Siemens Step 7 CPU to CPU by Communication via Profibus in Simatic Manager
Thanks you about video. Its very useful for me.
Excellent
Thank you very much
I want to make a temporary conclusion, that the communication goes through the exchange of data sent to a word memory variable (MWxx), both PLC nodes can read the word memory status, for example:
I0.1 on the master wants to turn on the Q0.1 output on the slave
The master must send a value to the memory word variable when the I0.1 state is on or off, and the slave can read the same memory word state then interpret its value in the slave.
masters
I0.1--->Mw100
slave Mw100 --- Q0.1
is that so?
I am not very clear what OB82 and OB121 mean, but I suspect that is where their data exchange is which is used together as a memory buffer.
is that so?🙏🙏
very well
welcome
thank you friend thank you

Thanks a lot for sharing this type of video on request.please also share cpu to cpu communication by ethernet.it is also necessary for us
I will share soon
Thanks a lot.please share more and more video tutorial for different use
I really would like to thank you for all your videos, I really appreciate too much & I hope really you continue to learn more from you because your way in explanation is easy & awsome, in this video I've made all your steps in Simatic S7v5.5 & simulate with PLCSIM but Unfortunately it didn't work however I tried so many times,,,,could you tell me the reason
I think It works with physical system .... not with PLCSIM.....
nice , formative content
please make video about communication via ethernet
Thank you
Sure bro .... but problem is I have only one S71200 CPU with me any way i will try
@@EASYPLCTRAINING i appreciate your reply
If you can do it just by simulator that will be helpfull
@@EASYPLCTRAINING bro you just hsow the software work by simulation in the plc sim or by showing the var table.also please try to establish the communication by programming get/put fb with description. so that it will more helpful to understand every step. thanks in advance
When i have established a communication between two cpu data is not transferring between cpu.when open ob1 shows a message block can nit be monitored because doesnt match what can be the reason.hardware setup os ok

Sir it would be also helpful if you show the communication process by programming get/put function.please try to do it in next video with profinet communication

Topppp
first I want to thank you for this great work.
but I have a question
In the master Cpu there be a SF . the red led was ON.
how did the program work?
you can see this in the end of the videos
Yes, correct .......... It was because I power OFF one CPU
Bro how i can communicate with Siemens Extension module ET200 (IM 153-1) . Please make a video on it.?
I have tried by myself to communicate two cpu by following your this video but the data is not transmitting from one cpu to other.what can be the reason please help
I've tried as well as you but also didn't work, however,I repeated many times,,,,I think the reason maybe this can work only with Physical system not using PLCSIM as I did,,,Maybe
Yes dear you are right .... I also tried with PLCSIM but not working ... I will try with PLCSIM advanced and see the results
@@EASYPLCTRAINING Will be waiting for your results ASAP,,,thanks for you really for your efforts
@@EASYPLCTRAINING Nadeem sb still waiting for your reply.
