Ethernet Motor Communication Recommendations

• The Ethernet track topology for the motors that use Ethernet for communication is
defined in a MagneMotion Information and Configuration Service file (see
Motor MICS File on page
• Recommended Ethernet addressing scheme (see
Network.Path.Motor
• Network addresses are used for network configuration.
• Path 0 addresses are used for Subnet configuration:
Where:
• Path p addresses are used for motors on that path:
Where:
• Switches are two logical track paths, only one IP address is assigned.
• Maximum number of motors per Ethernet chain = 50.
• The two Ethernet ports on the motors are not DLR enabled.
• Factory network design must minimize extra traffic on the physical network that the
transport system is using.
• Only use linear (chain) or star Ethernet connection topologies (see
through
• When using a linear topology, if any device becomes disconnected, all devices
downstream of that device lose communication.
• Closed-loop (ring) Ethernet connections must be avoided (industry standard
Ethernet practice) to help prevent network saturation.
• Only pass transport system communication through the Ethernet chains in the
transport system.
• Large amounts of traffic can degrade the performance of the transport system.
• Standard IP UDP communication, low latency.
• 100BASE-TX Fast Ethernet (IEEE 802.3u) compliant.
• Minimum of Cat 5 cabling is required.
• Ethernet communication topology is independent of transport system configuration
(Ethernet chaining does not have to follow the physical path layout).
