Outcomes, Insights, and Best Practices from IIC Testbeds: Intelligent Urban Water Supply Testbed     paying for the connectivity in the business model. Enhance the visibility to the operational states of the pump, allowing the drilling down to the details of any pumps that have been connected in a digital twin model Provide product lifecycle estimates Provide pump room video surveillance and access control Optimize maintenance and repair workflow by adding a capability to a maintenance mobile app to view real time data from the pump even before arriving the pump rooms. As the connectivity and data interoperability issues are being solved, a third challenge lies in data analytics. To effectively analyze the data, it requires large amount of quality data to build models. It also needs a close collaboration between the OT and IT sides. Even when quality data have been accumulated, it is necessary not only to identify patterns in the data but also understand what those patterns mean – the latter can only come from the OT side as well. More specifically, one needs to apply OT domain knowledge to the equipment data by applying ‘labels’ to the patterns identified in them and use that to build machine learning models. This in a sense requires a close-loop of the data lifecycle and closely integrated systems where equipment maintenance and repair records can be correlated with the machine operational data. L ESSONS L EARNED One challenge the testbed has faced is interoperability - how to connect to the heterogeneous pumps made by various vendors, not just those by WPG, that have been deployed over decades. Even for the same model of pumps equipped with the same model of PLC, the data stored in the PLC could vary. The ability to adapt to various data formats is important. Sometime it may be necessary to swap out the old controllers from those pumps to enable the connection to them. Combined with other capability upgrades, this can generate revenues by adapting or transforming old equipment to new technologies. Another interesting point to bring up is that through the customer engagement in the implementation of the testbed, the team has also learned the features the customers would be interested in, not just those planned out by the testbed. For example, providing visibility to the remote assets offers substantial initial value. The ability to adapt to the customer’s need is clearly important. The testbed is able to do that by reprioritizing the feature deliveries in order to deliver the best value to the customers. There is also the issue of establishing communication from the IoT gateways that are connected to the pumps to the system in the cloud. Pumps are usually deployed in basements where the wireless signal is weak if not completely unavailable. Therefore, arrangements must be made with property management companies to enable wired connectivity. There is also the question of IIC Journal of Innovation All in all, connectivity to equipment and collecting data are what we usually first focus on in an IIoT project. However, we need to have a longer term vision of how to - 33 -
