Hi,

Hi,

you can add a secon IP on the networkcard in the range 192.168.0.x this should be work.

Regards

Christoph

 How can a second IP (with a different subnet) be added to the networkcard ?

I looked in the network card properties (V13 SP1, upd 9) but the 'change settings' button is disabled (greyed out). I'am logged in as administrator and started Tia by right clicking 'run as administrator'. My IP configuration is fixed (not DHCP).

(Why is a second IP necessary when a router is configured between the two subnets ?) 

Searching accessible devices only shows PLC's in the current subnet.

Normal and Extended download failed to make a connection to the IP in the other subnet.

Ping to that IP-address answers just fine

Are there other ports except for TCP 102 that should be kept open by firewalls ?

Thanks for a reply.

Kurt

Split from Access PLC on different subnet in local network.

Change the subnet mask from 255.255.255.0 to 255.255.0.0 on both subnetworks that way everything is in the same network, but is this really the best solution?

with 255.255.255.0 only 1-254 is the range of devices

with 255.255.0.0 the range is from 000.001 to 254.254 and there is no network with the 3 part used!

Hello Kurt

The Search of accessible devices will always work only in the same subnet because it works with MAC Adress broadcasts and this works on a lower OSI Layer than the IP Protocol. SO you will not find any Devicec outside the subnet. If you want you have to change your IP or use a second Networkcard (for example with USB-> Ethernet)

 or use a gateway with the option to send and recieve the needed broadcasts to both ends. That is why I suggested the subnet mask 255.255.0.0
