Hi ,

Trial taken with CPU S-317 PN/DP with router connected and through internet , I can go online to PLC.

But when same router is connected to another PLC S7-416-2 DP , connected to Scalance X108 through CP443-1 card , I can ping to router but PLC is not reachable ,

If I connect CPU S-317 to same Scalance then I can go online to PLC ,

can anybody suggest , what kind of setting need to modify in CP443 or S7-416 system , so that through router I can go online .

Check the IP address it should be for S7-300 192.168.0.1 and S7-400 192.168.0.2 for example 

Hi,

I think your Router blocks data. Port 102 ist blocked by default i.E. and must be enabled for complete transfer route.

Please have a look to FAQ:

Which ports are used by the various services for data transfer by means of TCP and UDP and what should you watch out for when using routers and firewalls?
