Keeping the power on in critical facilities

Keeping the power on at critical facilities such as airports, hospitals and data centres is imperative, as a loss of power could compromise the lives of people and have a wide economic impact. Backup power systems must be designed, installed and regularly maintained in order to operate effectively, and having a properly engineered control system to monitor and manage the power system should be one of the highest priorities for owners and operators of critical infrastructure.

Is SCADA secure against cyber security threats?

Cyber security has become an increasingly important issue, with the control systems of critical infrastructure becoming a potential target of hackers. In the past, control systems were isolated from other networks, however modern systems are complex, digital and connected, with data required to be transferred between industrial and external networks. This creates a potential for malware and hackers to access and disrupt the system. While these threats are real, there are steps that can be taken to ensure control systems are more secure.

Putting out fires with Inertisation Units

If a fire breaks out in a mine it can cause death, disrupt and damage the local community, and depending on the circumstances, can burn for decades or even hundreds of years. Inertisation Units are important as they ensure fires are eliminated quickly, so it’s vital that they are working correctly. While not commonly utiliised, SCADA systems can allow for greater control of the unit and improve safety at the site.

Standardised control systems benefit water and wastewater facilities

Control system integration improves efficiency and ensures consistent operations at water and wastewater facilities. It is important when implementing these systems that they are standardised across the application as a mixed system can become increasingly unstable, preventing the site from operating efficiently or safely.

The importance of standards in automated systems

Choosing a control systems integration company that provides products and services that are compliant with relevant standards increases the quality of the automated system installed at a site. Standards ensure operation and maintenance of the plant and associated equipment is improved, with greater efficiency, safety and reliability.

What makes up a SCADA control system?

Supervisory Control and Data Acquisition (SCADA) systems are becoming increasingly essential across a variety of industries as a way for asset owners to maintain efficiency, process data for informed decision making, reduce costs, communicate issues to prevent downtime, and comply with relevant health and safety, and engineering standards. In this introductory article, we look at the different elements that make up a SCADA system.

RPEQ / Functional Safety Services

Automation IT has extensive experience in the design of control systems across a range of industries and applications. Our experience in industrial control systems has enabled us to provide a range of solutions to not only control machinery but also protect the machinery and its operators from unsafe situations or hazards.

If we look at a typical safety application in some detail, what we have essentially is a control system operating machinery via a set of hydraulic, electric or other controls with a series of monitoring devices and safety interlocks to ensure the safe motion of the object. The key items to note are the means of actuation, the personnel exposed to the machine and the requirements for safety interlocking. The failure of the control system could result in injury, possibly death and uncontrolled motion causing equipment downtime and machinery damage.
