To meet such challenging goals, you can use Opcenter Execution Process for a new and innovative approach, leveraging the power of low code development powered by the Mendix™ app platform combined with the rich out-of-the-box (OOTB) set of MES data model and functional transactions for the CPG and process industries.
Opcenter Execution Pharma is a manufacturing execution system (MES) offering paperless manufacturing and electronic batch recording (eBR) of pharmaceuticals.
The Automation Gateway binds live PLC values directly to work order operations.
With seamless integration between Opcenter Execution and SAP ERP, ESTRA has achieved a consistent flow of information between business and production systems, resulting in improved operational efficiency and streamlined data management.
Our OEE management software monitors machine availability, performance and part failure/rejection rate. It calculates OEE and makes this information visible to all stakeholders.
For discrete manufacturing, an elastic MES supports serialized production, complex assemblies and detailed tracking of parts and subassemblies. For process and hybrid manufacturing software, it manages batch-driven workflows, material transformations and variable production paths.
Plex MES captures real-time production data at every step of the process, creating unique Lot IDs for raw materials, work-in-progress (WIP), and finished goods.
Plex MES Automation & Orchestration is a low-code solution that integrates manufacturing operations with the Plex MES to automate workflows and control information flow at the plant edge.
Our flexible, configurable cloud MES system is also easy to deploy, standardize across your enterprise, and connect to your corporate ERP.
Production monitoring software gives manufacturers real-time visibility into what’s happening on the plant floor by automatically capturing machine data, downtime and production performance.
MES-powered Industrial Operations Platform for manufacturers of discrete products with special focus on the following industries: Semiconductor, Electronics, Medical Devices and Industrial Equipment.
Genealogic simplifies this by leveraging MES data to provide seamless access to complete traceability and production history. With the interactive Graphical Genealogy Explorer, users can easily narrow or expand their search, connecting historical data across all related lots, components, and processes.
Two factors are necessary for a best-in-class MOM solution: global process flexibility and standardization. Flexibility is vital as processes must often be changed to reflect new market conditions, government regulations, or continuous improvement initiatives. Flexibility is also necessary to support multiple manufacturing modes—global manufacturing organizations typically have multiple divisions manufacturing many different types of products. This means global MOM platforms must support both discrete and batch processing, as well as hybrid modes. It also means supporting the spectrum from repetitive manufacturing to Make-To-Order or Engineer-To-Order. DELMIA Apriso supports each of these capabilities.
Track and trace genealogy of people, equipment, processes and materials throughout the production cycle.
DELMIA Apriso Machine Integrator provides a vital link to simplify management of the equipment layer. By automating real-time data collection with a distributed, bi-directional machine or process control connectivity, business processes can be integrated using common industry protocols.
It supports over 40 standard connection points with ERP, providing unmatched ERP integration.
Cloud-native from day one, Tulip’s architecture is designed to scale and is highly extensible – enabling companies to create technology stacks with connections with other systems and the physical world.
The platform captures a complete genealogy record for every item produced. It links the serial number to the operator, the machine, the specific tool readings, and the materials consumed, providing a complete digital history of the build.
Tulip's platform aligns with FDA 21 CFR Part 11 and EudraLex Annex 11 requirements for electronic records and signatures.
Communicate bi-directionally with your machines to automate machine set points. Connect via Node-RED, MQTT, and OPC UA directly or through Tulip’s edge devices.
Capture machine attributes by connecting Tulip to your OPC UA server or your MQTT broker with pre-built connectors to Highbyte, Litmus, HiveMQ, etc.
Tulip can integrate with SAP ECC with an HTTP Connector, but requires an intermediary middleware or integration layer (e.g. an iPaaS) since ECC doesn't expose native REST APIs.
Tulip lists ERP connector assets for NetSuite, SAP, Acumatica, and Oracle Fusion.
Track availability, performance, and quality in real time so you can act before the shift is lost.
