Data model
Sources, formats, record meaning, direction of flow and required update times.
Production data
PLC integration with databases, MES and ERP
We connect the control layer with external systems so that process data can be recorded, analysed and used in production management.
PLC and SCADAData from control and visualisation systems

MES and ERPProduction management system exchange
Service scope
A consistent information flow between production and business
We begin by identifying which data is needed, which system owns it and what should happen when communication is unavailable. The architecture and interface are selected only after these responsibilities are clear.
- Process values and event logging
- PLC and SCADA data exchange
- Connection to external databases
- Orders, recipes and status exchange
- MES and ERP system integration
- Data for reporting, analysis and traceability
Architecture
A solution designed for communication interruptions
The design covers update frequency, data validation, buffering, retries and clear fault handling. The objective is to protect production from an uncontrolled dependency on a higher-level system.
Interface
Communication method, acknowledgement, validation and behaviour after a connection loss.
End-to-end tests
Normal scenarios, invalid data, communication interruptions and recovery.
Applications
Data that supports practical decisions
Production reporting
Quantities, cycle times, stops, alarms and other information derived from the process.
Traceability
Links between a product, order or batch and the parameters and results of its process.
Recipe management
Controlled delivery of parameters to a machine with confirmation that they were applied.
MES and ERP cooperation
Orders, completion states, material consumption and production result exchange.
FAQ
Common questions
Should a PLC connect directly to a database?
It depends on the controller, communication mechanisms and process requirements. An intermediate layer is often safer because it can buffer data, validate messages and separate automation from business systems.
What happens when the connection is lost?
The required behaviour is agreed during design. The system may buffer data, flag missing confirmation, retry transmission and notify operators without stopping production when the process permits it.
Can you integrate with an existing MES or ERP?
Yes, when an agreed data interface is available. The project requires interface documentation, the record scope and a responsible contact for the customer's system or its supplier.
