B-2 DeviceNet to SCANport Communication Module with Digital Inputs Parameters
2. Set the DN Node Address (2) parameter to the desired address.
3. Reset the adapter by setting the Reset Adapter (22) parameter to
Enable.
Setting the Data Rate The DeviceNet to SCANport Communication Module with Digital
Inputs supports the following data rates:
• 125 Kbps
• 250 Kbps
• 500 Kbps
• Autobaud
The adapter defaults to using autobaud data rate detection.
Important: At least one continually transmitting device on the
network (usually the scanner) must be set to a fixed data rate (not
autobaud). This device sets the data rate for the network that the other
nodes using autobaud detect.
If you want to change your adapter’s data rate, you need to:
1. Access the adapter’s parameters using the DeviceNet network
(refer to Chapter 3, Configuring the DeviceNet to SCANport
Communication Module with Digital Inputs).
2. Set the DN Data Rate (3) parameter to the desired value. Refer to
the following table for information on acceptable values.
Before connecting modules to the network, you must determine if
your network is within the limits of the cable system. Class 1 cables
are rated 600 volts, 8 amps. Class 2 cables are rated 300 volts, 4 amps.
The cables in the chart below can be used for Trunk or Drop
applications. When used for Trunk, length limits must be observed.
Class 1 round drop cable is recommended for connections between
devices and Class 1 Trunk. Maximum drop length is 6m (20 ft.).
Cumulative Drop Budget is based on Data Rate.
