Overview of simulation
Simulation functions help you when commissioning parts of the system and the transmitter.
You can generate process values without recording real measured values. The value range
of simulated process values can be tested fully: This makes the simulation of errors possible.
From the output of the pressure transmitter, you can get ever closer to the sensor and check
the measurement and function blocks.
The display indicates active simulation with an "Si" in the mode display.
7.10.2
Simulating output
By simulating the output, you can make process values available at the output of the
pressure transmitter for cyclic data transmissions using acyclic write access. This allows you
to test process value processing in the automation program.
Procedure
To simulate the output, make the following settings:
1. Select output simulation.
2. Set the target mode to manual (MAN).
3. Enter the desired output value, the quality, and the status.
4. Transmit the settings from the program into the transmitter.
The behavior of the output can be observed e.g. in SIMATIC PDM or using a variable table
(VAT component).
To return to normal operation afterwards, set the target mode to AUTO.
