Configuration Recommendations
•
Recommended Ethernet addressing scheme (see
):
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.
