Figure E.2 DeviceNet Card Component Overview
Features
The DeviceNet Communication Card features the following:
➤ The card receives the required power from the DeviceNet
network.
➤ Rotary switches let you set the node address and network data
rate prior to mounting in the SEL-749M and applying power.
Alternatively, the switches can be set to positions that allow for
configuration of these settings over the DeviceNet network,
utilizing a network configuration tool such as RSNetWorx for
DeviceNet.
➤ Status indicators report the status of the device bus and network
communications. They are visible from the back panel of the
SEL-749M as installed.
You can do the following with the DeviceNet interface:
➤ Retrieve metering data such as the following:
➢ Currents
➢ Vo lt ag e s
➢ Power
➤ Retrieve motor statistics data
Node Address Switch—Rotary switch for setting the
least significant digit (LSD) of node address.
Data Rate Switch—Rotary switch for selecting the
DeviceNet data rate at which the card
communicates.
Node Address Switch—Rotary switch for setting the
most significant digit (MSD) of node address.
Network Status LED—Status indicator for
DeviceNet communications.
Bus Status LED—Status indicator for backplane
communications.
DeviceNet Connector—Accepts a 5-pin linear
DeviceNet plug.
