825-PDN DeviceNet Communication Card Chapter 9
Features The 825-P 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 825-P Modular Protection System 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 825-P
Modular Protection System as installed.
• UCMM (Unconnected Message Manager) messages are supported with
the ability to allocate up to 3 explicit message connections concurrently.
• DeviceNet Group 2 slave functionality including:
–
Explicit connection
– Polled connection
– 1 COS (Change of State)/Cyclic connection
• Full DeviceNet Parameter Object support allows EDS files to be extracted
from all units.
• Settings are provided for user-defined behavior of the 825-P Modular
Protection System auxiliary relays for Comm Fault and Comm Idle
conditions.
• Group 4 faulted node recovery is supported. You can configure a device
even when it is faulted on the network if the configuration tool supports
faulted node recovery.
• DeviceLogix component technology provides the capability to perform
logic operations at the device level. A total of 80 function blocks are
supported.
