Location: Kandivali (West), Mumbai

Employment Type:

Job Summary: The Siemens PLC and SCADA Programmer will lead the automation efforts for industrial projects. You will be responsible for writing logic for Siemens S7-series controllers and designing high-quality visualization interfaces (HMI/SCADA). Your goal is to create robust, modular, and scalable code that minimizes downtime and provides operators with intuitive control over complex processes. Candidate should be ready to travel on site for implementation and trouble shoot issues if required.

Key Responsibilities:

1. PLC Logic Development • Program Design: Develop and debug complex PLC code using TIA Portal or Step 7 Classic.

• Language Proficiency: Write logic in various IEC 61131-3 languages, primarily Ladder Logic (LAD), Function Block Diagram (FBD), and Structured Control Language (SCL).

• Modular Architecture: Create reusable Function Blocks (FBs) and Functions (FCs) using Data Blocks (DBs) for standardized project execution.

• Hardware Configuration: Select and configure Siemens hardware, including S7-1200, S7-1500, S7-300, and ET 200 distributed I/O systems.

2. SCADA & HMI Visualization

• Alarms & Trends: Configure alarm management systems and historical data logging (Trending) for process analysis.

• Scripting: Utilize C-Script or VBScript (and increasingly JavaScript for WinCC Unified) to handle complex background tasks and dynamic UI elements.

3. Networking & Integration :

• Industrial Protocols: Establish communication between PLCs, HMIs, and drives using PROFINET, PROFIBUS, and Modbus TCP/RTU.

• Drive Integration: Configure and commission Siemens SINAMICS VFDs (Variable Frequency Drives) via Start drive within TIA Portal.

• IIoT & Data: Interface the SCADA system with SQL databases or higher level MES/ERP systems for production reporting.

4. Testing & Commissioning:

• Simulation: Use PLCSIM and PLCSIM Advanced to validate logic in a virtual environment before on-site deployment.

• Field Commissioning: Perform on-site startup, including I/O checking, loop tuning (PID), and troubleshooting of electrical panels.

• Documentation: Maintain detailed "As-Built" documentation, I/O lists, and user manuals.

Soft Skills:

• Strong communication and interpersonal skills.

• Excellent problem-solving and analytical thinking.

• Ability to work collaboratively in a team environment.

• Customer-oriented mindset.
