SIMATIC IT, now part of Opcenter, is a manufacturing execution system (MES) portfolio. SIMATIC IT MES addresses the growing need for overall production integration to ensure maximum quality and productivity across all global manufacturing facilities.


Adapting to the specific requirements of different industries and manufacturing approaches, SIMATIC IT includes manufacturing execution system solutions for discrete, process, and pharmaceutical industries, as well as integrated solutions for research, development, and laboratory (RD&L) management and manufacturing intelligence.

Highly dynamic markets and challenging performance demands make efficient manufacturing operations management (MOM) in integrated production plants a key factor for success. The best way to meet these demands is through a holistic and scalable approach to manufacturing operations management digitalization, and manufacturing execution technology is a primary pillar of a holistic manufacturing operations management solution. SIMATIC IT MES offers scalable, standards-based manufacturing execution, and quality assessment that results in higher manufacturing responsiveness. In sum, SIMATIC IT enables optimum productivity with high production quality at a lower cost.

SIMATIC IT MES functionality

Within a manufacturing operations management solution, SIMATIC IT MES provides key functionalities that enable real-time control of critical production operations through end-to-end visibility. Linking enterprise resource planning (ERP), product lifecycle management (PLM) and other enterprise systems to the shop floor, SIMATIC IT MES provides manufacturers with a real-time industry software layer that increases production visibility and responsiveness by executing production processes and managing production operations.

Critical to SIMATIC IT’s flexibility, each SIMATIC IT system is capable of adapting to the changing needs of each manufacturer through:

Scalability — SIMATIC IT systems are capable of adding greater capacity, including more users, more facilities and more transactions, as a manufacturer’s needs grow.

Extensibility— SIMATIC IT systems are capable of adding functionality, both in the form of additional modules and through “code-less extensibility,” which enables non-IT SIMATIC IT users to build applications customized to their specific needs.

Integration-readiness — SIMATIC IT systems may operate as standalone digital point solutions or may be integrated into a linked ecosystem of manufacturing IT functions including MOM, QMS, ERP, and PLM systems.

SIMATIC IT manufacturing execution systems support rapid, informed decisions in fast-changing operating environments. SIMATIC IT MES software functionality includes:

SIMATIC IT software


SIMATIC IT Unified Architecture Foundation (UAF) is a platform for building, running, and managing a modern MOM ecosystem, targeting the current and future transformational technologies that are shaping the future of manufacturing. At the core of SIMATIC IT UAF is a unified manufacturing operation data bus that provides a common backbone for the integration of legacy applications while also offering the first fundamental step towards a unified, integrated system.

SIMATIC IT UAF logics are executed in a distributed execution environment designed to run on small- to large-scale computing hardware. Data is persisted in a standard relational database management system (RDBMS).

SIMATIC IT UAF is constructed around domain-driven design (DDD). Application data, services, and events are defined by a model setting out application structure and exposed as metadata at any layer.

SIMATIC IT UAF features an event-driven service-oriented architecture (SOA). Its application is composed of modular functional blocks, deployed and managed by the execution environment, intercommunicating with events and messages. This architecture allows modular application management, thus facilitating functional expansion.

SIMATIC IT UAF is designed to scale up to ensure a high level of performance throughout the application lifecycle, supporting a growing load of users and data as well as expansion on a functional level.

SIMATIC IT R&D Suite streamlines R&D and manufacturing processes. It enables a seamless transition of product data and definitions through the entire manufacturing process by integrating R&D labs with plants.

SIMATIC IT R&D Suite keeps product designs and processes well in line with quality and regulatory requirements. It supports key functionalities like regulatory compliance and intellectual property processes. Typical R&D activities such as project management, formula and packaging development, trial and experiment management, and production process design are supported with an integrated set of best-in-class components, including electronic notebooks, laboratory management, specification management, batch and inventory management, pilot plant manufacturing, and more.

In its current form, SIMATIC R&D Suite bundles its capabilities into three integrated modular solutions for research, development, and lab activities:

  • SIMATIC IT Interspec (see Opcenter Specification) - Enables one single repository worldwide for overall plants, containing all details for all raw materials, semi-finished goods, finished goods, and packaging materials that have been used within a company. Includes full bill of material and version-controlled specifications.
  • SIMATIC IT R&D formulation components (see Opcenter Formulation) - Brings to life the digital twin of the product. Accesses the single repository provided by SIMATIC IT Interspec to work on an improved formula in a digital environment, starting from an existing bill of materials (BOM) or starting from scratch. Having the digital twin of the formula allows users to see the immediate impact of that formula on product cost, nutritional values, allergens, as well as regulatory compliance (including regulations anywhere the product is exported worldwide).
  • SIMATIC IT Unilab (see Opcenter Laboratory) - The laboratory information management system (LIMS) component is a fundamental part of the SIMATIC IT R&D Suite. Having defined all the quality parameters and specification management components, and having the digital twin of formula, SIMATIC IT Unilab allows the system to seamlessly transfer this digital twin into real-life trials and also to analyze immediately in the lab to see how these trials comply with the quality parameters that are set forward.

Other critical tools in SIMATIC IT R&D Suite include:

Electronic lab notebook (ELN)—Provides targeted functionality to ensure that every researcher has the full freedom to easily capture all data of any type of experiment or report in electronic format.

Formula workbench—Provides the creative environment to manage large numbers of prototypes in a workbench and supports trials and experiments to introduce and verify new formulas, raw materials, packaging materials, ingredients, manufacturing process designs, and test designs.

Supplier collaboration—This allows you to work closely with your suppliers on formulated product data management. Suppliers can directly access the system through a secured portal where they can only view the materials they are supplying and update the information fields needed. This tool minimizes the risk of errors and inefficiencies due to specifications missing on product data sheets or due to time lost in re-typing specifications into the system.
