To avoid errors
In order to minimize the number of errors encountered in cabling DeviceNet, take the following actions:
1) Perform the calculations described in section D.9. 1, regarding current requirements, length of cable and
type of cable
2) look at section D.lO. Conduct voltage measurements when the network is built. Especially, look at:
1)Maximum voltage drop on Vn and V+
2) Voltage range at each node
3) allow a margin to correct the network configuration
4) for multiple supply: turn on all supply simultaneously
