1560-PDP2 Communication Adapter Allen-Bradley Drives SMC-Flex

1560-PDP2 Allen-Bradley SMC-Flex PROFIBUS SCANport Communication Adapter

The Allen-Bradley 1560-PDP2 is a high-speed PROFIBUS DP slave communication interface designed to bridge legacy SCANport motor drives with modern DP networks. Powered by an SPC3 communications chipset, this module processes control words, speed references, and up to 32 real-time parameter values across automated drive line-ups. Incorporating multi-protocol fieldbus translation, it preserves existing variable frequency drive investments while enabling centralized control system upgrades.

Global PLC Spare HUB's Insight & Field Experience

Integrating SCANport legacy architecture into active PROFIBUS DP loops often causes network timing jitter if node configuration is mismanaged. During a recent commissioning project at a water treatment plant, our field automation engineers deployed the 1560-PDP2 module to link a bank of 1336 Plus drives to a Siemens S7-400 controller. The adapter eliminated network timeout faults by using its pre-assigned I/O map for immediate control transfer. Setting the onboard DIP switches for hard-coded hardware addressing prevented software address loss during severe voltage sags on the control line.

Technical Specifications Table

Target Equipment & Field Application Scenarios

• Supported Drive Lines: Direct interface for 1336 Plus, 1397, 1305, SMP3, and SMC-Flex controllers.
• Pumping Station Speed Control: Links multi-drive pumping rigs to centralized supervisory systems.
• Conveyor Line Integration: Provides synchronized speed reference transfers across material handling lines.
• Extruder Motor Diagnostics: Transmits motor temperature, load current, and fault telemetry back to main PLCs.
• Retrofit Engineering: Connects legacy AC/DC drives to modern fieldbus backbones without changing drive power stages.

Hardware Diagnostics & Status Interpretation

• Red / Green PROFIBUS LED: Solid green indicates active DP cyclics; flashing red signals baud rate search or master loss.
• Red / Green SCANport LED: Solid green confirms active serial link to drive host; red indicates port timeout or parity mismatch.
• DIP Switch Configuration Check: Address changes take effect only after power cycling the 85-264 VAC auxiliary supply.
• Bus Termination Verification: Ensure active termination resistors are engaged on the 9-pin D-shell segment ends.

Commercial Guarantees & Global Shipping

• Includes a full 12-Month Warranty backing all operational hardware.
• Fast dispatch window within 24 to 48 hours upon order validation.
• Worldwide priority courier delivery via FedEx, UPS, and DHL.

Engineering Selection Guide & Technical FAQ

Question: What hardware criteria determine if the 1560-PDP2 module fits my drive installation?

Answer: Verify that your host device features a standard 9-pin SCANport connection port and operates within the 85-264 VAC control power spectrum.

Question: Why does the module fail to establish PROFIBUS communications after changing DIP switch positions?

Answer: The internal microprocessor reads hardware address switches during its boot sequence. You must cycle the primary AC input power to register any new DIP address configuration.

Question: Can I route parameter data across multiple bus segments without signal degradation?

Answer: Yes, the module supports network topologies with up to 126 nodes when incorporating 3 line repeaters across the fieldbus run.

Question: How does the 1560-PDP2 affect drive response time in high-speed motion loops?

Answer: The onboard SPC3 chip supports baud rates up to 12 Mbps, providing sub-millisecond update times for mapped control words and speed references.

Question: Is an external 24 VDC power supply required to operate the communication adapter?

Answer: No, the adapter accepts 85-264 VAC power directly and internally converts the 65 mA 24 VDC required for logic circuit execution.
