DeviceNet Connector Pins and Signals (P2)
Planning Your DeviceNet Network
A DeviceNet network is a planned arrangement of electrical power
and device distribution that is adjusted for optimal communications.
Before you add devices, record the following:
• Network data rate
• Network cable system map (topology) to which you are connecting
• Distances between cable system components
• Device current draw and voltage drop for each device on the
network
• Limitation of the trunk and drop cables
Refer to the table below for recommended trunk and drop lengths.
Refer to the DeviceNet Cable System Planning and Installation
Manual (publication DN-6.7.2) for specific guidance in calculating
and attaching the Ultra5000 to a network.
