Allen-Bradley 20-COMM-D is a DeviceNet communication adapter designed for integration with PowerFlex 70, 700, and 753 series AC drives. This adapter enables networked control and monitoring, supporting up to 63 nodes on a single network. It operates on 24V DC with a 0.15A current draw and is a key component for building distributed control systems within the Rockwell Automation architecture.

Product Details

Communications Modules

EtherNet - The 22-COMM-E EtherNet/IP adapter provides an internal EtherNet/IP connection for PowerFlex 40 drives. The adapter allows the drive to be controlled, configured, and data to be collected via an EtherNet/IP network. Web services are also provided and pages can be viewed with standard web browsers. The adapter also supports "Multi-Drive", a unique feature to Allen-Bradley. Multi-Drive allows up to five PowerFlex component class drives to connect to a single node on EtherNet/IP. Benefits include reduced hardware costs and a means to connect PowerFlex 4 drives to EtherNet/IP.
User configurable process display window
TCP/IP configuration (monitor only)
Email notification on fault, fault clear, and/or when the adapter takes its comm or idle fault actions
Monitoring device information, diagnostics and event queue
Direct launching of DriveExplorer or DriveExecutive on user's PC to connect on-line over EtherNet
DeviceNet - The PowerFlex 40 (not the PowerFlex 4) can be integrated with Allen-Bradley PLC Architectures using this optional DeviceNet communications module.
Network - The PowerFlex 70 can be integrated with PLC Architectures using these communications modules which fit neatly inside the PowerFlex 70.

Note

A comms option cover is also needed for EtherNet & DeviceNet modules – choose the cover to match the PowerFlex 40 frame size (B or C).

Allen Bradley Adapter For Use With PowerFlex Series, 19mm Length, 78.5mm Depth - 20-COMM-D

This adapter from Rockwell Automation's Allen Bradley range is an embedded communication tool designed for use with drives in the PowerFlex series. It enables easy control of your drives and also serves as a channel for data collection. Its compact dimensions of 19 (length) and 78.5mm (depth) make it suitable for small spaces. This device's switches let you set a node address and network data rate before powering the drive to eliminate the need for external configuration software. The unit also comes with captive screws that secure it to the drive, so it won't fall off when used with vibrating systems.
Compatible with DeviceNet and DriveExplorer software for quick and easy interfacing with computersLight-emitting diode (LED) status indicators show operating conditions for easy troubleshootingSupplied with grounding wrist strap for protection from electrostatic discharge (ESD)
