Simulating input
By simulating the input, you can check the following functions:
● Adaptation of the measured value to the required process variable
● Monitoring of the process limits you have set
● Electric damping
● Failure behavior
Procedure
To simulate the input, make the following settings:
1. Select input simulation.
2. Set the target mode to AUTO.
3. Select the simulation mode "Released".
4. Enter the desired input value, the quality, and the status.
5. Transmit the settings from the program into the transmitter.
You can observe the behavior of the input in e.g. SIMATIC PDM.
To return to normal operation afterwards, you must turn off the simulation.
7.10.4
Simulating the pressure sensor
By simulating the pressure sensor as a fixed value or a parameterizable ramp, you can
check the following functions:
● Calibration
● Check the zero-point adjustment
● Reaction to violation of sensor limits
● Linearization
● Projection onto the working range
You can make the simulation value dynamic with a parameterizable ramp. The simulation
value then goes from a starting value (v
1
) in a step function to a final value (v
2
), staying at
each level for the given step interval (t
v
). At the final value, the direction reverses.
