  • Multiple DL PLCs via a single wireless router?

    I have a setup with a wireless router with a static IP that I wish to use to connect to two different PLCs. I gave each a separate static internal node and port-forwarded to 7070 on PLC1 and 7071 on PLC2. I could connect to each inside of the router (of course), but could only connect to PLC1 from outside using the static IP. I tried setting several different parameters, but could not see PLC2 from outside. Any suggestions on how to set this up?

    I know I should probably setup a VPN, but I don't have any experience in setting up that.

    Thanks,

    A VPN is pretty much the only way to do it with both PLC's having the same fixed port number.

      Is there a way to change (assign) specific port numbers on the PLCs and use port-forwarding on the router?

        Not for DirectLogic. In Do-more you can assign a secondary port in the System Configuration.

          It is possible to do with port forwarding, but you need to modify the DS600.ini file.

          Under the [devether.dll] category, uncomment or add
          Code:
          UDPPortNumEnable=1
          Once done, when you configure the Advanced options on a link, you can specify a target port. Then, configure port forwarding in the router:

          for PLC 1: [Public IP] port 7070 UDP to [PLC 1 IP] port 28784
          for PLC 2: [Public IP] port 7071 UDP to [PLC 2 IP] port 28784

            I had forgotten about that. Thanks!
