Description
ABB PM556-TP-ETH: Product Overview
The ABB PM556-TP-ETH is a compact, all-in-one programmable logic controller (PLC) with an integrated touchscreen human-machine interface (HMI), designed for decentralized industrial automation. Part of ABB’s PM500 Series, it merges PLC logic execution, HMI visualization, and Ethernet communication into a single unit, simplifying machine control and reducing cabinet space.
Targeted at small-to-medium automation tasks, the PM556-TP-ETH serves as a standalone controller for machines (e.g., packaging equipment, material handling systems) or as a distributed node in larger networks. Its integrated 4.3-inch color touchscreen allows operators to monitor process variables, adjust setpoints, and acknowledge alarms locally, while the Ethernet port enables remote programming, data logging, and integration with SCADA/MES systems. The unit supports ABB’s CODESYS programming environment, ensuring compatibility with global automation standards.

PM556-TP-ETH
Core Features & Customer Value
-
All-in-One Design: Integrates PLC, HMI, and Ethernet communication into a single compact unit, reducing wiring complexity and cabinet space by up to 40% compared to separate PLC+HMI setups. Ideal for space-constrained machines like labeling equipment or small conveyors.
-
Intuitive Touchscreen HMI: The 4.3-inch resistive touchscreen enables drag-and-drop screen creation (via CODESYS HMI editor), allowing operators to visualize real-time data (temperatures, pressures, cycle counts) and adjust parameters without external devices.
-
Ethernet Connectivity: The 10/100 Mbps port supports seamless integration with factory networks, enabling remote monitoring via SCADA systems (e.g., ABB Ability™ System 800xA) and cloud-based data logging for predictive maintenance.
-
Scalable I/O Expansion: Onboard I/O (8DI/6DO) can be expanded to 256 points using ABB PM5xx series modules (digital, analog, specialty I/O), adapting to growing automation needs (e.g., adding sensors to a packaging line).
-
Robust Performance: The 400 MHz processor and 128 MB RAM handle complex logic (e.g., motion control sequences, PID loops) with scan times <10 ms, ensuring responsive machine operation.
Typical Applications
The ABB PM556-TP-ETH is widely used in decentralized automation:
-
Machine Automation: Controls packaging machines (timing, sealing, labeling), small CNC routers, and material handling systems (conveyor speed, sorting gates).
-
Process Control: Manages small-scale processes like batch mixing (temperature/level control), water treatment skids, and HVAC units.
-
Building Automation: Integrates lighting, access control, and energy monitoring in smart factories or commercial buildings.
-
OEM Equipment: Embedded in original equipment manufacturer (OEM) machines for plug-and-play automation (e.g., medical device assembly stations).
