Sommaire

What Is a MES?

A Manufacturing Execution System (MES) is the software layer that manages and monitors the transformation of raw materials into finished goods on the factory floor. It sits between your ERP (SAP, Oracle) at the top and your SCADA/PLC control systems at the bottom, receiving production orders from above and real-time machine data from below.

What Does a MES Do?

Work order management, schedules and dispatches production orders to the shop floor
Production tracking, monitors real-time progress of each batch or job
Quality management, enforces inspection points, records QC results, flags non-conformance
Materials tracking, tracks raw material consumption and WIP inventory
Labour tracking, records operator time against production orders
OEE calculation, measures availability, performance, and quality in real time
Genealogy and traceability, records what went into every product for compliance and recall management

MES vs ERP vs SCADA

System	Focus	Time Horizon
ERP	Business planning, finance, supply chain	Days to months
MES	Shop floor execution and tracking	Hours to days
SCADA	Machine monitoring and control	Seconds to minutes

MES Hardware Requirements

MES workstations on the shop floor need rugged, industrial-grade hardware. Key requirements include fanless Panel PCs with IP65 front panels to survive wash-downs, wide-format touchscreens for operator input, and COM ports for barcode scanner and label printer connectivity. TSL Automation's Avalue Panel PCs are ideal for MES operator stations across Indian manufacturing plants.

A Manufacturing Execution System (MES) is software that manages and controls manufacturing operations on the factory floor in real time, bridging the gap between ERP (business planning) and actual production. MES handles production order management, work instructions, material tracking, quality data collection, OEE calculation, genealogy and traceability, and reporting. It provides real-time visibility into what is happening on the shop floor.

SCADA monitors and controls physical processes, reading sensor data from machines, controlling setpoints, and logging process parameters. MES manages production operations, tracking work orders, materials, quality, labour, and OEE from a business process perspective. They are complementary: SCADA provides machine-level data that MES aggregates into production performance metrics. Many modern systems integrate SCADA data feeds directly into the MES historian.

MES hardware includes: an MES application server (industrial PC or server with appropriate CPU and RAM for the tag count and user load), industrial Panel PCs or ruggedised terminals at each workstation for operator interaction, barcode scanners and label printers for work order and material tracking, and network infrastructure connecting all stations. The MES server can be on-premises (industrial server in the factory) or cloud-hosted.

Common MES platforms used in Indian manufacturing include: SAP ME/MII (for SAP ERP environments), Siemens SIMATIC IT, Rockwell FactoryTalk ProductionCentre, Wonderware (AVEVA) MES, and various Indian-developed MES solutions for SME manufacturers. Selection depends on your ERP system, industry (automotive, pharma, FMCG), and existing SCADA/PLC infrastructure.
