SCADA, Instrumentation & Automation Solutions

At NEC, we deliver end-to-end automation, control, and monitoring solutions tailored for the demanding environments of the construction and oil & gas industries. From SCADA systems and instrumentation to PLC programming, system integration, and Building Management Systems (BMS), our services are designed to optimize performance, safety, and efficiency across all project phases.

SCADA Systems

We provide advanced SCADA solutions based on trusted platforms such as Siemens SIMATIC WinCC and PCS 7, enabling real-time monitoring and control of field operations. Our systems support secure remote access, custom HMI development, alarm/event management, and integration with a wide range of sensors and control devices.

Applications:

Oil & gas wellheads, pipelines, terminals, compressors

Construction site utilities, temporary substations, and generators

Remote monitoring of tank levels, energy meters, HVAC, and lighting

Instrumentation

We specialize in the design, supply, installation, and calibration of field instrumentation for process and utility monitoring. Our team ensures accurate measurement and control of flow, pressure, temperature, level, and vibration — critical for safe and efficient operations.

Capabilities:

Selection and integration of smart field instruments (Siemens, Endress+Hauser, Yokogawa, etc.)

Hazardous area instrumentation for oil & gas environments

Calibration and commissioning services

Signal conditioning and interface to PLC/SCADA systems

PLC Programming

Our engineers are proficient in PLC programming, logic development, and troubleshooting for a wide range of Siemens controllers, including S7-1200, S7-1500, S7-300/400, and TIA Portal.

Key Services:

Custom logic design and interlock sequencing

Safety PLC configurations and fail-safe systems

PID control loops and analog signal processing

Communication with HMIs, RTUs, and SCADA

System Integration

We offer full system integration services to unify electrical, automation, and mechanical systems into a single, efficient control environment. We ensure smooth interoperability between equipment from multiple vendors and deliver plug-and-play solutions that reduce commissioning time.
