EtherNet/IP and Industrial Drive Communication Integration
The 22-COMM-M uses Allen-Bradley DPI communication architecture to exchange drive status, control commands, and diagnostic information through Modbus/TCP networks. The adapter supports Ethernet communication rates from 10 Mbps to 100 Mbps with half-duplex and full-duplex operation modes.
The module is designed for PowerFlex drive installations requiring external network access without direct modification of the drive control hardware. Its DPI connector provides the internal communication path to compatible drive platforms, while the RJ45 interface provides Ethernet network connectivity.
Frequently Asked Questions
Q: What is the power source for the 22-COMM-M communication adapter?
A: The adapter receives operating power from the connected host drive or DPI External Communication Kit. The specified drive electrical consumption is 350 mA at 5 VDC.
Q: Does the 22-COMM-M require an external network power supply?
A: No. The network electrical consumption is specified as none. The module receives power through the host DPI interface connection.
Q: What communication connections are supported by the adapter?
A: The adapter supports up to 30 TCP connections, including up to 16 simultaneous CIP messaging connections and one Modbus/TCP I/O connection.
Field Installation Guidelines
Install the 22-COMM-M adapter inside the compatible PowerFlex drive or approved DPI communication enclosure according to the drive hardware installation procedure.
Connect the DPI interface firmly to the designated drive communication connector before applying power. Use shielded Ethernet cabling for the RJ45 network connection where required by the industrial environment. Maintain separation between communication wiring and high-voltage power conductors to reduce electromagnetic interference.
Verify that the adapter LEDs indicate normal DPI, adapter, and network communication status after installation. Confirm firmware compatibility between the communication adapter and the connected PowerFlex drive before commissioning network communication functions.
For panel-mounted installations, maintain the enclosure protection rating requirements and ensure proper grounding of metallic mounting structures and cable shields according to site electrical standards.
