Software

In the evolving landscape of Industry 4.0, seamless integration and data flow across machines, controllers, and enterprise systems are essential. Communication protocols form the backbone of such intelligent, connected systems. Our approach is centered around leveraging widely adopted and emerging industrial communication protocols to ensure:

• Interoperability between diverse equipment from different manufacturers
• Real-time data acquisition for production tracking and process optimization
• Secure and scalable connectivity to support modern MES, SCADA, and AI-driven analytics

We integrate protocols such as MODBUS TCP, Ethernet TCP/IP, Serial (RS232/USB), OPC UA, PROFINET, RS485 and HTTP-based RESTful interfaces — tailored for both legacy systems and modern automation frameworks.

Each protocol is selected based on:

• Machine/PLC compatibility
• Communication latency & bandwidth requirements
• Network topology and system architecture
• Security and scalability needs

Project Implementation on

MODBUS TCP

MODBUS TCP is implemented to facilitate communication with legacy PLCs and I/O devices commonly used in process and utility automation.

• Supports polling of registers from devices like Cobot, Vision Device, VFDs, sensors, and flow meters
• Enables real-time monitoring of production lines
• Integrated using Python/C++ libraries and optimized for multi-threaded socket communication
• Exception handling and retry mechanisms for robust uptime

Ethernet TCP/IP

Ethernet TCP/IP forms the primary transport layer for all controller-to-server and peer-to-peer communication.

• Used for high-speed communication between SCADA ↔ PLC, PC ↔ Printer, PC ↔ Vision device
• Integrated with socket-based or API interfaces to ensure vendor-independent communication
• Integrated with OEM MES

Serial (RS232 / USB)

Serial communication is still vital for certain low-cost or legacy instruments.

• Implementation includes RS232 over USB converters for compatibility
• Used in barcode scanners, label printers, liquid lenses, and conveyor-based PLC systems
• Managed with non-blocking threaded serial handlers in Python/C++

HTTP (REST APIs)

Modern systems use HTTP-based APIs to integrate with cloud dashboards, AI services, and mobile apps

• Stateless, scalable, and firewall-friendly interface
• JSON-based payloads for structured data exchange
• Supports asynchronous event posting, reporting, and status dashboards
• Secured with token-based authentication and audit trails

OPC UA (Open Platform Communications – Unified Architecture)

A platform-independent, service-oriented protocol for secure and scalable industrial communication.

• Enables semantic data modeling and standardized communication
• Integrated using Python libraries or industrial OPC UA clients
• Supports real-time PLC data acquisition and secure role-based access
• Used for a real-time vehicle spec display system from the conveyor PLC

PROFINET

PROFINET is a real-time Ethernet standard used in high-speed automation.

• Integrated for time-critical applications like robot coordination or sensor feedback
• Achieves cycle times <1ms, ideal for closed-loop controls
• Communicates with Siemens S7 PLCs and field devices
• Configured via TIA Portal (v16) and interfaced through PC-based runtime stacks

RS-485

RS-485 is a robust serial communication standard widely used in industrial environments for reliable long-distance and multi-point data exchange.

• Enabled vision-guided panel picking guidance using industrial cameras and image processing. The coordinate corrections were communicated over RS-485 to the Hyundai robot for fine-tuned path adjustments

Human-Machine Interfaces (HMIs) play a pivotal role in industrial automation by offering intuitive control, real-time visibility, and seamless communication with underlying devices such as PLCs, collaborative robots (cobots), barcode scanners, and sensor networks.

A well-designed HMI not only enhances operator efficiency but also enables real-time diagnostics, process adaptability, and data-driven decision-making.

Our HMI solutions are tailored for diverse industrial applications and support integration over OPC UA, Modbus TCP/IP, Ethernet/IP, and Profinet, ensuring compatibility with both legacy and modern systems. We offer both OEM-integrated HMI panels and custom-built, browser-based dashboards for high flexibility and scalability.
