20-COMM-E Functional Description

The 20-COMM-E ROCKWELL Communication Module is an essential Ethernet/IP communication adapter designed specifically for PowerFlex 70 and 700 series drives, enabling seamless integration into industrial Ethernet networks for advanced monitoring and control capabilities. This versatile module supports multiple network speeds including 10/100 Mbps in both full and half duplex modes, while handling up to 30 TCP connections or 16 simultaneous CIP connections with a fast 5ms RPI rate.It efficiently processes up to 400 I/O packets per second, making it ideal for real-time industrial automation applications requiring high-speed data exchange.

Designed for robust industrial environments, the 20-COMM-E PowerFlex VSD Single Port EtherNet IP Communication Module meets stringent UL508C, CAN/CSA, and EN standards, operating reliably in temperatures from -10 to 50°C with 5-95% non-condensing humidity. Its compact dimensions (78.5×86×19mm) and lightweight design (85g) allow for easy integration without occupying significant panel space. The Allen-Bradley 20-COMM-E draws minimal power (350mA) directly from the host drive, simplifying installation while maintaining energy efficiency in continuous operation. However, it requires protection from corrosive environments and may cause radio interference in domestic settings.

The EtherNet/IP to DPI Adapter Allen-Bradley 20-COMM-E offers broad controller compatibility, supporting communication with ControlLogix, CompactLogix, PLC5, SLC500, and MicroLogix platforms, though performance varies across different controller types. This adapter enables powerful features like exclusive-owner I/O connections for precise drive control, while its industrial-grade construction ensures durability in demanding manufacturing conditions. Installation requires drive power-off for safety, following recommended procedures to prevent system disruptions. The 20-COMM-E PowerFlex Ethernet-IP Adapter AB serves as a critical component for modernizing legacy systems with Ethernet/IP capabilities.

As part of Rockwell Automation's PowerFlex ecosystem, the Allen-Bradley 20-COMM-E EtherNet/IP to DPI Adapter bridges the gap between advanced drive technology and contemporary network architectures. Its ability to maintain stable connections in challenging environments makes it particularly valuable for industries implementing Industry 4.0 solutions. The adapter's combination of high-speed communication, compact design, and extensive compatibility positions it as an optimal solution for upgrading existing PowerFlex drives with network connectivity while maintaining system reliability and performance standards.
