Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

20 Manual, 01/2016, A5E03858068-AA
4.2
Explanation of parameters
4.2.1
F-parameters
You must assign the PROFIsafe address (F-destination address together with F-source
address) to the F-module before you put it into operation.
●You define the F-source address using the "Basis for PROFIsafe addresses" parameter
in the F-CPU.
●An F-destination address unique throughout the CPU is automatically assigned for each
F-module. You can manually change the F-destination addresses set in the hardware
configuration.
You can find information on F-parameters for the F-monitoring time, the PROFIsafe address
assignment (F-source address, F-destination address) and the F I/O DB in the manual
SIMATIC Safety - Configuring and Programming
(http://support.automation.siemens.com/WW/view/en/54110126).
4.2.1.1
Behavior after channel fault
This parameter is used to specify whether the entire F-module is passivated or just the faulty
channel(s) in the event of channel faults:
●"Passivate the entire module"
●"Passivate channel"
4.2.1.2
Reintegration after channel fault
Use this parameter to select how the channels of the fail-safe module are reintegrated after a
fault.
Use in S7-300/400 F-CPUs
This parameter is always set to "Adjustable" when you use the fail-safe module in
S7-300/400 F-CPUs.
You make the required setting in the F-I/O DB of the fail-safe module.
Use in S7-1500 F-CPUs
When using the fail-safe module in S7-1500 F-CPUs, you set this parameter in the STEP 7
dialog of the fail-safe module:
●"Adjustable"
●"All channels automatically"
●"All channels manually"
If you have set the "Behavior after channel fault" parameter to "Passivate channel", you
enable individual setting of the reintegration type per channel with the parameter assignment
"Adjustable". The reintegration type of the respective channel is specified with the "Channel
failure acknowledge" channel parameter.
If you have set the "Behavior after channel fault" parameter to "Passivate the entire module",
you can only select the same reintegration type for all channels.
