Technical articles, tutorials and case studies written by engineers for engineers. Deep-dives into CODESYS, industrial hardware and embedded systems.
CODESYS
IEC 61131-3 defines the five PLC programming languages every industrial automation engineer should master. In this article we break down how to organise a real CODESYS project following best practices: POU structure, cyclic task management and robust error handling.

HardwareThe Deep Sea Electronics DSE7320 is one of the most complete generator controllers on the market. We analyse its configuration for backup installations in hospitals and data centres, including automatic transfer and remote monitoring.
OpenPAYGOComplete technical guide for implementing the OpenPAYGO token system in a microcontroller. We cover the generation algorithm, field credit management and communication with the licence server.
CODESYSModbus TCP remains the most widely used protocol on the factory floor. Learn to configure the Modbus TCP stack in CODESYS, manage registers efficiently and debug communication issues in production.
AutomationI/O count, scan cycle, protocol support, programming licence costs… We share the framework we use internally to evaluate and select PLCs in real industrial projects.
HardwareModbus RTU, CANopen, PROFIBUS, EtherNet/IP… When devices don't speak the same language you need a gateway. We analyse the key selection criteria and the most common integration mistakes.
OpenPAYGOPAYG systems are transforming energy access in emerging markets. We design the complete architecture here: metering hardware, embedded firmware, token server and customer management app.
TutorialDetailed tutorial with screenshots for configuring an EtherNet/IP network in CODESYS. We cover scanner definition, EDS import and reading adapter variables in real time.
CODESYSFunctional safety is non-negotiable in industrial machinery. We explain how to implement PLCopen safety function blocks in CODESYS Safety and what documentation you need for SIL2 certification.
