Get Started 1-3
Decide whether to use DeviceLogix  /EE-capable I/O to run
internal, programmable logic within the actual devices for fast
execution rates.
Document the data table requirements for each node. This
information will help you develop the control platform user
program.
3. What type of network media is best for my application?
For help in determining which media best fits your application,
refer to the following publications:
Determine whether you need a Class 1 or Class 2 cabling system.
Choose sealed or unsealed media for your application’s
environment.
Choose the maximum trunk length allowable within specifications
for the cable type and communication baud rate.
Ensure that your cumulative cable drop length is within
specifications for the network baud rate.
Ensure that all individual drop line lengths are </= 20 ft. (6m).
Ensure that you have one 121 Ω terminating resistor at each end of
the trunk line.
4. Which power supply will be adequate for my application?
Refer to this publication for further details on selecting a power
supply.
5. How do I configure my network?
You can use RSNetWorx for DeviceNet software to generate an
offline configuration file which contains all the I/O mapping for
your system. This file will help you develop a control platform user
