I ’m building three identical machines. These machines are each set up with Multi Panel MP270B Touch-10 TFT (6AV6545-0AG10-0AX0) , CPU 315-2 PN/DP (6ES7315-2EG10-0AB0 / V2.3) and a Scalance X005 ethernet switch. The X005 switches is connected to a higher level Scalance X-208 switch.

The problem is that only one of the multipanels is willing to talk through its X005 switch, the other two panels refuse. If I connect them to their switch, both lights on the ethernet interface lights up and stay on. If I exchanges on of the non working switches with the working one the problem don’t move, if I exchanges one of the non working panels with the working one the problem moves. So I think the problem lies in the panels. If I connect

the non working panels directly to my lab-top I can communicate with them through the Ethernet interface, so the interface have to be in order.

Serial numbers on the panels is:

C-TDF10017 working

C-TDF09977 not working

C-TDF10007 not working

Best regards

Geir
