DeviceNet Plug-in – 2080-DNET20
Overview
The DeviceNet plug-in serves as scanner and client for explicit messaging to
remote devices. The module is designed to scan devices such as:
• CompactBlock™ LDX
• PowerFlex® drives
• E1Plus overloads
• stack lights
User-defined function blocks (UDFB) are required to enable interaction
between these devices.
The 2080-DNET20 DeviceNet scanner supports a maximum of 20 nodes. For
example, if the scanner ID is configured to zero, the scanner would scan from
1…20. It is supported on Micro800 controllers with available plug-in slots. Only
one 2080-DNET20 DeviceNet scanner is supported per controller.
Status Indicators
The DeviceNet plug-in module supports two standard DeviceNet green and red
LED indicators:
• Module status
• Network status
Rockwell Automation recommends that only one 2080-DNET20
DeviceNet scanner be used for each network trunk-line.
If the 2080-DNET20 DeviceNet scanner is control flashed to a new
major firmware version (for example, from 1.xxx to 2.xxx or vice
versa), once the plug-in is successfully upgraded, power cycle the
controller.
If RSLinx browsing is enabled, the CIP client messages can get timed
out because the DeviceNet buffers are fully occupied by RSLinx
messages. It is recommended not to have RSLinx browsing to the
DeviceNet bridge if Client Messaging is required.
