PLC Control Systems
In warehouse automation, Programmable Logic Controllers (PLCs) are rugged, high-performance devices that serve as the real-time control layer for mechanical systems like conveyors, sorters, carton erectors, and palletizers. They monitor inputs, execute programmed logic, and control outputs with millisecond precision - without relying on proprietary PC-based controls. PLCs also communicate with Warehouse Control Systems (WCS) and Warehouse Execution Systems (WES), enabling seamless coordination and providing real-time data and status updates.
Benefits of PLC-Based Controls & Recontrols
PLCs provide industrially hardened, high-performance control technology that is widely supported, scalable, and designed for 24/7 operations. With standardized architecture and strong interoperability across control devices and industrial protocols like Ethernet/IP, PLCs offer reliable, long-term automation control.
Trew uses PLC-based controls exclusively for conveyor and sortation systems, including high-rate merging, induction, and sortation. We build new systems using a PLC architecture, can also perform recontrols replacing aging PC-controlled systems. Transitioning to PLCs enhances reliability, supportability, long-term maintainability and provide the opportunity for centralized control and system visibility.
