5.4 Explanation of the module/channel parameters
PROFIsafe addresses have to be unique for the station
• Station-wide uniqueness:
• Cross-station uniqueness:
• Verification following a change:
For Ethernet subnets and mixed configurations of PROFIBUS and Ethernet subnets, the
following also applies:
The combination of F-source address and F-destination address of all F-I/O modules only has to
be unique throughout the Ethernet subnet including all lower-level PROFIBUS subnets, under
the exclusion of cyclic PROFINET IO communication between Ethernet subnets.

5.4.3
F_monitoring time (ms)
Definition
You use this parameter to set the monitoring time for safety-related communication between
the F-CPU and F-I/O (PROFIsafe monitoring time) for safety mode.
The parameter is assigned a default value, but you can change it.
The configured F-monitoring time influences the response time of the system to a system error.
For this reason, the selected time must be as short as possible, but still long enough to prevent
timeouts in error-free conditions.
5.4.4
Number HART message frame repetitions
Definition
Specifies the number of HART message frame repetitions. If the I/O module receives no response
or a response with errors to a HART message frame sent to the field device, the message frame
is repeated, i.e. sent to the field device again.

WARNING
Fail-safe I/O modules of the ET 200SP HA are uniquely addressed station-wide by a
combination of F-source address (PROFIsafe start address of the assigned F-CPU) and F-
destination address. The F-system itself ensures that the F-destination addresses of all F-I/O
modules within the assigned F-CPU are unique.
To guarantee uniqueness across stations, you must verify that the PROFIsafe addresses
("F_source_address" + "F_destination_address") of the F-I/O modules are unique across
stations.
Because the F-source address "F_source_address" of the PROFIsafe address of the F-CPU is
automatically set to "1", you can only change the preset address "F_destination_address" for
F-I/O modules of the ET 200SP HA.
Note that the PROFIsafe address of the F-I/O module must be unique across all stations!
