Slot Slot in the device
Start address Display of the process data word (PZD)
Length Length of the telegram in bytes or words. The telegram length depends on the telegram type used.
Extension Display of the extension of the relevant telegram in words or setting, if supported by the telegram
type.
Consistency The use of various consistency areas is useful to optimize the performance of an S7-CPU. Con-
sistency areas that are longer than two words must be edited with system functions. You can use
the effective Load/Transfer commands for consistency areas up to two words.
Total length:
The consistency applies for all data of this slot. This default entry should usually be sufficient.
Unit:
The consistency applies for one process data word.
You must configure at least a "2" word "Total length" for the transfer of a double word.
Process image Display of the process image (partition), which is used to consistently transfer the data.
Interrupt OB number Specification of the interrupt OB number for the output of diagnostic information.
Manual assignment If this option is activated, you have the capability of assigning the F-monitoring time manually. Oth-
of the F-Watchdog erwise the F-monitoring time will be assigned according to the global parameterization at the inter-
time face (DP interface > F-parameters).

F-monitoring time Monitoring time in the fail-safe DP standard slave/IO standard device/PA field device.
(only PROFIsafe) A valid, current safety telegram must arrive from the F-CPU within the monitoring time. This en-
sures that failures and errors are detected and the appropriate reactions triggered to keep the safe-
ty system in a safe state or to transfer it to a safe state.
Manual assignment If this option is activated, you have the capability of assigning the F-I/O DB-number manually.

Currently set start address for the configured
module. You can accept or change the ad-
dress.
If you change the start address for an actual
value, the start address is also adapted for
the setpoint.
Only PROFIsafe: The start address is part of
the F-I/O DB-name of this telegram. If you
change the start address, the F-I/O DB-
number will also be changed.
