Transferring The Safety Program To The F-Cpu Using A Memory Card - Siemens SIMATIC S7 Configuration And Programming Manual

1.2.17.2 Transferring the Safety Program to the F-CPU Using a Memory
Card
Use of MMC or Flash Card
The following safety note applies to use of the following:
•
Flash card (for example with CPU 416F-2)
•
MMC (for example with 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 using a memory card (MMC of Flash Card) to ensure that the F-CPU does
not contain an "old" safety program:
1. Turn off the power to the F-CPU and remove the battery of F-CPUs with battery
backup (for example with the CPU 416F-2). (To make sure that the F-CPU is
no longer powered, wait for the buffer time of the power supply you are using
or, if this is unknown, remove the F-CPU.)
2. Remove the memory card (MMC or Flash Card) containing the old safety
program from the F-CPU.
3. Insert the memory card (MMC or Flash Card) containing the new safety
program in the F-CPU.
4. Turn on the power to the F-CPU again and insert the battery of F-CPUs with
battery backup (for example with the CPU 416F-2).
You must make sure that the inserted memory card (MMC or Flash-Card) contains
the correct safety program. You can do so through a program identification or other
measures, such as a unique identifier on the memory card (MMC or Flash Card).
When downloading a safety program to a memory card (MMC or Flash Card),
you must use the following procedure:
1. Download the safety program to the memory card (MMC or Flash Card).
2. Run a program identification (in other words, check whether the collective
signatures of all F-blocks with the F-attribute in the off-line block container and
on the memory card (MMC or flash card) match, see manual, Section 5.10.2).
3. Label the memory card (MMC or Flash Card) accordingly.
The procedure outlined must be ensured through organizational measures.
