I develop efficient, robust, and well-documented PLC and HMI applications using Siemens TIA Portal and Step7 Classic.My expertise includes both new projects and modifications to existing systems, with deep experience in S7-1500, S7-300, and legacy S7-300/400 systems programmed in Step7 Classic.
I cover full project lifecycles or specific tasks such as:
Logic design and programming (LAD, FBD, SCL, and Graph7 for sequential control)
HMI integration (WinCC Comfort and Unified)
Safety applications (FailSafe PLCs)
Communication: Profinet, Profibus, OPC UA
Integration of Sinamics S120 (multi-axis, without Simotion)
Retrofitting, troubleshooting, and online modifications
Barcode readers, printers, traceability systems
Remote support and technical documentation
Typical clients: Automotive, production machinery, custom equipment, traceability systems, and retrofit projects.
