Manufacturing execution systems (MES) and supervisory control and data acquisition (SCADA) systems are both essential components of modern industrial operations. While they might seem similar at first glance, they serve distinct purposes and offer unique benefits.

Learn why an MES is necessary—even if you already have a SCADA system in place—and how integrating the two systems can lead to greater efficiency and productivity in your manufacturing processes. In this post we will also describe the value of MES, how it complements SCADA, and why Inductive Automation’s Ignition platform is the ideal choice for a seamless integration of both technologies.

SCADA Systems in Modern Manufacturing

SCADA systems have been providing centralized control and data acquisition for industrial processes for decades. Typically, they monitor and control equipment, collect real-time data, and manage alarms. These systems are crucial for maintaining operational efficiency and ensuring that equipment functions optimally. However, SCADA systems mainly focus on the process and equipment level of an operation. Fortunately, Manufacturing Execution Systems (MES) have the higher-level management and analysis capabilities.

SCADA Systems allow operators to execute the production needs of the business. It doesn’t tell operators what to make, when to make it, or how production efficiency impacts the bottom line of the company. If you were to compare manufacturing operations to going on a road trip, SCADA is the car. It gets you where you need to go, has dashboard indicators for the critical information you need to drive safely. You will also need to maintain the car as a whole to ensure it runs reliably for as long as you need it. Simply having a car won’t get you far on a road trip though, you need to think about where you want to go, how you are going to get there, schedule your drive time and stops along the way, and make sure you have all of the resources you need to get to your destination. That is where MES shines.

Why We Need MES Systems

Manufacturing Execution Systems (MES) are software solutions designed to bridge the gap between the shop floor and the enterprise, providing real-time data and visibility into production processes. They offer a range of features and benefits that go beyond SCADA systems. These systems include:

Production Planning and Scheduling

MES systems enable manufacturers to effectively plan, schedule, and optimize production processes. This can help minimize downtime, reduce waste, and improve overall production efficiency.

Quality Management

MES helps monitor and control the quality of products throughout the production process. By ensuring consistent product quality, MES systems can help reduce the costs associated with rework and recalls.

Real-Time Performance Metrics

MES systems provide real-time performance metrics, such as overall equipment effectiveness (OEE), which help manufacturers identify opportunities for improvement and to optimize their operations.

Traceability and Compliance

MES solutions support product and materials traceability throughout the manufacturing process. Traceability is essential for industries with strict regulatory requirements, such as pharmaceuticals and food and beverage.

Integration with Enterprise Systems

MES systems are designed to integrate with other enterprise systems, such as ERP, PLM, and CRM, providing a seamless flow of information across the organization and enabling better business decision-making.

The Value of Integrating MES and SCADA

Integrating MES and SCADA systems can result in significant improvements in manufacturing operations. The combination of the two systems allows for real-time data collection and analysis, enabling manufacturers to make informed decisions quickly and effectively. Some of the key benefits of integrating MES and SCADA include:

Enhanced Operational Visibility

Combining the data from both MES and SCADA systems provides a comprehensive view of the entire manufacturing process, from equipment performance to product quality. This increased visibility allows for more informed decision-making and improved operational efficiency.

Improved Decision-Making

With MES and SCADA systems working together, manufacturers can access real-time data and insights to make better decisions, faster. This can lead to improved productivity, reduced downtime, and increased profitability.

Streamlined Operations

Integrating MES and SCADA systems can help automate and streamline processes, reducing manual intervention and the potential for human error. This can result in more efficient and reliable production processes, ultimately improving overall operational efficiency.

Greater Flexibility

By connecting MES and SCADA systems, manufacturers can more easily adapt to changes in production requirements or market conditions. This increased flexibility can help manufacturers stay competitive in an ever-evolving industry landscape.

Ignition for MES and SCADA Integration

Ignition by Inductive Automation is a powerful, versatile, and increasingly popular industrial application platform. Its ability to seamlessly integrate MES and SCADA systems is one of the main reasons for its popularity. Ignition’s modular architecture offers a range of advantages for manufacturers looking to enhance their operations.

1. Scalability: Ignition's modular architecture allows for easy scalability, enabling manufacturers to grow and expand their systems as needed without significant infrastructure investments.

2. Cross-Platform Compatibility: Ignition is platform-agnostic, meaning it can be deployed on any operating system, including Windows, macOS, and Linux. This flexibility ensures seamless integration with existing systems and simplifies IT management.

3. Web-Based Deployment: Ignition's web-based deployment allows users to access and manage their MES and SCADA systems from any device with a web browser, providing increased mobility and ease of use.

4. Robust Security: Ignition offers robust security features to protect your data and systems, including SSL/TLS encryption, multi-factor authentication, and role-based access control.

5. Rapid Development and Customization: Ignition's intuitive design tools and scripting support enable rapid development and customization of applications to suit your specific needs.

6. Extensive Module Library: Ignition offers a wide range of modules that can be easily integrated into your MES and SCADA systems, including modules for OEE, SPC, recipe management, and more.

SCADA + MES = Optimized Operations

While SCADA systems are crucial for monitoring and controlling equipment in industrial processes, they lack the higher-level management and analysis capabilities of MES systems. Integrating MES and SCADA systems can lead to significant improvements in manufacturing operations by providing real-time data collection and analysis, enhanced visibility, streamlined operations, and greater flexibility.

The Ignition platform by Inductive Automation is an ideal choice for integrating MES and SCADA systems, offering a range of benefits such as scalability, cross-platform compatibility, web-based deployment, robust security, and rapid development capabilities. By choosing Ignition, manufacturers can harness the power of both MES and SCADA to drive operational efficiency, improve decision-making, and ultimately increase profitability.
