Testing and Commissioning: Ultimate Assurance
Providing end-to-end services for Operational Technology, from concept to completion
Zealinx specializes in providing industrial automation solutions for operational technology, focusing on Testing and Commissioning to ensure every system operates flawlessly. We specialize in three key areas:
Control Device Programming
Our experts excel in developing and implementing control device programs that are specifically tailored to your unique requirements. Whether it's a programmable logic controller (PLC) or a numerical relay-IED, our Testing and Commissioning processes ensure the smooth operation and control of your facility. With our customized programming solutions, you can optimize the performance and functionality of your equipment, allowing for seamless operations.
HMI Design & Implementation
We understand the importance of having a user-friendly and intuitive Human-Machine Interface (HMI) in your industrial setting. That’s why we offer Testing and Commissioning services alongside customized HMI design and implementation services. Our team will work closely with you to create a seamless interaction between humans and machines, resulting in improved productivity and reduced human error. With our expertise in HMI design, you can enhance the overall user experience and streamline operations within your facility.
SCADA System Integration
In today's interconnected world, it's crucial to have integrated systems that facilitate the smooth operation of various components within an industrial setting. Our team specializes in system integration, with a strong focus on Testing and Commissioning, allowing you to seamlessly connect different OT systems at your site. Whether it's integrating PLCs, HMIs, or other devices, we ensure that all components work together harmoniously, optimizing the overall performance of your facility.

Control Device Programming
Programmable Logic Controllers (PLCs) are essential components in manufacturing and industrial automation. They function as industrial computers with multiple inputs and outputs, allowing engineers and technicians to efficiently control and monitor complex industrial processes. Our Testing and Commissioning services ensure these systems operate at peak efficiency. PLCs are particularly advantageous because their internal timers, sequencers, and relays operate at a much faster speed than conventional time-delay relay systems. This makes them highly suitable for effectively managing assembly lines.
The numerical relay configuration in substations is another critical aspect of industrial control systems where our Testing and Commissioning guarantees reliability and safety. Numerical relays act as protective devices, specifically designed to safeguard power systems such as generators, motors, transformers, and lines. Utilizing microprocessors, these relays determine various parameters such as power flow direction, fault presence, and fault type.
Both PLC programming in manufacturing and numerical relay configuration in substations play vital roles in ensuring efficient operations, protecting crucial equipment, and maintaining safety within industrial settings.
HMI Design & Implementation
Human Machine Interface (HMI) design and implementation is a critical aspect of industrial automation systems. It bridges the gap between operators and the automation system, allowing for efficient interaction and control. Our Testing and Commissioning process, begins by understanding the client's specific needs, the complexity of their processes, and their operational goals. This includes evaluating the current system, identifying areas for improvement, and defining the desired functionalities of the HMI. The HMI is designed with user-friendliness as a priority. ensuring that the design is intuitive, easy-to-navigate, and visually appealing. The design also takes into account safety standards and guidelines.
Team of engineers and technicians will then implement the HMI solution, integrating it with the existing PLCs and other components of the automation system. This could involve writing necessary scripts or codes, configuring the system, and testing to ensure everything works seamlessly. We provides comprehensive training to the operators, ensuring they can effectively use the HMI. This includes demonstrating how to monitor processes, adjust parameters, diagnose issues, and perform other tasks.
After implementation, ongoing support and maintenance services. This includes regular system checks, software updates, troubleshooting, and repairs as needed. The ultimate goal in HMI design and implementation service, supported by Testing and Commissioning is to enhance operational efficiency, reduce downtime, and improve safety in the client's facility.


SCADA System Integration
SCADA and DCS are two types of industrial control systems used in various industries for process automation. SCADA systems are centralized and can monitor and control large areas or complex systems. They gather information, analyze it, and alert the necessary parties. Key components of a SCADA system include Human-Machine Interface, Remote Terminal Units, Programmable Logic Controller, and various communication methods.
On the other hand, DCS refers to a distributed control system where the controller elements are spread throughout the system. It is commonly used in industries like chemical plants and power generation. Key components of a DCS include input/output devices, controllers, networks, and operator stations.
Our solution ensures that maintenance personnel are promptly notified of critical alarms, even outside of working hours. This allows for unattended plant operations and substantial savings on labor costs for our customers. We have extensive experience with industry-leading vendors in areas such as communications network design, hardware and software specification, system design standards, and security policies and procedures.
Our expertise also extends to network cabinet, RTU, and control panel design and fabrication. In addition, we provide SCADA software configuration for tags, alarms, graphics, trends, and reports with seamless communication and integration with external systems. We also offer field Testing and Commissioning services, along with comprehensive training, to support our customers throughout the entire automation process.
By focusing on Testing and Commissioning, we ensure that all systems work together harmoniously, optimizing overall performance and reliability.
