The REXRTOH PIC-6115 is a central component within the IndraControl family of automation solutions, representing a sophisticated Programmable Industrial Controller designed to meet the complex demands of modern machinery. It transcends the role of a standard PLC by integrating high-speed logic processing with deterministic motion control capabilities in a single, cohesive unit. This convergence allows machine builders to streamline control architecture, reduce component count, and achieve tighter synchronization between discrete I/O operations and multi-axis motion sequences, making it a preferred choice for high-performance automated systems.
The PIC-6115 functions as the central brain of an automation system. Its primary role is to execute a user-defined control program that manages all machine functions—from reading sensor inputs and controlling actuators to executing complex motion profiles for servo drives. Unlike systems where a separate PLC and motion controller communicate over a network, the PIC-6115 internally handles both logic and motion tasks. This eliminates communication delays, ensures deterministic execution, and provides a unified programming and diagnostic environment for the entire machine, from simple pneumatic sequences to coordinated multi-axis interpolated moves.
The PIC-6115 is engineered with a suite of features that define its performance and integration potential:
Powerful Processing Unit: Equipped with a high-performance CPU capable of executing complex logic and motion control algorithms with fast cycle times, ensuring responsiveness for dynamic applications.
Integrated Motion Control: Natively supports motion control function blocks (following PLCopen standards) for controlling multiple servo axes, including functions for positioning, gearing, camming, and pressure/force control.
Direct Drive Connectivity: Features built-in interfaces, such as SERCOS III or EtherCAT, for deterministic, real-time communication with Rexroth and third-party servo drives, enabling precise synchronized motion.
Comprehensive I/O and Communication: Offers multiple standard fieldbus (PROFIBUS, PROFINET, Ethernet/IP) and serial ports for connecting distributed I/O stations, HMIs, and higher-level supervisory systems (SCADA, MES).
Ample Memory and Storage: Provides sufficient user memory for large control programs and data storage for recipes, trace data, and event logging.
Unified Engineering Environment: Programmed and configured using Rexroth's IndraWorks engineering suite, which offers integrated tools for logic programming (IEC 61131-3 languages), motion configuration, drive parameterization, and system diagnostics.
Robust Industrial Design: Housed in a rugged enclosure designed for reliable operation in industrial environments with typical levels of electrical noise, vibration, and temperature variation.

The table below outlines the principal technical characteristics associated with the PIC-6115 controller.
In a typical machine architecture, the PIC-6115 is installed in the main control cabinet. It connects directly to servo drives via its real-time network, to distributed I/O blocks via a fieldbus, and to an operator panel via Ethernet. This setup creates a cohesive control pyramid. The controller executes a centralized program where motion commands (e.g., move axis A to position X) and logic conditions (e.g., start conveyor when part is present) are processed in a tightly synchronized manner. This is particularly critical for machines where mechanical actions must be perfectly timed with process events, such as in flying shears, rotary transfer machines, or synchronous assembly stations.
The PIC-6115 is ideally suited for complex machinery requiring synchronized logic and motion:
Packaging Machinery: Controlling form-fill-seal machines, cartoners, and labeling systems with synchronized product handling and tooling motions.
Assembly Automation: Coordinating robots, presses, and feeding systems in automated assembly and testing lines.
Machine Tools: Managing auxiliary axes, tool changers, and workpiece handling in conjunction with the main CNC system.
Material Handling: Controlling complex conveyor systems, sortation units, and palletizing/depalletizing cells.
Printing and Converting: Providing registration control, tension management, and cut-to-length functions on web-based equipment.
Plastics Processing: Coordinating mold movements, robot extractors, and peripheral equipment in injection molding cells.
The REXRTOH PIC-6115 Programmable Industrial Controller stands as a robust and intelligent platform for unified machine control. By seamlessly integrating high-performance PLC functionality with deterministic motion control within a single hardware unit and software environment, it simplifies system design, enhances performance, and improves reliability. For engineers developing advanced machinery where precision, speed, and synchronization are paramount, the PIC-6115 offers a powerful and efficient solution to meet the evolving challenges of industrial automation.
