CODESYS SCADA & HMI Development

Engineering Service delivers focused CODESYS SCADA & HMI development for industrial control applications using the CODESYS V3 platform and associated toolchain. The firm provides end-to-end engineering: requirements capture, IEC 61131-3-compliant software architecture, HMI visualization, communications integration, simulation, FAT/SAT support, and lifecycle maintenance. Typical technologies used include CODESYS Development System, CODESYS Control Runtime, CODESYS Visualization (WebVisu and Visualization SL), CODESYS OPC UA Server/Client, CODESYS Automation Server for device management, and CODESYS SoftMotion for coordinated motion on EtherCAT networks. Engineering Service engineers structure applications to ISA-88 and ISA-95 batch/recipe and MES integration patterns and implement IEC 61131-3 languages (ST, FBD, LD) with modular PLCopen and function-block design. Communications are handled via OPC UA, Modbus TCP/RTU, EtherNet/IP, PROFINET, EtherCAT, CANopen and MQTT for IIoT publishing. Security and hardening follow IEC 62443 guidance: role-based access, TLS for OPC UA, secure boot where supported, and network segmentation for OT/IT boundary control. Deliverables include a formal functional specification, I/O list, HMI screen matrix, alarm and event strategy per ISA 18.2, test protocols, and traceable FAT/SAT reports. The engineering group uses CODESYS Control Win and Hardware-in-the-Loop (HIL) for virtual commissioning and pre-site performance validation, and integrates version control (Git) and automated unit testing where applicable to accelerate commissioning risk reduction. On-site services cover hardware I/O checkout, control tuning, HMI usability refinement, alarm rationalization, and performance optimization to achieve deterministic scan and cycle targets. Engineering Service conducts FAT execution with scripted test cases and acceptance criteria, followed by SAT and operator training using hands-on labs. For long-term support, the firm offers remote diagnostics via CODESYS Automation Server, patch management, lifecycle updates, and spare-part recommendations. Projects span discrete manufacturing, packaging, water/wastewater, and material handling where deterministic communications and high-availability HMIs are required. Engineering Service’s approach emphasizes maintainable code, documented interfaces for MES/ERP handshakes, and measurable KPIs for safety, availability, and maintainability. Plant managers and procurement teams receive clear scope, milestone-based billing, and compliance evidence against IEC, ISA, and industry best practices.
