8.20 Simulation (only for SITRANS TR300)
With the "Simulation" diagnostic function, you can receive and process (quasi-)
measurement data without having a process value at the device. This allows you to run
individual process operations in the "cold" state and thus simulate process states. In
addition, you can check the wire layout for the analog output by adding on the simulation
values.
The value to be simulated can be predetermined as a fixed value or in the form of a ramp
function. The following simulations for the measuring input and analog output are possible:
Measuring input:
●
Fixed value simulation or ramp simulation for a primary process variable
● Fixed value simulation or ramp simulation for electronics temperature
Measuring outputs:
●
Fixed value simulation of the analog output
Simulation of the primary process variable, electronics temperature, and analog output are
managed the same way for parameterization and function. For this reason, only the general
simulation processes "fixed value" and "ramp function" are described in the following using
the measuring input as an example.
For safety reasons, all simulation data are held only in the working memory. This means that
when the device is restarted any simulation which may be active will be shut down.
