Hello ,
You will find the answer to all these questions in the manual for S7-F/FH system and the FAQ related in the SIOS.I select  randomly from your questions for a fast brainstorm :

6-To delete the content of Flash (Without pass),I think you need a PG .Just to be sure that you have the offline project to transfer later.

5-For an H application you are normally asked to select the target CPU and you select the master.

4-A piece of label to stick on the Flash and it shows the final valid signature of safety program in it.

I hope these short answers help,

Hello ashish;

For your point #1, the Copy program to memory card function is used in all S7-400 CPUs that use a EPROM memory card in order to save the program. For those that use a RAM card (or no card at all, using the small integrated RAM load memory of the CPU) then a simple Save is the way to go.

For your points 2 and 3 (which are linked), the Save Reference button function is described this way in the S7-400F/FH manual:

10.2.3 "Save Reference" button

You can save all data of a safety program (charts, parameters, etc.) as a reference to be used as necessary for comparisons.

So basically you can save the Safety program, and the Reference program, so that you can determine if the Safety program was changed since the last compilation, for example.

The attached screenshot (from the same manual) explains what kind of values are used for comparison in a Safety program.

Hope this helps,

Hello ashish;

Please follow instructions as detailed in the manual:

10.1 Compiling an S7 program 

Introduction

You compile a safety program in the usual way in the CFC Editor , that is, by  compiling the entire S7 program.

Procedure

If an S7 program contains a safety program, then the safety program is automatically compiled when the CFC charts are compiled. Fault control measures are automatically added, and additional safety-related checks are performed. 

10.6 Downloading the safety program

Introduction

After compiling, you can download the CFC program to the target system. You can  download the entire safety program or just the safety program changes, depending on whether safety mode is activated or deactivated

10.6.1 Downloading the S7 program

Procedure

To download the safety program to the target system, call the CPU > Download > Scope: Entire program menu command in the CFC Editor . The F-CPU goes to STOP mode.

Note

You are prompted to enter the password for the F-CPU prior to downloading the safety program if changes in the safety program are detected.

Working with safety programs on a memory card

WARNING

Safety program on a memory card

If you are using a safety program on a memory card, you must observe the following:

• Before switching the S7 F-System to RUN mode, compare the collective signature of the safety program on the Flash EPROM memory card to the collective signature of the reference data. If necessary, label the memory card with the collective signature.

• In the case of a fault-tolerant S7 FH System, make sure that the memory cards of the redundant F-CPUs are of the same type (RAM or Flash EPROM) and that the same safety program is located on redundant Flash EPROM memory cards.

• Ensure access protection against removal and insertion of memory cards.

Hope this helps,

Daniel Chartier
