Display of the process data word (PZD) The currently set start address for the
Length of the telegram in bytes or words. The telegram length depends on the
telegram type used.
Display of the extension of the relevant telegram in words or setting, if supported by
the telegram type.
The use of various consistency areas is useful to optimize the performance of an
S7-CPU. Consistency areas that are longer than two words must be edited with
system functions. You can use the effective Load/Transfer commands for consis‐
tency 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.
Display of the process image (partition), which is used to consistently transfer the
data.
Specification of the interrupt OB number for the output of diagnostic information.
If this option is activated, you have the capability of assigning the F-monitoring time
manually. Otherwise the F-monitoring time will be assigned according to the global
parameterization at the interface (DP interface > F-parameters).
Monitoring time in the fail-safe DP standard slave/IO standard device/PA field de‐
vice.
A valid, current safety telegram must arrive from the F-CPU within the monitoring
time. This ensures that failures and errors are detected and the appropriate reac‐
tions triggered to keep the safety system in a safe state or to transfer it to a safe
state.
If this option is activated, you have the capability of assigning the F-I/O DB-number
manually. Otherwise it is assigned by the F system.
Controller
configured module that you can accept
or change.
If you change the start address for a set‐
point value, the start address is also
adapted for the actual value.
Only PROFIsafe: The start address is
part of the F-I/O DB-name of this tele‐
gram. If you change the start address,
the F-I/O DB-number will also be
changed.
