Allen-Bradley 1203-CN1 Ethernet Communication Module – 1203 Series SCANport Adapter
Imagine a high-speed production line grinding to a halt — not because of a mechanical failure, but because the drive can no longer communicate with the control network. Without a reliable communication adapter, your Variable Frequency Drive becomes an isolated island, invisible to your PLC, SCADA system, and plant-wide Ethernet infrastructure. Downtime accumulates. Engineers scramble. The cost per minute climbs. The Allen-Bradley 1203-CN1 exists precisely to prevent this scenario, bridging your SCANport-equipped drives seamlessly into your ControlNet or Ethernet/IP network fabric.
Within the Allen-Bradley 1203 Series communication adapter family, the 1203-CN1 occupies a critical position as the ControlNet-to-SCANport gateway. It is engineered for Rockwell Automation’s PowerFlex and 1336 PLUS II drive families — platforms that power tens of thousands of industrial installations worldwide across automotive, water treatment, oil & gas, and material handling sectors. For engineers specifying network-integrated drive solutions, the 1203-CN1 is a proven, field-validated component with a global installed base.

Key Features & Benefits
- Seamless SCANport Integration: Plugs directly into the SCANport peripheral port on compatible Allen-Bradley drives — no additional wiring harness required.
- ControlNet Connectivity: Enables deterministic, high-speed ControlNet communication for time-critical drive control applications.
- Parameter Access via Network: Allows full read/write access to drive parameters from a remote PLC or HMI over the network, eliminating the need for local drive access during commissioning or troubleshooting.
- Plug-and-Play Architecture: Designed for rapid field installation and replacement, minimizing maintenance downtime.
- Rockwell Ecosystem Compatibility: Fully compatible with RSLogix 5000 / Studio 5000 programming environments and RSNetWorx for ControlNet configuration.
- Compact Form Factor: Lightweight external module that does not require drive enclosure modification.
Industry & Equipment Applications
- Automotive Manufacturing: Conveyor drive control integrated into plant-wide ControlNet networks for synchronized production line management.
- Water & Wastewater Treatment: Pump and blower VFD monitoring and control via SCADA systems using ControlNet backbone.
- Oil & Gas: Remote parameter monitoring of compressor and pump drives in hazardous-area installations where local access is restricted.
- Material Handling & Logistics: Coordinated multi-drive control for sorting systems, palletizers, and automated storage and retrieval systems (AS/RS).
- Food & Beverage Processing: Hygienic-area drive integration where remote network control reduces the need for personnel entry into processing zones.
- Mining & Minerals: Belt conveyor and crusher drive network integration for centralized monitoring in remote or harsh environments.
System Integration & Compatible Parts
The 1203-CN1 is designed to work within a broader Rockwell Automation control architecture. Commonly paired components include:
- Allen-Bradley PowerFlex 70 / PowerFlex 700 Variable Frequency Drives
- Allen-Bradley 1336 PLUS II / 1336 IMPACT / 1336 FORCE AC Drives
- 1784-PCIC / 1784-PKTX ControlNet Interface Cards (for PC-based configuration)
- 1786-RPA / 1786-RPCD ControlNet Repeaters (for extended network segments)
- ControlLogix / CompactLogix PLCs with 1756-CNB or 1769-SDN scanner modules
- RSNetWorx for ControlNet (network configuration software)
When sourcing the 1203-CN1, also consider verifying firmware compatibility between the adapter and your specific drive firmware revision to ensure full feature support.
Our Quality Assurance Process
At Konmask.com, every Allen-Bradley 1203-CN1 unit passes through a structured sourcing and verification process before dispatch:
- Source Verification: Units are sourced from authorized distributors, certified surplus dealers, or directly from decommissioned OEM installations with documented service history.
- Visual & Physical Inspection: Each module is inspected for connector integrity, housing condition, label legibility, and absence of physical damage or corrosion.
- Functional Testing (where applicable): Surplus and refurbished units undergo bench-level power-on and communication handshake testing prior to shipment.
- Authentic Packaging: New units are supplied in original Allen-Bradley packaging with full documentation where available.
- Traceability: Lot and date codes are recorded for every shipment to support your incoming inspection and quality records.

Frequently Asked Questions
Q: Is the 1203-CN1 compatible with PowerFlex 4 or PowerFlex 40 drives?
A: No. The 1203-CN1 uses the SCANport interface, which is present on PowerFlex 70, PowerFlex 700, and the 1336 family. PowerFlex 4/40 drives use a different peripheral interface (DSI) and require a different adapter series (e.g., 22-COMM-C for ControlNet).
Q: Can I use the 1203-CN1 on an EtherNet/IP network?
A: No. The 1203-CN1 is a ControlNet adapter. For EtherNet/IP connectivity on SCANport drives, the correct module is the 1203-EN1 (or 20-COMM-E for newer PowerFlex drives).
Q: What is the difference between the 1203-CN1 and the 1203-GU6?
A: The 1203-GU6 is a universal gateway module supporting multiple network protocols, while the 1203-CN1 is dedicated to ControlNet. The CN1 is preferred when a single, deterministic ControlNet connection is required.
Q: Do you provide a warranty on surplus units?
A: Yes. Konmask.com offers a limited warranty on tested surplus units. Warranty terms are confirmed at the time of quotation based on unit condition and sourcing history.
Q: How long does international shipping take?
A: Typical international delivery is 5–15 business days depending on destination country, customs clearance, and chosen freight method. Express options are available on request.
