Hello,

you can install a CP343-1 in the Rack of the PLC and integrate this CP in the Subnet of the Server.

Or you install a external Router / Gateway between the subnets like SCALANCE x-400.

Hello,

this message appears because the specified Subnetmask and IP Adress is "Classless" .
Thismeans that you use a CLASS A Subnetmask with a CLASS C IP Adress so the range of the Subnet is leaving the Ethewrnet Class.

This is normaly no problem if all components support this configuration.

Hello as already discussed you can use CP-343-1 fopr connecting PLC to another subnet,

you can also use PN-PN Coupler gateways to do so, such gateways help you to connect you with another subnet,

you can use gateways like 6ES7158-3AD01-0XA0.

as per you message info it is only for your information so that you can add your device to such subnet.

ethernet class is for maximum number ip addresses/ devices on that subnet likewise.

in your case you cxan neglect that message & go ahead .

 Hi,

in this topic you can't use a PN/PN Coupler because he need access from a engineering Station to the PLC and this is not possible with a couple.
A coupler can be used if you exchange I/O Data between 2 PROFINET Subnetworks, but not for a Engineering!
