Description

PM5650-2ETH 1SAP141000R0278: Product Overview
The PM5650-2ETH 1SAP141000R0278 is a CPU module within ABB’s AC500 series of programmable logic controllers (PLCs), designed for deployment as the central processing unit in small- to medium-scale industrial automation systems. Its role is to serve as the control brain, executing user-developed logic (e.g., ladder diagram, function block diagram) to manage discrete and analog I/O, coordinate sequential processes, and facilitate communication with supervisory systems. For industries such as manufacturing, water treatment, and energy distribution, it provides deterministic control for applications like assembly line robotics, pump station monitoring, and batch mixing—where reliability and network integration are critical.
Functionally, the module processes inputs from AC500 series I/O modules (e.g., DI810 digital input, AI810 analog input) and outputs control commands to actuators (valves, motors). It features two Ethernet ports for redundant or segmented network communication, supporting protocols like Modbus TCP, Ethernet IP, and PROFINET. As part of the AC500 family, the PM5650-2ETH 1SAP141000R0278 leverages ABB’s modular platform advantages: compatibility with CODESYS V3 programming environment, hot-swappable components, and seamless integration with ABB 800xA DCS for expanded system scope. This design simplifies engineering, reduces lifecycle costs, and enables scalable growth from standalone PLCs to distributed control architectures.

Core Features & Customer Value​
Dual Ethernet Ports Enhance Network Reliability: The PM5650-2ETH 1SAP141000R0278 includes two independent Ethernet ports, enabling redundant communication (primary/backup) or segmented network topologies (e.g., separating I/O traffic from SCADA). For engineers managing critical systems like water treatment pump stations, this prevents single-point network failures—if one port/cable fails, the other maintains data flow to HMIs and historians. Redundant setups reduce unplanned downtime by 90% compared to single-port configurations.
High-Performance Processing for Complex Logic: The 32-bit PowerPC 405 processor (266 MHz) and 512MB RAM support execution of large logic programs, including PID loops, motion control sequences, and data logging. In a manufacturing assembly line, this allows real-time coordination of 10+ robotic arms via Ethernet IP, ensuring synchronized part placement with <10ms latency.
CODESYS V3 Programming Simplifies Development: As a CODESYS V3-compatible controller, the module uses a standardized IEC 61131-3 programming environment, reducing training time for engineers familiar with other CODESYS-based PLCs. Reusable function blocks (e.g., motor starter, alarm handler) cut programming time by 30% in projects like batch chemical mixing, where similar logic repeats across multiple reactors.
AC500 Platform Scalability for Future Growth: The module integrates with AC500 I/O expansion racks (local/remote) and ABB 800xA DCS, allowing systems to scale from 50 to 500+ I/O points without replacing the CPU. For a growing food processing plant, this means adding a remote I/O rack for a new packaging line—no full system redesign required.
Rugged Design for Industrial Environments: With an operating temperature range of -25°C to +60°C and compact size (120x100x75mm), the module fits into control cabinets near machinery (e.g., machine tools, conveyors). Its 24V DC power supply aligns with standard industrial power distribution, simplifying integration.

Typical Applications​
The PM5650-2ETH 1SAP141000R0278 is deployed in PLC-controlled systems requiring Ethernet connectivity. In an automotive assembly plant, it controls robotic welding stations: 2 Ethernet ports connect to robot controllers (Ethernet IP) and the plant’s Siemens WinCC SCADA (Modbus TCP), enabling real-time weld quality monitoring.
At a municipal water treatment plant, the module manages 8 pump stations via remote AC500 I/O racks. One Ethernet port handles I/O data (pump status, flow rates), while the second connects to the plant’s Historian for remote trend analysis—alerting operators to clogged filters before pressure drops.
In a pharmaceutical batch reactor, the PM5650-2ETH 1SAP141000R0278 executes temperature/agitation control logic via CODESYS V3. Ethernet IP links to a LabVIEW HMI for recipe management, while the second port backs up data to a local server—ensuring compliance with FDA 21 CFR Part 11 record-keeping.
