jedmal Posts: 5 Rating: (0)	Hello,I have a problem with communication between CPU313C-2DP (6ES7 313-6CE00-0A0) and CPU 315-2 DP (6ES7 315-2AG10-0AB0) using CP 343-1 Lean (6GK7 343-1CX00-0XE0) on both side.I heve to exchange information (one DB in each using AG_SEND and AG_RECV) between CPU313C-2DP and CPU 315-2 DP. When information is sending from 315-2 DP to CPU313C-2DP I can see changes almost immediately.The problem is when information is sendig from CPU313C-2DP to 315-2 DP. I can see new information after at least 10 seconds.The helpful information is that CPU313C-2DP also has communication with two S7-200 CPU using MPI.Waiting for any halp JEDMAL

J_Bell Posts: 5822 Rating: (412)	Dear Jedmal, I would wonder if you could check the following points. - How is the Communication if the MPI Bus is disconnected? - How long does it take to send PING in between the two CP’s? - Is the OB1 cycle time very different between the two systems? - How do you program the Send and Receive Function, do you evaluate the Status and Error / Done / NDR Bit? Just to begin with. Best regards J_Bell

Solutions: * Replace one CP343-1 Lean for a CP343-1 (not Lean), because this module can act as a client. * Try other communication protocolls like e.g. TCP/IP
