7.22.2
Simulation with a ramp function
Description
In addition to the adjustable fixed values for all three simulation paths, you can, as a second
option, also configure one ramp function in each case. Adjustable lower and upper values
together determine the limits between which the simulation values with a rising or falling
tendency can move. The step width can be calculated with the step number, which is also
adjustable. You can specify the rate of rise of the ramp via the duration of the individual ramp
steps.

7.22.3
Simulation as fixed value
Description
Taking the physical unit into account you can set a fixed simulation value for all three
possible simulation paths. You can simulate the pressure value and both temperature values
simultaneously. While pressure simulation is activated, the transmitter will not react to
changes in the process pressure. The output value for the current adjusts itself in
accordance with the preset pressure value. Simulation of the temperature values has no
effect on the current output. It can only be observed via HART communication.
