Simulate Ramp Function; Simulate Diagnostics - Siemens SITRANS P Operating Instructions Manual

Parameter assignment
9.3 Parameter assignment over remote operation
The diagnostic ID "Cb" is displayed on the device.
Note
The simulated pressure value has a direct effect on the configured process value (e.g. volume
or flow rate) and thus on the current output dependent on it.

Simulate ramp function

To simulate a ramp function via remote operation (e.g. SIMATIC PDM), follow these steps:
1. For the "Simulation mode" parameter, set the "Ramp" option to simulate a changing
pressure value.
2. Select the pressure value ("Process value") to be simulated from the drop-down list under
the "Simulation selection" parameter.
3. For the "Simulation value" parameter, set the desired start value for the simulation.
4. Set status to be simulated for the "PV status" parameter.
5. Set the "Ramp end" parameter .
6. Set the "Ramp steps" parameter to define the number of steps in the ramp simulation.
7. Set the "Ramp duration" parameter to define the time interval (in seconds) for each step in
the simulation.
8. Click "Transfer" to start the simulation.
9. For the "Simulation mode" parameter, set the "Disabled" option to stop the simulation.
Note
The simulated pressure value has a direct effect on the configured process value (e.g. volume
or flow rate) and thus on the current output dependent on it.

Simulate diagnostics

Procedure
To simulate diagnostics via remote operation (e.g. SIMATIC PDM), follow these steps:
1. Open the "Device" menu in SIMATIC PDM and select "Simulation > Diagnostics".
2. To put the device into simulation mode, press the "Enable" button in the "Simulation
diagnostics" tab.
(Button switches between "Enable" and "Disable").
3. Select the diagnostics you want to simulate from the drop-down box of the "Diagnostics"
field.
4. Select "Action" for each selected diagnostic action to be simulated: "On" or "Off".
5. To start the simulation, click on the "Apply and transfer" button.
