Product Overview

ABB RDNA-01 Replacement & Upgrade Solution for RDNA Series: Seamless Transition from Legacy Drive Fieldbus Systems

The ABB RDNA-01 is a DeviceNet fieldbus adapter module designed for integration with ABB’s AC drive platforms, including the widely deployed ACS800, ACS550, and ACS880 series. As industrial facilities transition away from aging drive communication architectures, the RDNA-01 serves as both a direct replacement for failed or end-of-life units and a validated upgrade path for sites migrating from earlier fieldbus implementations. TOPNLMS maintains verified stock of the RDNA-01 to support urgent replacement requirements, planned retrofit projects, and multi-site standardization programs.

For plants operating legacy ABB drives with older RDNA-series adapters or proprietary communication cards, the RDNA-01 provides a plug-compatible upgrade that preserves existing DeviceNet wiring infrastructure. The module slots directly into the drive’s option slot, eliminating the need for panel rewiring or PLC program restructuring in most retrofit scenarios. Engineers migrating from discontinued ABB fieldbus cards such as the RDCO-01 (DDCS fiber optic adapter) or transitioning from hardwired I/O to DeviceNet network topology will find the RDNA-01’s standard MAC ID configuration and baud rate auto-detection significantly reduce commissioning time on the factory floor.

In distributed drive systems where the ACS800 multidrives or ACS880 multidrives are controlled via a DeviceNet master — typically a Rockwell Automation ControlLogix or CompactLogix PLC, or an ABB AC500 controller — the RDNA-01 enables seamless cyclic data exchange using standard DeviceNet I/O messaging. The module supports both polled and change-of-state (COS) I/O connections, making it compatible with existing scanner configurations without requiring EDS file updates in most cases. Sites running Allen-Bradley 1756-DNB or 1769-SDN DeviceNet scanner modules can integrate the RDNA-01 into their existing network without topology changes.

Physical installation follows ABB’s standard option module mounting procedure. The RDNA-01 occupies a single option slot on compatible ACS800 and ACS880 drive frames, with the DeviceNet connector (5-pin open-style or sealed M12, depending on variant) accessible from the front of the drive cabinet. For installations in compact control cabinets where space is constrained, the module’s low-profile form factor and front-access wiring simplify integration alongside other option modules such as the RAIO-01 analog I/O extension or the RTAC-01 pulse encoder interface. Power for the RDNA-01 is drawn internally from the drive’s option slot supply, eliminating the need for an external 24 VDC auxiliary power feed.

For sites upgrading from standalone drives to a networked architecture, the RDNA-01 enables the drive to participate in a DeviceNet segment alongside other field devices — including ABB SREA-01 Ethernet adapter-equipped drives, remote I/O blocks, and distributed safety modules — without requiring a separate gateway or protocol converter. This is particularly valuable in brownfield retrofit projects where the existing DeviceNet trunk cable and drop lines are retained, and only the drive-side adapter requires replacement.

Migration projects involving the replacement of older ABB ACS600 or ACS400 drives with current ACS880 units frequently require a corresponding adapter module update. In these cases, the RDNA-01 replaces legacy communication options that are no longer manufactured, restoring DeviceNet connectivity on the new drive platform while maintaining compatibility with the existing PLC program’s drive parameter mapping. TOPNLMS can supply the RDNA-01 alongside compatible ACS880-01 drive units and ZMU-02 memory units to support complete drive replacement packages.

All RDNA-01 units supplied by TOPNLMS are sourced from verified supply channels, inspected prior to dispatch, and shipped with full documentation. Each unit is covered by a 12-month warranty from the date of shipment. Orders placed before the daily cutoff are processed same day, with express international shipping available to minimize plant downtime during emergency replacement scenarios.

Seamless Upgrade Solutions

A complete drive communication retrofit typically involves more than a single adapter module. When replacing the RDNA-01 or upgrading a legacy drive system to DeviceNet, the following components are commonly required in the same project scope:

The RAIO-01 analog I/O extension module is frequently installed alongside the RDNA-01 in ACS800 drives where additional analog reference or feedback signals must be routed independently of the fieldbus. For drives requiring encoder feedback during the migration from open-loop to closed-loop vector control, the RTAC-01 pulse encoder interface module occupies a second option slot without conflicting with the RDNA-01’s DeviceNet connection. In multi-drive panels where the ACS880 replaces older ACS600 units, the ZMU-02 memory unit allows parameter sets to be transferred between drives, reducing re-commissioning time significantly.

On the network infrastructure side, projects migrating from hardwired I/O to DeviceNet often require DeviceNet trunk cable (thick or thin media), T-tap connectors, and termination resistors to complete the segment. Where the existing PLC rack does not include a DeviceNet scanner, an Allen-Bradley 1756-DNB scanner module or equivalent is added to the ControlLogix chassis. For ABB AC500-based control systems, the CM572-DN DeviceNet master module provides the scanner function within the AC500 rack.

In installations where signal isolation between the DeviceNet segment and legacy analog I/O wiring is required, a DIN-rail mounted signal isolator (such as the Phoenix Contact MINI MCR series or equivalent) is typically added to the control cabinet. HMI integration is commonly handled via an ABB CP600 operator panel or a Siemens SIMATIC HMI TP700 connected to the PLC, providing drive status visualization without requiring direct communication with the RDNA-01.

Retrofit Guidance FAQ

Q: Can the RDNA-01 reuse existing DeviceNet wiring from the replaced adapter?
A: Yes. The RDNA-01 uses standard DeviceNet signaling (CAN physical layer). Existing trunk cable, drop lines, and T-tap connectors are fully reusable provided the segment termination and cable lengths comply with DeviceNet media specifications. No rewiring of the DeviceNet segment is required in most retrofit scenarios.

Q: Does replacing the adapter module require changes to the PLC program?
A: In most cases, no. If the replacement RDNA-01 is configured with the same MAC ID and the drive’s parameter mapping (PPO type) matches the existing scanner configuration, the PLC program requires no modification. If migrating from a different protocol (e.g., Profibus to DeviceNet), the scanner module and associated PLC logic will require updating.

Q: What drive firmware version is required for RDNA-01 compatibility?
A: Compatibility depends on the drive model. For ACS800, firmware version 7.x or later is recommended. For ACS880, standard firmware supports the RDNA-01 from initial release. Always verify the drive’s option module compatibility list in the relevant hardware manual before installation.

Q: Is the RDNA-01 compatible with both ACS800 and ACS880 option slots?
A: The RDNA-01 is designed for the ACS800 option slot form factor. ACS880 drives use the Zxx option module series (e.g., ZDNA-01 for DeviceNet). Confirm the target drive model before ordering to ensure the correct adapter variant is supplied.

Q: How much physical space does the RDNA-01 require in the control cabinet?
A: The RDNA-01 mounts internally within the drive’s option slot and does not require additional DIN-rail space in the control cabinet. The DeviceNet connector is accessible from the drive’s front or side, depending on the drive frame size.

Q: What is the commissioning procedure after installation?
A: Set the MAC ID using the rotary switch before powering the drive. Configure the baud rate (or enable auto-detect). Power on the drive and verify the RDNA-01 LED status indicators show network active and no fault. Add the device to the DeviceNet scanner’s scan list using the EDS file and configure the I/O connection type and data size to match the existing configuration.
