Parameterization in a PROFIsafe system
Parameterization includes the following:
– Assigning the PROFIsafe address
– Parameterizing the inputs
– Specifying the F-Parameters and i-Parameters
PROFIsafe address
The PROFIsafe address is a unique ID for the Smart Element in the PROFIsafe network
topology. It is assigned in the configuration software.
Use the DIP switch on the Smart Element to set the address that you assigned earlier in the
configuration software.
See
“Setting the safety address” on page 26
Parameterization of the
inputs and clock outputs
The parameterization of the safe inputs determines the behavior of the Smart Element and
influences the safety integrity level that can be achieved.
The controller automatically writes the parameterization created in the parameterization tool
to the Smart Element on every power-up or reset.
The following conditions must be met:
– Supply voltage is present
– Local bus is in the RUN state
– Communication connection has been established between the controller and the
Smart Element
The Smart Element cannot be operated if it is not parameterized. The FS LED flashes.
The Smart Element is ready to operate if the parameters for all inputs are valid and transmit
-
ted without errors. Valid input data is only read in this state. In every other state, the safe
state is transmitted for each input (“0” in the process image of the inputs).
If errors are detected during parameterization, the parameterization data is not applied. The
flashing FS LED indicates that the parameterization is invalid. In addition, the error is
reported to the controller.
In this case, check and correct the settings.

“Errors: messages and removal” on page 67

Parameters
Assign the parameterizable F-Parameters and i-Parameters.
The communication address configured in the controller project must match the address
set on the Smart Element.
The settings on the Smart Element take effect after a power-up.
