Product Overview
The ALLEN-BRADLEY 1203-CN1 is a dedicated ControlNet communications module designed to serve as a high-performance network interface between the ControlNet industrial control network and a single SCANport-enabled device-1-4. This specialized ALLEN-BRADLEY 1203-CN1 module allows any SCANport-equipped member of the Allen-Bradley standard drives family—including the popular 1336 PLUS and other adjustable frequency drives—to be seamlessly connected to a ControlNet network, enabling advanced control, monitoring, and data exchange capabilities-2-5. As a cornerstone of legacy Rockwell Automation distributed control architectures, the ALLEN-BRADLEY 1203-CN1 provides deterministic I/O control and unscheduled messaging, leveraging ControlNet’s open communication protocol features such as redundant media support and real-time data exchange-9.
The ALLEN-BRADLEY 1203-CN1 module bridges the gap between SCANport peripherals and modern industrial networks, offering substantial operational benefits including high-speed I/O control and the ability to perform explicit messaging to access drive parameters and status data. Supporting both CIP (ControlNet Information Protocol) and PCCC (Programmable Controller Communication Commands) messaging, the ALLEN-BRADLEY 1203-CN1 is compatible with a wide range of controllers, from legacy PLC-5 systems to modern ControlLogix platforms-3-5. Its rugged design, DIN rail mounting capability, and comprehensive status indicators ensure reliable performance in demanding industrial environments-2-5. Today, the ALLEN-BRADLEY 1203-CN1 remains a critical component for maintaining operational continuity in automation systems where the SCANport to ControlNet interface is essential for drive control and process monitoring-2-9.
