Frequently Asked Questions about 20-COMM-D
Question: What is the purpose of the 20-COMM-D adapter?
Date Update:19/06/2025
Answer:

The 20-COMM-D is a DeviceNet communication adapter used to enable DeviceNet network connectivity for PowerFlex drives and related equipment. It allows these devices to exchange data with other components on a DeviceNet network. It supports various data exchange methods including polled, cyclic, and change-of-state. The adapter acts as an interface between the drive’s internal DPI (Drive Peripheral Interface) and the DeviceNet protocol. This enables seamless integration with industrial control systems using the DeviceNet communication standard.

Question: What devices are compatible with 20-COMM-D?
Date Update:19/06/2025
Answer:

The 20-COMM-D adapter is compatible with Allen-Bradley PowerFlex drives including PowerFlex 70, 700, 700H, 700S, 700L, 750, as well as SMC Flex and SMC-50 smart motor controllers. It is also suitable for use with DPI external communication kits. This wide compatibility allows it to be implemented across various motion and motor control applications. The adapter ensures standardized communication within systems using the DeviceNet network. Always verify compatibility based on firmware and hardware revisions before installation.

Question: What is the power consumption of the 20-COMM-D?
Date Update:19/06/2025
Answer:

The adapter consumes 150 mA at 5V DC when powered by the host drive or DPI kit. It also draws 60 mA at 24V DC when supplied by the DeviceNet network. This low power requirement ensures it can be reliably supported by standard drive power supplies or DeviceNet fieldbus power. It is crucial to consider this current demand when sizing the system’s power budget. Proper electrical design ensures stable operation and prevents undervoltage errors during peak loads.

Question: What protocols are supported by the 20-COMM-D?
Date Update:19/06/2025
Answer:

The 20-COMM-D supports the DeviceNet communication protocol for network interfacing and the DPI (Drive Peripheral Interface) protocol for internal communication with the drive. DeviceNet is a standard fieldbus protocol used in many automation systems. DPI is Rockwell’s proprietary interface for internal drive communication. Together, these protocols ensure that the adapter can act as a translator between the PowerFlex drive and the DeviceNet control network. The adapter also supports multiple data exchange formats including polled, cyclic, and change-of-state messaging.

Question: How is the 20-COMM-D mounted?
Date Update:19/06/2025
Answer:

The 20-COMM-D is designed for panel mounting or internal drive slot mounting. It fits into the communication bay of a PowerFlex drive or into an external DPI communication kit. Mounting should only be done with power turned off to avoid damage due to electrostatic discharge (ESD). Rockwell recommends using anti-static wrist straps and working on grounded surfaces during installation. Secure mounting is essential to prevent vibration-related faults in industrial environments.
