Configuration Recommendations
• Recommended Ethernet addressing scheme (see Figure 3-1):
Network.Path.Motor
• Network addresses are used for network configuration.
• Path 0 addresses are used for Subnet configuration:
x.y.0.m
Where:
m – Node controllers/Network devices
• Path p addresses are used for motors on that path:
x.y.p.m
Where:
p – path
m – motor
Figure 3-1: Ethernet Motor Wiring Example
• Switches are two logical track paths, only one IP address is assigned.
• Maximum number of motors per Ethernet chain = 50.
• Factory network design must minimize extra traffic on the physical network that the
transport system is using.
• Only use Chain or Star Ethernet connection topologies.
• Closed-loop (ring) Ethernet connections must be avoided (industry standard
Ethernet practice) to help prevent network saturation.
• Large amounts of traffic can degrade the performance of the transport system.
Only pass transport system communication through the Ethernet chains in the
transport system.
• Standard IP UDP communication, low latency.
• 100BASE-TX Fast Ethernet (IEEE 802.3u) compliant.
• Minimum of CAT 5 cabling is required.
