2.3 Differences between F-CPU 1510SP F-1 PN and standard
CPU 1510SP-1 PN
Areas of application
CPU 1510SP F-1 PN is mainly used for the protection of personnel and machinery and
burner controls. In addition to the safety program, you can also program standard
applications.
Table 2- 1 Areas of application
You intend to use CPU 1510SP F-1 PN for
Safety-related applications

< 2E-05
Restriction with "CREAT_DB" and "DELETE_DB"
F-DBs can neither be created nor deleted.
Restriction with "READ_DBL" and "WRIT_DBL"
The destination address must not point to an F-DB.
Restrictions when configuring the retentive behavior of data blocks
The configuration of the retentive behavior of data blocks is not supported for F-DBs.
This means that the actual values of the F-DBs will not be retentive in the event of Power
OFF/ON and Restart (STOP-RUN) of the F-CPU. The F-DBs retain the initial values from the
load memory.
The "Retain" check box is grayed-out for all tags in F-DBs.
