7.22 Simulation

The direction of fault current, which is to be selected for a current saturation interrupt, can be
programmed according to your needs. The following settings are possible under the current
saturation menu:
Active interrupt value
Inverse interrupt value
Saturated interrupt value
Inverse saturated interrupt
value

Overview of simulation

Description
With the "Simulation" diagnostic function, you can receive and process (quasi-)
measurement data onsite or in the control room without having process pressure or a
temperature value. This allows you to run individual process sequences in the "cold" state
and thus simulate process states. In addition, if you inject simulation values you can test the
line routing from the control room to the individual transmitter.
The value to be simulated can be provided as a fixed value or in the form of a ramp function.
Simulation of pressure and temperature values is handled in the same way in terms of
parameter settings and function, so the following will only deal with the general simulation
procedures "Fixed value" and "Ramp function".
For reasons of safety, all simulation data are held only in the user memory (RAM). This
means that when the device is restarted any simulation which may be active will be shut
down. You can simulate the pressure and both temperature values. It should be noted here
that changing the temperatures by simulation will have no effect on the measured pressure
value.

The applicable settings are those under the current interrupt type menu
command.
The applicable settings are the inverse settings under the current
interrupt type menu command.
The fault current is output in the direction of current saturation.
The fault current is output in the opposite direction to current saturation.
