-CP 343-1 Lean: 6GK7 343-1CX10-0XE0
-S7-1214C: 6ES7 214-1HG40-0XB0
-CM 1243-5: 6GK7 243-5DX30-0XE0
Used Software:
-SIEMENS TIA Portal V15.1

thanks for uploading. many many thanks
good video
Thank you for your sharing. But I have a question, when I connect 2 PLCs to each other in 'devices & networks' and set up the 'Transfer area' in 'I-slave communication' (Ex: Master address : Q10, Slave address I10, master send data to slave) . To send data from Master (Q10) to Slave (I10), what i need to do is 'move data' to Q10 in main block of Master, and Slave (I10) will receive data automatically, right? I am a beginner, so hope you reply.
Yes, that’s right. Please take a look at this video: TIA Portal: IM151-7 CPU as I Slave for 1500/1200/400/300

@@automatikavaldymas Thank you!
Dear, it is possible to simulate this example of communication.
Unfortunately it is not possible. But you can simulate TCP connection.
Thank you very much
I have 9 CPU's slaves and one CPU master connecting with others by profibus (all of that's are S7-1511-PN with profibus module)
I put transfer area and using move instructions , is it enough ? or I must use GET/PUT instructions??
Yes, that is enough. What you need to do is to set operating mode of the communication module - "DP slave", because by default it is "DP master".
@@automatikavaldymas So Put and Get instructions just for profinet not for profibus , Right?
Yes, PUT/GET is for PROFINET.
@@automatikavaldymas thanks alot🙏🙏🙏
Thank you!
Tell me please, is it possible to connect to the S7-1200 as a slave not a S-300 CPU, but an IM-153 module (for connecting S7300 DI/DO modules to S7 1200)?
Yes, you should be able to assign ET200M IM153 as slave for S7-1200. At least i can compile the project without errors. I will check if i have this module tomorrow, and if so, i will be able to test irl.
@alekseyalexej9665 unfortunately i have no IM153, so i cannot test it irl, but like i wrote in my previous post, you should be able to assign ET200M IM153 as slave for S7-1200. One thing you should take into account, that it might be so, that not all modules will be compatible with S7-1200 system.
@@automatikavaldymas Thank you, everything worked out already. So far only in hardware configuration S7-1200. The principle is the same as in the case of two PLCs.
@@automatikavaldymas Interesting. I also tried the same and was able to compile it. When I went forward to place the order, Siemens told us they havn't tested this so they can not gaurantee the system will communicate. Then we went for another PLC
