The SIGMATEK DNC115 is a compact, high-performance programmable logic controller (PLC) from SIGMATEK’s Dali series, designed for small to mid-sized automation tasks in industrial machinery, packaging lines, conveyor systems, and process control applications. Built on a real-time Linux operating system, the DNC115 combines deterministic control performance with modern communication capabilities, offering a powerful yet cost-effective solution for machine builders seeking flexibility without complexity.
Housed in a space-saving DIN-rail enclosure, the SIGMATEK DNC115 integrates a 32-bit ARM processor, onboard digital I/O (8 inputs / 4 outputs), multiple communication interfaces—including Ethernet, RS485, and CANopen—and supports all five IEC 61131-3 programming languages (Ladder Diagram, Structured Text, Function Block Diagram, etc.) via SIGMATEK’s Automation Studio engineering platform. Its built-in web server enables remote monitoring and diagnostics via standard browsers, while optional SD card support allows for data logging, recipe management, and firmware updates in the field.
Designed for reliability, the DNC115 operates across a wide temperature range (-25°C to +60°C), features surge protection on I/O lines, and supports modular expansion through SIGMATEK’s decentralized I/O system—making it scalable from simple standalone machines to networked multi-axis systems.

Main Features and Advantages
✅ Integrated Multi-Protocol Communication
The DNC115 eliminates the need for external gateways by natively supporting Ethernet (Modbus TCP), RS485 (Modbus RTU), and CANopen—enabling seamless integration with HMIs, drives, sensors, and higher-level SCADA systems. The built-in CANopen interface can operate as either master or slave, ideal for motion coordination in multi-axis applications.
✅ Real-Time Performance with Linux Flexibility
Unlike traditional PLCs running proprietary OSes, the DNC115 leverages a hardened real-time Linux kernel, offering both deterministic scan cycles and advanced features like file system access, web services, and remote SSH—without compromising reliability.
✅ Compact Yet Expandable Architecture
Despite its small footprint (approx. 90 x 90 x 60 mm), the DNC115 can be expanded using SIGMATEK’s remote I/O modules over CANopen, supporting hundreds of additional I/O points. This makes it suitable for both standalone machines and distributed control topologies.
✅ User-Friendly Engineering & Diagnostics
Programmed entirely within SIGMATEK Automation Studio, the DNC115 benefits from intuitive debugging, online change capability, and integrated HMI design. The built-in web server displays I/O status, error logs, and system info—accessible from any smartphone or PC on the network.
✅ Robust for Industrial Environments
With wide voltage tolerance, ESD/surge protection, and extended temperature operation, the DNC115 performs reliably in electrically noisy or thermally challenging settings—common in food processing, woodworking, and material handling.
