F parameters: F- -monitoring time
The F monitoring time defines the maximum time until a new valid F telegram must
have been received from the F master.
Note
If the F monitoring time is configured to be shorter than the PROFIsafe monitoring
clock cycle set using the appropriate machine data, when the control runs--up an
alarm is displayed:
Alarm 27242 "PROFIsafe: F module %1, %2 incorrect"
Parameters: DO/DI channel x
The channels of an F module are parameterized in the properties dialog box under:
Dialog: Properties
Tab: Parameter
Parameters > Module parameter > DO or DI channel x
F- -DI module
The channels of the F--DI module are mapped differently to the NCK/PLC--SPL
inputs $A_INSE/INSEP depending on the selected parameterization.
S 2v2 parameterization
For 2v2 parameterization, the process signals of both channels in the F--DI
module are combined to form one F useful (net) data signal and thus supply an
SPL input data.
Fig. 7-12
S 1v1 parameterization
For 1v1 parameterization, the process signals of both channels are transferred
from the F--DI module and can thus supply 2 different SPL input data.
