Good day! i have CPU 315-2 DP (315-2AG10-0AB0)(firmware 2.0.8) and CP 343-1 (343-1EX11-0XE0)(firmware 2.3.5)

I connected this element to each other on rail and  configureted with MPI adapter (972-0CB20-0XA0) All configurated good, without errors. i create OB1 and wrote little program. All worked good. i can monitor my program.

Then i connected ethernet cable to CP and PG, change adapter to "my ethernet card" TCPIP in SET PG/PC interface. MPI adater is still connected. All works good. i can monitor my program. On CP i saw that RX/TX is flashing quickly. This means that the exchange goes through CP. 

But then i disconnected MPI adapter. i can ping CP, but i cant monitor program, write configuration to hardware and other works with CPU. Whats wrong? 

Hello dieego6;

Have you changed your setting in PG/PC interface from you programming device to be TCP/IP also?

I Think you may forget to change it as you lastly was using MPI connection protocol.

If your problem solved, Just let me know

No, i dont forgot change settings. In Set PG/PC interface i set my ethernet adapter TCP/IP. With MPI adapter all work, without dont.

 Hello Diego,

 have you already seen this:

 Good day! 

It was so similar to the solution, but it did not help

I create new project and configureted network like in instruction in youre link

1 image - in hardware i add cpu and cp

2 image - in netpro i add pg/pc and add ethernet interface with ip 192.168.0.2

3 image - i added mpi interface to pg/pc with address 5

4 image - Conneted pg and controller to ethernet and mpi in netpro

5 image - ip address of cp is 192.168.0.3, mpi address is 3

6 image - mpi address of controller is 2

7 image - Compile and save in net pro - no errors

Then i download hardware to CPU via mpi - no errors

Then i change connection to TCP/IP and try download hardware - no errors

Then i disconnected mpi connector

8-10 image - try download hardware to CPU and got error "Connection could not be established. The connection partner is not responding" "Unable to establish a connection to module CPU 315-2 DP (R0/S2)"

Whats wrong?

Hi,

On the ethernet hvere the CP is connected, is there anything else than the CP card and the PC you download with?

I can see that in you hw config that you set the CP card to 192.168.0.3, but in the download dialog, the browse of the network shows that the CP card still has ip 192.168.0.1.

It looks like the download to the cpu has not really taken effect?

Perhaps something else (a switch/router?) on the ethernet has an ip conflict or the download failed without you noticed it?

 Unfortunately, everything as I described

Hi Dieego,

If you're connecting peer to peer do you have crossover cable?

Hi Dieego,

If you're connecting peer to peer do you have crossover cable?

 Hello Yanto, thanks, I'll try in 1-2 days, crimping pliers now do not have me
