Deterministic Networks and DPI Backplane Communication
The 20-COMM-D adapter provides DPI interface communication between Allen-Bradley PowerFlex drives and DeviceNet networks. The module receives 5 VDC power from the host drive or DPI external communication kit with a defined electrical consumption of 150 mA. DeviceNet network power is supplied through the communication network at 24 VDC with a 60 mA consumption profile.
The adapter supports selectable DeviceNet baud rates of 125K, 250K, and 500K, with node address selection and data rate configuration switches integrated into the hardware. DPI communication maintains direct drive parameter access for connected PowerFlex platforms.
Frequently Asked Questions (FAQ)
Q: Which drive platforms support the 20-COMM-D communication adapter?
A: The adapter supports PowerFlex 70, PowerFlex 700, PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, PowerFlex 750 drives, DPI external communication kits, SMC Flex, and SMC-50 smart motor controllers.
Q: How is the 20-COMM-D powered during operation?
A: The adapter receives 5 VDC power from the host drive or DPI external communication kit. Additional network power is supplied through the DeviceNet connection at 24 VDC.
Q: What physical interfaces are available on the module?
A: The module contains one 20-pin DPI connector and one 5-pin DeviceNet connector for drive and network communication.
Field Installation Guidelines
Install the 20-COMM-D adapter using the specified panel mounting arrangement inside an enclosure meeting the required environmental protection level. Verify that the DPI connector is fully seated before applying power.
DeviceNet wiring should maintain separation from high-voltage power conductors and motor cables to reduce electrical interference. Cable shielding should follow the DeviceNet network grounding requirements, with shield termination connected according to the control cabinet grounding design.
Confirm DeviceNet node address and baud rate switch settings before network commissioning. Check LED status indicators after power-up to verify drive communication, adapter operation, and network connection status.
