Human Machine Interfaces (HMIs) is a graphical based visualization of an industrial control system, which in the old days was accomplished through lighting panels or an array of LEDs. Several businesses have started migrating towards HMIs in order to facilitate the workforce and provide more accurate & timely readings, however some choose to stay with the age-old solution of indicator lights, and for good reason.
Your PLC, contractors, relays, safety systems, and every other piece of control hardware requires a safe & secure home for proper, uninterrupted operation. Specification of control enclosure is a process that requires consideration of several requirements from physical size to environmental ratings to thermal thresholds. A step by step approach is therefore well-suited to ensure all the required boxes have been checked.
Industrial environments are volatile. Things can go wrong within minutes or stay stable for months. Nonetheless, ample protection is necessary to make sure things keep going as smoothly as possible. Enclosures are vital for any industry as they provide a housing for all cables, electrical equipment and termination points.
Nowadays, industries are getting increasingly digitized, so additional equipment is required that serves as a gateway to manual controls. Enclosures also provide due protection against RF waves as well as from environmental factors such as moisture, sunlight, etc. Plant managers in oil, gas, material handling, and virtually any industry are therefore keen to make sure all their equipment is safe as break in operations can result in lost time, resources and reputation.
A glance at the screen should be enough to provide your operators with enough information to carry out a targeted industrial operation. All the potential problems should be clearly indicated and any risks or faults should be highlighted as a top priority. A well-built HMI/SCADA system should be able to accomplish these tasks, and many more, including:
- Leveraging your HMI/SCADA as the base of all operations
- Driving the right & most efficient response in the face of alarms
- Instill consistency and conformity to standards
- Provide quick, on-demand support
Today, SCADA systems aren’t installed for providing monitoring & visualization of a certain process, with alarms rolling in. A well-built SCADA system should serve as a decision support system, enabling personnel to quickly manage resources and rectify faults.
