Simatic S7-300

Dear all, 

I have one basic question about CPU. In attachment I will post picture, Is this X presenting number 2?

Does it matter which number is written in that corner? And if it does.. is it about the speed of the CPU?

Or for example if I have CPU with number 1 in corner, are my possibilities limited so I can't use some OB's, SFC's etc. which are allowed to CPU with that number 9? Or am I wrong?

If someone can explain me what that number in corner means I would be very grateful.. 

Im talking about same CPU with 2 different numbers.. 

With best regards, 

Marko

 Hello Markozg,

The X is the hardware version (E-stand) have a look:

Is for panel but is the same:

How can you determine the "E-Stand" (hardware release) of an operator panel?

Dear Ste39,

Thank you for your feedback,

Can you explain me diference between hardware E-Stand 01, and 09 ? 

Thank you so much

 Dear marko,

In "poor word" the 01 is the first version and the 09 is the most recent 

you can say "improvements Hardware"

Hi,

or improvements Software

The E-Stand is also incremented with a new FW Version

 Dear Marko,

 As an example a Input card with E-Stand 01 , maybe if there is a defect, Siemens improving it and goes to an E-Stand 02 this is for CPU with improving Hardware and Firmware also as said our friend Christoph

Dear all,

Just one question.. By improving SW and FW am I able to use some new blocks which were unavaible in previous version? 

New blocks like some new OB's, SFC's etc.....

That are some general improvements made by Siemens, but I can't find on Internet which the improvements were made.. 

Im interested in this, please help 

Thank you in advance,

With best regards,

 Hello Marko,

More than CPUs are improved and more have development opportunities.

Give  us a code like CPU 6ES7 31x-xxxxx-xxxx

Hello,

you can look in the delivery notes of the FW Versions if new blocks are released with the FW, normaly no change on the SFC is made.

OB, FB, FC ist usercode and not from siemens!

Hw changes not documented for users!

Regards

Christoph
