Hello,

Is it possible to make hot swap of modules in any S7 system? I always turn off 300 modules before setting any new one and then while insertin HW config it goes stp again. If I am right that is the same procedure with s7-400. Dont you think it sholud be possible to make it all on-line? Is it going to be possible to make so with s7-1200?

best regards

Yes it is.
Hot swapping (replacing module online) is available in S7-400 CPU whether you work with central modules (S7-400) or S7-300 modules (Profibus & Profinet).

With S7-300 CPU, it's available but just with Profinet.
Or maybe you can use the trick mentioned here

If I/O modules (in the ET200M) are inserted or removed during operation, then OB83 is called. But this OB is not supported by the CPUs of the S7-300 series, because it is not available in the CPU operating system. If the ET200M is configured as standard slave in STEP7 (via the GSD file), then Insert/Remove is possible, because in this case it is not OB83 but OB82 that is called. This OB is supported by all S7-300/400 CPUs


Best regards.

I don't know much about hotswap possibillities

But I just worked with a new type S7 CPU

6ES7 315-2EH14 V3.2.3


This CPU has Profinet IO

If you look at the online Technical data it is possible to use OB83 (only for Profinet IO )

Technical data new 315 PN DP

Hi!

Hotswap theoretical possible - if CPU has OB83. Then should see details.
 
As sample for  CPU I 6ES7 315-2EH14 V3.2.3 see in technical data
possible to use OB83 only for Profinet IO . This is due to the fact that when inserting / removing a module called OB83, and your the program can correctly handle of the change configuration

If I understand Your posts I see it is not possible to make simple module swap. There is another problem if you want to change module with different order number. Ex. DI16 change to DI32. You still have to update firmaware and this operation is not allowed in RUN state.

you can swap, add and/or reconfigure in RUN with CIR (Configuration in Run) dear Oscar_83PL and you'll find all the relevant info (what hardware is supported/needed, what is possible and what isn't) in the manuals and links below:
SIMATIC STEP7 V5.5 Modifying the System during Operation via CiR manual
Which DP slaves can be added to and removed from a PROFIBUS DP master system using the CiR function (Configuration in RUN) and which configuration changes are permissible?
What should you watch out for when adding components or changing their parameters using CiR (Configuration in Run)?
What should you watch out for when using the "Configuration in Run" (CiR) function on the PROFINET IO system?

Cheers

Hello!

I believe that CiR  is only available for CPU4xx or am I wrong?

Hello gre_m,

No, you are not.
The CIR is only available with S7-400 CPUs.

Best regards.

Hello
I understand your reply.  I wanted to say "The CIR is only available with S7-400 CPUs". May be defect translate.
