Product Introduction
The Allen-Bradley 20-COMM-D PowerFlex ControlNet Communication Adapter is a communication interface module designed to enable PowerFlex 70 and PowerFlex 700 drives to integrate into industrial ControlNet networks. It provides a reliable pathway for real-time data exchange between the drive and a PLC-based automation system.
This adapter is used to extend the communication capability of PowerFlex drives without modifying the core drive hardware. By converting internal drive communication into ControlNet protocol, it allows centralized control, monitoring, and diagnostics in distributed industrial systems.
Although it is designed for ControlNet integration, it also supports DeviceNet-style communication characteristics in certain configurations, making it suitable for mixed industrial network environments. It is powered by a low-voltage DC supply and is optimized for compact installation directly on the drive.

FAQ
- What is the main function of the 20-COMM-D adapter?
It enables PowerFlex 70 and PowerFlex 700 drives to communicate with industrial ControlNet or compatible networks for centralized control and monitoring. - Can this adapter be used without a PowerFlex drive?
No, it is designed specifically to operate with compatible PowerFlex 70 and 700 series drives. - What type of communication does it support?
It primarily supports ControlNet communication, with compatibility features for DeviceNet-style integration depending on system configuration. - How is the module powered?
It operates using a 5 VDC low-voltage supply with a current draw of 150 mA. - What is the benefit of using a communication adapter?
It allows legacy drives to be integrated into modern industrial networks without replacing the entire drive system. - Does it affect drive performance?
No, it only handles communication and does not interfere with the internal drive control functions. - Is it suitable for real-time control applications?
Yes, it is designed for deterministic industrial communication used in real-time control systems. - How is it installed?
It is mounted directly onto the PowerFlex drive, enabling plug-in communication expansion. - What happens if communication is lost?
The drive follows its configured fault response behavior, which may include stopping or holding operation depending on settings. - Why is ControlNet used in industrial systems?
ControlNet provides reliable, scheduled, and deterministic communication for high-performance industrial automation networks.
