Hello ammy and Grim 

I am also trying to communicate between two PLC using simulation. I programme is running but data is not getting transferred. In status some time I am getting 25. Can any body help me. If any one sample programme please share it with me.

Regards

Hi Grim Reaper,

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"

& all above Blocks are related to Ethernet only......

& Here you will find Which components are not supported by S7-PLCSIM V5.4 SP3?

------------------------------------------------------------------------------------------
Split from communication between 2 simulator modules.

I am also trying to communicate between two PLC using simulation using used urecv. But the data is not getting transferred.

Some time error comes with status 25 . Can any body help me. If anyone have programme for usend urecv in Ethernet for simulation please share it with me.

Hello Which PLCs do you use?

S7300/400 or S71200/1500??

Please look here perhaps it helps:
