CODESYS

Patrion’s field-service engineering team delivers hands-on implementation, commissioning, and lifecycle support for CODESYS-based automation projects. Leveraging the CODESYS Development System (CODESYS V3.5) and CODESYS Control runtime platforms, Patrion integrates IEC 61131-3 application code, SoftMotion multi-axis motion, Visualization HMI, and the CODESYS OPC UA Server into production systems across controllers from 400+ hardware vendors. Workstreams routinely include PLC application design in Structured Text (ST), Ladder (LD), FBD and SFC, motion programming using PLCopen motion libraries and CiA 402-compliant drive profiles, and HMI design with CODESYS Visualization for embedded and panel displays. On communications and integration, Patrion engineers build OPC UA (Server and PubSub) interfaces for MES/SCADA (mapping to ISA-95 work order and production models), implement Modbus TCP/RTU and MQTT gateways, and configure fieldbus masters for EtherCAT, PROFINET, CANopen and Ethernet/IP. For device lifecycle and remote management they deploy and manage CODESYS Automation Server for secure device provisioning, remote updates and version control, integrating Git-based code repositories and CI/CD where required. Commissioning and diagnostics services emphasize deterministic behavior and real-time tuning: Patrion configures CODESYS Control runtimes for target platforms (Windows softPLC, embedded Linux targets, and vendor controllers), sets task priorities and watchdogs, performs bus-level diagnostics and latency profiling, and tunes motion loops with encoder feedback and cam/interpolation profiles. All implementation work adheres to industry standards including IEC 61131-3 for control software, PLCopen for motion interfaces, and IEC 62443 cybersecurity practices for OT hardening. Patrion also supports safety-certified applications using CODESYS Safety modules and provides migration services from legacy PLC environments to CODESYS, including automated code conversion assessments, risk assessments per IEC 61508/ISO 13849 when functional safety is in scope, and Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) deliverables. Typical deliverables include source code with revision history, HMI screen libraries, OPC UA information models, commissioning reports, network diagrams, cybersecurity hardening checklists, and operator training. Patrion’s engineers execute on-site and remote assignments worldwide, offering rapid response for emergency troubleshooting, preventative maintenance, firmware and runtime upgrades, and long-term support agreements to minimize downtime and accelerate time-to-production.
