Hello guys,

I would like to develop the safety part and control process on a safety PLC. Does this comply with the safety standard? Can you help me?

Thank you very much.

Hello David;

I hope I understand your question adequately.

If you have a Safety F-CPU, along with F-IO modules and a Safety program extension (such as Dustributed Safety, for example) then you can program the safety-related portions of your process.

But with the same F-CPU, using standard I/O modules  you can program the non-safety part if your process. The Safety program is compiled separately from the standard program  thee are even strict rules regulating register exchanges between the two programs (on the same F-CPU).

Have a look at this Safety engineering and programming manual for Siemens S7 CPUs, you should find a lot of  interesting information there:

Hope this helps,

Hello

DChertier thank you for your answer. 

I´d like to do the next. 

In a plc safety:

1º- In the Safety ob program part safety with io safety

2º- In the ob1 program process control.

My objetive is sale alone plc.

The question is this is possible, We had done something similar, We could attached manual, examples of layaut.

Thank you so much.  

Hello David;

The case you are discussing is already discussed in the manual I suggested earlier:

You will also find on SIOS a large number of application examples on Safety Programming  such as this one. Simply use the search box at the top right of this page to search for samples on F-CPUs, on Safety programs  or more specifically on the Safety CPU you plan to use in your project; filter the results on Knowledge base/ application examples, for starters.
