10-9. Network Checklist For Axcess E
A. General Network Information
There are two 10/100 Ethernet NICs (Network Interface Connections) on the Axcess E. Either port can be used for any purpose. We generally use Port
A for direct connections and Port B for network connections. For flexibility, from the factory Port A is set with a static IP address and port B with a
dynamic (DHCP) address. Port A may often be connected to a PC for initial configuration, to a robot with an EtherNet/IP connection, or to a robot
through an ADAM block for discrete Inputs/Outputs. Sometimes Centerpoint on a PC is directly connected to Port A, and Port B is used for remote
configuration over a factory network if there is no robot.
The simplest connection is to use the factory default connection of the Axcess E, Ethernet port A, connected directly to a computer for configuration.
The factory default address for Port A is 169.254.0.2. This is in the IP address range of a PC when directly connecting to the welder (no DHCP server,
will take about 1 minute after connection for Windows XP). (See http://www.ietf.org/rfc/frc3927.txt, Link Local Address selection.)
Miller Electric Mfg. Co. supplies Industrial Ethernet cables for use with the Axcess E. These are available in 3, 5 and 10 meter lengths and have a
shielded RJ-45 connection to connect to a PC or network drop. Shielded CAT-5 cable is strongly recommended in the welding environment, and proper
termination of the shield is important for noise-free operation.
The Centerpoint program will run on almost any PC compatible computer. It can handle weld monitoring functions from several Axcess E machines,
depending on the speed and configuration of the network. Some customers choose to associate one PC or PC-HMI with each Axcess E and operator
and Centerpoint.
B. Network Scenarios
S Axcess E semiautomatic with PC or PC-HMI in the cell:
This requires only a direct connection between the Axcess E and the PC device running Centerpoint. A cable of the appropriate length can be connec-
ted between Axcess E Port A and the PC device. The other port of the Axcess E can be connected to a factory intranet for configuration and diagnosis
via web pages.
S Axcess E semiautomatic with multiple welders per PC device:
This configuration will require an Ethernet 10/100 capable switch, and cables between each Axcess E and the switch. The PC device will also plug into
the switch. If the switch is also connected to a company intranet, the welders web pages can be viewed from other PC devices on the network. IP
addresses can be set before connecting the welders to the switch if static addresses are used. If DHCP on an intranet is used, connect the welders
Port B, or use the web pages to set up the Ethernet before connecting together. If the factory intranet has a lot of broadcast traffic or there are 10 or more
Axcess E machines on one switch, it is recommended that the switch not be connected to the intranet to prevent excess network loading.
S Auto Axcess E analog or Devicenet connected to a robot with PC or PC-HMI in the cell:
A direct connection is needed for the ADAM block which provides part and weld information to Insight and Centerpoint. This is normally done with a
cable on Port A to the ADAM block. Port B would then be used to connect Centerpoint to the welder. This could be through a network connected switch,
in which case no setup is needed (DHCP) or a direct connection by assigning a fixed address to Port B.
S Auto Axcess E analog or Devicenet connected to a robot with multiple welders per PC device:
A direct connection is needed for the ADAM block which provides part and weld information to Insight and Centerpoint. This is normally done with a
cable on Port A to the ADAM block. Port B would then be used to connect Centerpoint to the welders. This could most easily be through a network
connected switch, in which case no setup is needed (DHCP) or fixed addresses could be assigned to the welders connected to the switch.
S Auto Axcess E digital connected to a robot with PC or PC-HMI in the cell:
A direct connection is needed for the robot which commands the welder and which provides part and weld information to Insight and Centerpoint. This is
normally done with a cable on Port A to the robot. Port B would then be used to connect Centerpoint to the welder. This could be through a network
connected switch, in which case no setup is needed (DHCP) or a direct connection by assigning a fixed address to Port B.

S Auto Axcess E digital connected to a robot with multiple welders per robot and per PC device:
Direct connection is needed for the robot which commands the welders and which provides part and weld information to Insight and Centerpoint. This is
normally done with a cable on Port A to the robot, and in this case possibly a switch in the robot controller to connect the multiple welders. Port B would
then be used to connect Centerpoint to the welders. This could most easily be through a separate network connected switch, in which case no setup is
needed (DHCP) or fixed addresses could be assigned to the welders connected to the other switch. If EtherNet/IP traffic and Centerpoint traffic are
mixed on the same switch, careful measurements of available bandwidth and latency will need to be performed at installation.
