1.2.16 Compiling the Safety Program
Note
Before you compile the safety program, close the LAD/STL/FBD editor, Display
S7 Reference Data, and Check Block Consistency applications.
1.2.17 Complete Function Test of Safety Program or Protection through
Program Identification
Introduction
The following two sections replace the corresponding sections in the Section 5.8.5
of the manual.
1.2.17.1 Transferring the Safety Program to the F-CPU with a
Programming Device/PC
F-CPUs with an Inserted Memory Card (Flash Card or MMC)
The following safety notes applicable when the safety program is transferred from a
programming device/PC to:
F-CPUs with a flash card inserted (for example CPU 416F-2) •
• F-CPUs with MMC
(for example CPU 317F-2 DP, CPU 315F-2 DP or IM 151-7 F-CPU)
!
Safety Note
If the function of the safety program is not tested in the target F-CPU, you must
comply with the following procedure when transferring the safety program to the
F-CPU with a programming device/PC to ensure that the F-CPU does not contain
an "old" safety program:
1. For F-CPUs with MMC: Download the safety program to the F-CPU in the
"Safety Program" dialog.
For F-CPUs with flash card inserted: Download the safety program to the
F-CPU in the "Download User Program to Memory Card" dialog.
2. Perform a program identification (that is, check to determine whether the
collective signatures of all F-blocks with an F-attribute in the block container
match online and off-line; refer Sections 5.8.4 and 5.10.2 of the manual).
3. Perform a general reset of the F-CPU using the mode selector or by means of
the programming device/PC. After deleting the work memory, the safety
program is transferred from load memory (memory card, MMC on
F-CPUs 3xxF and IM 151-7 F-CPU or flash card on F-CPUs 4xxF) to work
memory.
