Hi

Could you tell me how can I Hold the Process Such as Timers and Values in memory In S7/S300?

Thank you all

Hi,

here are some FAQs about your questions:

How can you back up the actual values of DBs and markers?

and

Retentivity behavior of S7-300 CPU 31x and complete devices C7-6xx with MMC

But one more question

Is it possible To simulate the retentivity of timers in PLC simulation?

Hi again,

I think you can´t simulate this. There is also a FAQ about differences between Simulation and real CPU:

Hope this helps!
