dear experts

i have 3 PLC's 315-2dp in that all DP are has been used already now i need to communicate Between them with Global Data communication by using Existing MPI

Is it possible to simulate the GD data in PLC SIM5.4 sp5


Thanks in Advance

thanks for the reply


Options for communications via MPI


i had gone through the above mentioned Link

Please let me know whether

• S7 basic communication
• S7 communication
  

these above connections are possible to do communication with PLC sim5.4 sp5 update2

As from S7-PLCSIM V5.4 + SP3 you can use S7-PLCSIM to simulate multiple CPU modules simultaneously in a STEP 7 project and establish communication between the CPU modules. The following communication blocks are supported for communication:

• SFB8 "USEND"
• SFB9 "URCV"
• SFB12 "BSEND"
• SFB13 "BRCV"
• SFB15 "PUT"
• SFB14 "GET"
• SFB19 "START"
• SFB 20 "STOP"
• SFB 22 "STATUS"
• SFB 23 "USTATUS"

Hi expert


Thanks for the reply

What if i am using Profibus for tempruary for simulation whether we can able to achieve communication between CPU using PLC SIM


Thanks in advance

I have used communication between 2 CPUs (S7 300) with 2 CP suitable for PROFIBUS (CP342-5 I don't remember the order number) , selected the type as S7 communication and SFB14/SFB15.It worked for me as test purpose.You can try.If I find some time around, I will re-create the test and upload here.

Hello,

Simulation of Global Data Communication is not possible with PLCSIM.

In the following FAQs, it is mentioned which functions that could be simulating using PLCSIM.

How do you simulate communication between two CPU modules?

Which components are not supported by S7-PLCSIM V5.4 SP4?

Hope this helps.

As Ayman said, Global Data communication is not possible with PLCSIM.But as I mentioned before, S7 connection via MPI can be done.See the result in the attachmnet and the source project that I will upload soon.
