available that meet the functional demands of these deployments such as reliability and interoperability that enables asset owners to lower the total cost of ownership. Flexible installation, limited spaces One of the key features for elevator deployments or retrofits is that components can fit into almost any control cabinet. However, it is not only the size of the control cabinet that restricts the type of component that can be deployed. Cabinets often have devices installed inside that don’t support flexible mounting. This means that these devices have to be installed in a specific place in the cabinet or extra wiring will be required, which can be challenging to achieve and incurs additional expense. If new components need to be added at a later date, components that support flexible mounting have a much better chance of being able to fit inside the cabinet. Unified data communication Another feature that assists elevator operators is to increase interoperability between all of the components that are found within elevators. Furthermore, if the integration of all the components can be automated, and no complicated settings need to be configured, this will ensure smoother operations. If a component supports all of the protocols that are used by all of the different components within the control cabinet, then architects know they can use that component on any new deployments or retrofits. This provides elevator designers with financial benefits. For example, they now only need to purchase one component for full interoperability, and they can also bulk buy allowing them to enjoy economies of scale. In addition, they don’t need to keep spare stock, which can simplify the stock management as well as reduce the risk that they will purchase a product and not deploy it in the future. EMI resistance for smooth ride As almost every control cabinet has a lot of electronic devices, the components must be able to withstand high EMI to ensure smooth, reliable operations. Future-proof security As the trend of digitization continues, ensuring that each component on a network is secure is going to prove more important in order to prevent against cyberattacks. As an example, compliance with the IEC 62443-4-2 industrial automation and control systems standard will help future proof the components by ensuring that the devices are going to be secure on the networks of the future. Conclusion The elevator market is truly global. With each deployment, engineers must consider different factors and overcome different challenges, but they are also presented with many opportunities to enhance efficiency. For most elevator retrofits, or new buildings with only a few floors, interoperability and features that minimize downtime are two of the most important factors. In addition, deploying components that simplify processes for those who may have limited experience working with the components are going to ensure that elevators remain operational as close to 24/7, 365 days of the year as possible. In the trend of digitization, Ethernet switches are the dispensable key components for elevator control. New smart switch technology can be monitored on HMI/SCADA systems, while keeping the configuration and operation easy and flexible.
