  • Page 5: Ethernet Networking

    Ethernet Networking Overview The 6K is equipped for Ethernet communication. It includes 10Base-T (10Mbps twisted pair); TCP/IP protocol. RJ-45 connector. Default IP address is 192.168.10.30. You have these options for networking the 6K over Ethernet: • 6K as a client. You can connect the 6K via Ethernet to multiple devices, creating a client/server network.
  • Page 6 • 6K as a server. The 6K waits for a PC to establish a connection with it and then provides information on a continual or requested basis. The PC communicates with the 6K using the COM6SRVR Communications Server, which is also what Motion Planner uses to communicate with the 6K (for details, refer to the COM6SRVR Communications Server Programmer’s Reference).

  • Page 7: Networking Guidelines

    • Peer-to-peer network with other 6K or Gem6K units. The 6K may be connected to other 6K devices (6K Controllers or Gem6K drive/controllers) via Ethernet. Up to eight Setup Wizard Available 6K devices may be networked in this manner. This type of connection uses UDP The Motion Planner broadcasting and is not a client/server relationship.
  • Page 8 • If the 6K is placed on an open network, put the 6K and any associated server devices on one side of an Ethernet network switch with its own subnet and install a bridge to filter traffic, such that broadcast traffic does not pass in either direction (see diagram below).

  • Page 9: Configuring The 6K For Ethernet Communication

    Configuring the 6K for Ethernet Communication There are three major steps in setting up Ethernet communication between a PC and controller: • Step 1 prepares the 6K for Ethernet communication, and must be performed using RS-232 communication. • Step 2 sets the TCP/IP properties on your PC to allow Ethernet communication, and statically maps the 6K’s MAC address to the IP address of the Ethernet card in your PC.
  • Page 10 If you are using Windows NT, select the “Protocols” tab. Make sure this number is different from the one in the 6K’s IP address. If the 6K’s default IP address is unchanged (192.168.10.30), then select a number other than 30. NOTE If you are using a computer (Ethernet card) that is normally connected to a network, you should write...

  • Page 12: Networking With Other 6K Or Gem6K Products (Peer-To-Peer)

    Networking with Other 6K or Gem6K Products (Peer-to-Peer) You can communicate information between 6Ks and Gem6Ks over Ethernet. This feature uses UDP broadcasting over the subnet to transfer data, so no client/server connection is needed. Up to 8 different 6K or Gem6K devices can share information, with each device having access to shared data from the 7 other devices.
