Application a single realm, ensuring that different utilities are not able to see each other's private information. Installation And Customization The hosting process requires a PLC at each site to collect data that can be sent to the hosted SCADA application by the cellular modems. If a customer already has these devices in place, they are simply reused in the new system. If not, the utility is provided with a PLC that can communicate with its existing equipment. If the customer has a piece of equipment that cannot com- municate with DNP3, Modbus, or any other communication protocol that the SCADA software recognizes, the engineer can tie in a PLC, which has a built-in DNP3 communication driver and directly wire in the equipment information into inputs and/or outputs of this new PLC. The PLC can then transmit equipment information to the hosted SCADA system through any cellular-based network. In addition to standard pre-built template pages, Kennedy also provides engineer- ing time to create a selection of customized graphic screens unique to each of their customers. Since each customer remote site is configured as an area within the Internet hosted SCADA system, all that custom- ers require to view the realm of their areas is a Windows computer with Internet connection running Internet Explorer. Customers can also access the system from their smart phones or tablets. A Secure Cloud Kennedy runs their hosted appli- cation at a local server farm, which guarantees 24/7 power and Internet connection. For security, the integrator uses its own SSL certificate, which encrypts user- name and password information in addition to the VTScada advanced security features. As a further safe- guard, Kennedy is working on an approach where the hosted solution is configured as the main system but another VTScada appli- cation is installed at the customer site as an automatic backup. Room to Grow Beginning with a hosted solu- tion makes it easier to switch to a traditional SCADA application in the future as their resources grow. Since KISM is built on Trihedral's fully featured SCADA software, customers can choose to end their service contract with Kennedy and roll out to a full installation at their site if their needs change. Just as in the backup scenario mentioned above, Kennedy can move the customer's application to an on-site SCADA server. Reasons to change could include greater ability to customize the application in house. Hosted solutions allow utilities to quickly implement world-class SCADA systems while eliminating the need for extensive infrastructure and IT staff. Customers have peace of mind knowing that their system is always available and sup- ported by a team of dedicated experts. Thelma Akwei joined Trihedral in 2009 as a marketing coordinator.
