Information Requirements to Develop an MES (Manufacturing Execution Systems)

Regarding the information requirements and/or specifications that are needed to size and determine the scope of an automation project to implement an MES, it must be defined if the application and/or industry requires the following.

Indispensable Features:

  1. Compliance with the ISA-95 standard applicable to the Information Interaction for Manufacturing from the Floor to the ERP through the MES.
  2. Compliance with FDA/cGAMP5/CFR21-Part 11 & NOM-059.
  3. Interactive Analysis Tools.
  4. Personal Information Panels.

Data Required to Determine the Functional Scope of the MES Production System.

Scheduling.- Planning and Monitoring of the Production in Real Time WIP (Work In Process)

OEE Downtime (OEE-DT).- (Overall Equipment Effectiveness  – Down Time). Real time Production Efficiency Monitoring.

Track & Trace.- Registration and Tracking. Genealogical tree to track and record Finished, Semi/finished, Raw Material, Operators, Equipment, Cells, Lines, and more, for the EBR (Electronic Batch Record).

SPC (Statistical Process Control).- Collect and Monitor Data for Statistical Process Control.

Recipe / Changeover.- Manage and Monitor Recipes and Format Changes.

MES Enterprise Module.- Analysis of Production Data and Centralized Reports for Multiple Plants and Production Lines.

Instrument Interface.- Acquire and Decode data of Scales, Gauges, Analyzers, Laboratory Equipment, and more.

Visual Web Service.- Communicates other systems such as ERPs, LABs, WMS and others that use Web services.


The MES Traking Points, support tracking data for any combination of MES modules including Track & Trace, OEE Downtime, SPC y Recipe. Any data that needs to be tracked requires an MES Tracking Point and represents a physical or virtual machine, storage location, work cell, production lie, work station, etc.

                Examples of what an MES Tracking Point requires:

  1. OEE o DT for a line
  2. OEE o DT for a single-line machine
  3. Data for SPC in a storage silo
  4. Track & Trace in a collection site
  5. Recipe in a machine
  6. Track & Trace in a production line
  7. Track & Trace in a work cell
  8. OEE, SPC y Track & Trace in one line
  9. Track & Trace y SPC in a silo
  10. Track & Trace in a warehouse storage location

​ With the above we can indentify-qualify and quantify the number of MES Tracking Point


Data Required to Determine the Size of the Production MES


  1. Number of Physical Work Cells
  2. Number of Virtula Work Cells
  3. Number of Production Lines
  4. Types of Production Equipment
  5. Number of Production Equipment by Type
  6. Types of Operators by Product/Cell/Line/Plant
  7. Number of Operators by Product/Cell/Line/Plant
  8. Number of Users of the MES System
  9. Model/Brand/Specifications of the controller(s) of the cell(s)/ Production Line(s)
  10. Plant diagram (layout) with ID of Cells/Equipment/Lines/Plants
  11. Communications Network Architecture: Means and Protocols (physical-software) within the Plant
  12. Type of Products
  13. Number of Products
  14. Number of Product Formats
  15. Number of Recipes
  16. Customizations (conenections, screens, special functions)
