PROFIBUS PA Parameters
10.1 Measured Values
Note
If the sensor status changes before the delay interval is complete, the timer is reset to its
initial value and restarted.
Failsafe mode
If the Transducer Block delivers a measured value accompanied by a status message
classifying the quality as bad (for example Bad, sensor failure), the Discrete Input Function
Block can react with one of three possible preset options.
Failsafe Mode
The default value is used as the output value.
Store the last valid output value.
The calculated output value is incorrect.
Set the fault behavior in the Discrete Input Function Block:
• Go to Output > Function Block: Discrete Input > Fail Safe Mode > Fail Safe Mode and
select one of the 3 options.
• Press Enter: the status field reads Changed
You can use SIMATIC PDM to determine the fault location by looking at the Input and Sensor
Values of the Transducer Block.
Simulation
Simulation functions are helpful when you are installing the transmitter.
• You can create process values without recording actual values.
• You can use the full range of values of the simulated process values.
• You can simulate errors.
The LCD displays Si in the Mode display when Simulation is activated.
Output simulation
Output simulation allows you to provide process values for the cyclic class 1 Master, to test
how the automation program processes those values.
Carry out the following settings:
1. Open the Device Menu Simulation.
2. Select the register Output.
3. Set the target mode to MAN (manual).

Description
The predefined preset safety value is output (sta-
tus code U_075).
The last valid output value is output (status code
U_071).
The bad output value is accompanied by the sta-
tus which the Transducer Block assigns to it
(B_0xx).
