For an internationally active manufacturer of special machinery, an experienced PLC programmer is sought to implement demanding automation projects. The focus is on new programming and commissioning of control systems.
- Typical areas of responsibility: Development, testing and documentation of PLC software for new systems using Siemens SIMATIC S7 (TIA Portal) and/or CODESYS V3. Creation and adaptation of HMI visualizations (e.g., with WinCC Unified, TwinCAT HMI). Commissioning of machines and systems at the customer site (including I/O checks, configuration of fieldbus systems such as Profinet/EtherCAT, functional tests). Systematic troubleshooting 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 circuit 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 various 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 supplementing of operating manuals.
- Best practices: Structured programming according to standards (e.g., IEC 61131-3), modular and reusable software blocks, consistent version control of code (e.g., in Git).
