Parker Hannifin GEM6K - Manual (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).

• Use a switch (recommended) or hub if you are making more than one Ethernet
connection with the 6K.
• The 6K client must have the same subnet address as all of the server devices it will
connect to (PLC, OPTO22, DVT, etc.). For example, if the subnet mask ( NTMASK ) is
255.255.255.0, and the subnet address is 192.168.10.*, then all devices (including the
6K) must have an address starting with 192.168.10.*, where the * number is unique to
the device.
• Fieldbus (DeviceNet or Profibus) versions of the 6K (part numbers 6Kn-DN or
6Kn-PB) cannot also communicate as an Ethernet Client at the same time.
If you have a Fieldbus unit and need to use Ethernet instead, execute the OPTENØ
command, then the RESET command (this disables the Fieldbus features), and then the
NTFEN1 or NTFEN2 command.
To re-enable Fieldbus communication, execute the NTFENØ command, then the RESET
command (this disables Ethernet communication), and then the OPTEN1 command.
• You cannot communicate to the 6K with simultaneous transmissions over both the
“ETHERNET” and “RS-232” (PORT1) connections.
• Follow the manufacturer’s setup procedure for each Allen-Bradley PLC, DVT camera
and OPTO22 Ethernet I/O rack.
• You should be able to ping every 6K, DVT camera, PLC and OPTO22 I/O rack from
the PC. Use the ping command at the DOS prompt:
ping 192.168.10.30
Device’s IP Address
(space)
If your PC responds with “Request Timed Out”,
check your Ethernet wiring and IP address setting.
• The following Ethernet setup commands need only be sent once to the 6K because they
are saved in non-volatile memory and are remembered on power-up and RESET : NTID ,
NTIO , NTIP , NTMPRB , NTMPRI , NTMPWB , and NTMPWI .
• If a PC is connected to the 6K/Device Ethernet network, then the PC should include all
devices in a static mapping table. The static mapping procedure, for the 6K’s address, is
found on page
6 .
• If the 6K is in a peer-to-peer network, enable Ethernet communication with the
NTFEN1
command ( NTFEN2 mode is not compatible with peer-to-peer communication).
