1. The scaled variable is communicated via PROFINET in the "Analog Input Scaled
Variable" module in slot 20 (0x1000). To use a linearized value, use the "Analog Input
Scaled Variable" module.
2. The linearization table can be opened via the Go to linearization table parameter
Table option.
 Menu path: Application → Sensor → Scaled variable → Scaled variable transfer
function
3. Enter the desired table values.
4. The table is activated once all the points in the table have been entered.
5. Activate the table via the Activate table parameter.
Result:
The measured value after linearization is displayed.
• Error message F435 "Linearization" and the alarm current appear as long as the
table is being entered and until the table is activated
• The 0% value is defined by the smallest point in the table
The 100% value is defined by the largest point in the table
9.8 "Simulation" submenu
With the Simulation submenu, the pressure and diagnostic events can be simulated.
Menu path: Diagnostics → Simulation
