or falls to 0%, it reverses direction at the same rate. The
simulation will stop based on the ramp end value, but ensure parameter "Simulation mode" is
set to "Disabled" before the current output is returned to automatic control.
Note
Only distance is simulated
Only distance is simulated. Level, space, volume, custome, and mA are derived from the
simulated distance. Echo strength and confidence are set to fixed values during simulation.

Simulation - Application test (Operating chapter)

Application test
You can test the application by varying the actual process value (the preferred test method),
or by simulating changes to the process value.
When simulating a changing process value, run a complete cycle to verify that device
operates as expected. Monitor system performance carefully, under all anticipated operating
conditions.
1. When the device performs exactly as required, programming is complete.
2. If alternate measurement units, or fail-safe action is desired, update the parameters for the
new functionality.
3. If you experience problems with system performance, see Diagnostics and troubleshooting
(Page 155).
If you cannot observe all possible operating conditions by varying the process value, use the
simulation process above to verify programming.
Retest the system each time you adjust any parameters.
8.5.3

Simulation - Diagnostic (Operating chapter)

Diagnostic simulation
Diagnostics can be simulated via a remote engineering system. Diagnostics related to
"Device status", "Limit monitoring and event counter", and "HART status" can be chosen from
a select list to simulate.
