For an internationally operating special machinery manufacturer, an experienced PLC programmer is sought to realize demanding automation projects. The focus is on reprogramming and commissioning controls.
- Typical tasks: development, testing, and documentation of PLC software for new systems with Siemens SIMATIC S7 (TIA Portal) and/or CODESYS V3. Creation and adjustment of HMI visualizations (e.g., with WinCC Unified, TwinCAT HMI). On-site commissioning of machines and systems at the customer (incl. I/O checks, fieldbus configuration such as Profinet/EtherCAT, functional tests). Systematic error analysis and optimization of existing systems. Technical support for customer service.
- Relevant technologies/tools: Siemens TIA Portal, SIMATIC S7-1500, CODESYS V3, Beckhoff TwinCAT, WinCC, various fieldbus configurators, EPLAN P8 (reading wiring diagrams).
- KPIs/success metrics: adherence to development and commissioning schedules, reduction of commissioning time through high software quality, machine cycle time and availability (OEE), customer satisfaction after commissioning.
- Special challenges: integration of hardware and software components from different manufacturers. Working under time pressure during on-site commissioning. Ensuring functional machine safety (Safety PLC) according to standards (e.g., ISO 13849-1).
- Deliverables: operational, fully documented PLC programs, final HMI projects, signed commissioning and acceptance protocols, creation or addition of operating manuals.
- Best practices: structured programming according to standards (e.g., IEC 61131-3), modular and reusable software blocks, consistent code versioning (e.g., in Git).
