PLC Programmer for Low Voltage Switchgear Panel Builder

1. Core Responsibilities

• System Design & Configuration:
• Collaborate with electrical engineers to design low-voltage control panels for industrial machinery, HVAC systems, or process automation.
• Configure PLCs (e.g., Siemens, Allen-Bradley, Mitsubishi) to interface with low-voltage components like relays, contactors, circuit breakers, and sensors.
• PLC Programming:
• Write, test, and debug PLC ladder logic, structured text, or function block diagrams (FBD) to control panel operations.
• Integrate safety systems (e.g., emergency stops, interlocks) compliant with standards like IEC 61131-3 or NFPA 79.
• HMI/SCADA Integration:
• Develop Human-Machine Interface (HMI) screens for operators to monitor and control low-voltage panel systems.
• Link PLCs to SCADA systems for centralized data acquisition and remote management.
• Testing & Commissioning:
• Simulate control logic using software tools (e.g., TIA Portal, RSLogix) before physical implementation.
• Conduct on-site testing to ensure panels meet functional and safety requirements.
• Troubleshooting & Maintenance:
• Diagnose and resolve faults in PLC programs or hardware (e.g., I/O module failures, communication errors).
• Update programs to accommodate system upgrades or process changes.

2. Low Voltage Panel-Specific Tasks

• Component Selection:
• Choose appropriate low-voltage devices (e.g., motor starters, timers, overload protectors) for panel assembly.
• Ensure compatibility between PLCs and panel components (e.g., 24V DC control circuits).
• Wiring & Documentation:
• Review electrical schematics and wiring diagrams to verify compliance with design specifications.
• Maintain detailed documentation of programs, panel layouts, and I/O lists.
• Safety Compliance:
• Adhere to standards like IEC 61439 (low-voltage switchgear) and local regulations (e.g., UAE Electricity Rules).
• Implement fail-safe logic to prevent electrical hazards (e.g., short circuits, overloads).
• Energy Efficiency:
• Optimize PLC logic to reduce energy consumption in low-voltage systems (e.g., motor control, lighting automation).

3. Collaboration & Communication

• Work with cross-functional teams (e.g., electricians, project managers) to ensure timely panel delivery.
• Train end-users or maintenance staff on operating PLC-controlled panels.
• Provide technical support during installation and post-commissioning phases.

4. Key Skills & Tools

• Technical Skills:
• Proficiency in PLC programming languages (Ladder Logic, Structured Text).
• Familiarity with low-voltage components (e.g., MCBs, contactors, VFDs).
• Knowledge of communication protocols (Modbus, Profibus, Ethernet/IP).
• Software/Tools:
• PLC IDEs (e.g., Siemens TIA Portal, Rockwell Studio 5000).
• CAD tools for electrical design (e.g., EPLAN, AutoCAD Electrical).
• Simulation tools (e.g., PLCSIM, FactoryTalk).
