 Hello, 
I haven't a large knowledge in siemens.

I don't find wich variables to replace "V" variables

Hello, 
I have 2 CPU the first one is S200 and the second is S1200, i would like to replace the s200 with the S1200 but when i change the type of CPU in the TIA Portal program i have some errors in some variable "V".
which new variable in S1200 that replace "V" in the S200 program

What is the highest number used with V-memory?
Does your S7-200 have any M-memory?

You can use M-memory. The S7-1200 has many more M-bits.
Use the formula:

number of V-memory + 1000 -> M-memory

Example:

S7-200    S7-1200

V300.7     M1300.7
VB1230     MB2260
VD2000     MD3000

Read the documents that @gc137 suggested. It will help you in the long term.

 Hello,

In the add attachment, you can see the Variable "V" in which i have problem only in this ones 

Thank you

V is the adress of the variable in the S7-200 !

So you must now enter the adress you configured for this variabel in the S7-1200.

Opent the symboltable of the S7-1200 and show which adress have the symbol on the S7-1200 PLC, then enter this adress in the HMI.

Hi,

install V11 , Upload the program from PLC, convert it to V13.

Hi,

https://support.industry.siemens.com/cs/ww/en/view/106449434

Download = Loading from PC to the PLC

Upload = Loading from PLC to PC

An Upload of the V11 blocks from the PLC Target to engineerin system TIA V13 is no possible.

Regards

Christoph
