1336-BDB-SP17C 74101-482-51 Product Description

The Allen-Bradley 1336-BDB-SP17C is a dedicated communication interface board engineered for the 1336 PLUS and 1336 IMPACT series of AC variable frequency drives. Designed to bridge field-level drive data with upper-layer control and monitoring systems, this gateway module enables seamless DeviceNet and Remote I/O (RIO) protocol connectivity — forming a critical node in the industrial data chain that links motor-driven equipment to PLC controllers, SCADA platforms, and smart factory management systems. In environments where real-time drive status, fault diagnostics, speed references, and torque feedback must flow continuously across the automation network, the 1336-BDB-SP17C delivers the protocol translation and network stability required for uninterrupted production visibility.

In a modern smart factory, the 1336-BDB-SP17C functions as the communication backbone between the 1336 PLUS or 1336 IMPACT drive and the broader automation architecture. At the field level, the drive controls motors powering conveyors, pumps, compressors, and fans. Without a network interface, this operational data — speed feedback, output current, fault codes, run/stop status — remains isolated at the drive level. The 1336-BDB-SP17C eliminates this data gap by translating drive-level signals into DeviceNet or RIO messages that travel upstream to the control layer.

A ControlLogix L7x or CompactLogix controller acting as the DeviceNet scanner master polls the 1336-BDB-SP17C at configurable scan rates, retrieving real-time drive parameters and issuing speed references or control commands. In parallel, a 1756-DNB DeviceNet Bridge module or a 1747-SDN SLC 500 DeviceNet Scanner can serve as the network master, coordinating multiple drives and remote I/O nodes on the same DeviceNet segment. For legacy RIO architectures, the 1336-BDB-SP17C connects directly to PLC-5 or SLC 500 RIO networks, enabling backward-compatible integration without replacing existing control infrastructure.

Further up the data chain, a FactoryTalk View SE or FactoryTalk Historian server aggregates drive data from multiple 1336-BDB-SP17C-equipped drives, enabling operators to monitor motor load trends, energy consumption, and fault history from a centralized HMI or SCADA dashboard. Edge gateway devices — such as the Rockwell Automation Stratix 5700 industrial managed switch or a third-party edge computing node — can bridge DeviceNet data to Ethernet/IP or MQTT streams, feeding cloud-based analytics platforms for predictive maintenance and OEE tracking. Remote I/O racks equipped with 1771-ASB adapter modules extend the data reach to distributed field panels, ensuring that even geographically dispersed drive installations remain visible within the SCADA network.

For multi-drive applications, the 1336-BDB-SP17C supports coordinated control scenarios where a single PLC manages speed ratios across several 1336 PLUS drives on a common DeviceNet segment — a configuration common in web tension control, multi-pump pressure management, and synchronized conveyor systems. Alarm and fault data generated by the drive is transmitted in real time to the controller and surfaced on operator panels such as the PanelView Plus 7, enabling rapid fault acknowledgment and minimizing unplanned downtime. The complete data loop — from signal acquisition at the motor shaft encoder, through protocol conversion at the 1336-BDB-SP17C, across the DeviceNet or RIO network, into the PLC scan table, and up to the SCADA historian — forms the foundation of a transparent, data-driven production environment.

Many industrial facilities operating 1336 Series drives face a common challenge: the drives contain rich operational data — output frequency, DC bus voltage, fault history, thermal status — but without a communication interface, this data cannot reach the control system or SCADA layer. The result is reactive maintenance, manual parameter checks at the drive keypad, and blind spots in production reporting.

The 1336-BDB-SP17C directly resolves these data isolation problems. By enabling DeviceNet or RIO connectivity, it transforms a standalone drive into a networked node that participates fully in the plant's automation data flow. Protocol unification is achieved without replacing the drive or the PLC — the option board slots into the existing 1336 drive chassis, and the network master immediately recognizes it as a standard DeviceNet device or RIO adapter. This approach eliminates the protocol mismatch that often exists between legacy drives and modern Ethernet-centric control systems, bridging the gap until a full drive upgrade is feasible.

Remote diagnostics become possible once the 1336-BDB-SP17C is online. Maintenance engineers can read fault codes, monitor thermal derating conditions, and verify speed references from the control room or via remote access to the SCADA system — eliminating the need for physical inspection of panel-mounted drives in hazardous or hard-to-reach locations. Production line transparency improves as drive runtime hours, start/stop cycles, and energy data are logged automatically by FactoryTalk Historian, enabling data-driven maintenance scheduling and reducing unplanned stoppages. System expansion is straightforward: additional 1336 drives equipped with 1336-BDB-SP17C boards can be added to the DeviceNet segment up to the network node limit, scaling the connected drive network without architectural redesign.

Q1: What communication protocols does the 1336-BDB-SP17C support, and which PLC platforms are compatible? The 1336-BDB-SP17C supports DeviceNet and Remote I/O (RIO) protocols. It is compatible with Allen-Bradley ControlLogix, CompactLogix, SLC 500, and PLC-5 platforms. DeviceNet master modules such as the 1756-DNB or 1747-SDN serve as the network scanner, while RIO configurations connect directly to PLC-5 or SLC 500 RIO ports. All units are pre-tested for network communication before shipment.

Q2: How does the 1336-BDB-SP17C contribute to SCADA integration and remote monitoring? Once installed, the module exposes drive parameters — speed reference, output frequency, current, fault status — as DeviceNet or RIO data objects readable by the PLC. This data is then available to SCADA systems such as FactoryTalk View SE or Ignition via the PLC's data table, enabling real-time dashboards, alarm management, and historical trending without additional hardware. Remote diagnostics can be performed through the SCADA interface, reducing on-site maintenance visits.

Q3: What is the network stability and communication latency of the 1336-BDB-SP17C on a DeviceNet segment? DeviceNet operates at selectable baud rates of 125 kbps, 250 kbps, or 500 kbps. At 500 kbps with a properly terminated and shielded cable run, the 1336-BDB-SP17C delivers deterministic scan cycle times suitable for closed-loop speed control applications. Network stability depends on correct termination resistors at both ends of the trunk cable and adherence to DeviceNet drop length limits. All units supplied by NANKMOS are tested for communication integrity prior to dispatch.

Q4: Does the 1336-BDB-SP17C come with a warranty, and what is the lead time? Yes. All 1336-BDB-SP17C units supplied by NANKMOS carry a 12-Month Warranty covering manufacturing defects and communication functionality. Units are available from stock with short lead times.
