USAT Corp Keeps Durham Flowing With SCADA Water System
Once engaged, USAT Corp. was able to determine that a commonly used one-modem-to-one-location network architecture would not work. The Allen-Bradley programmable logic controllers (PLCs) and controls panels pre-existing in Durham’s infrastructure were incapable of Port Address Translation (PAT) and without this functionality, the network design would need to change.
Without PAT, each piece of equipment on each tower’s LAN would require its own individual wireless gateway, data line, static IP address, and other equipment in order to facilitate cross-network communication. This development was a major hurdle, because if the costs for the equipment and Verizon Wireless 4G data plans required for the system upgrade increased, then Durham’s project budget would have to increase, which was not a welcome change.
However, faced with this technical challenge, USAT was able innovate a solution to successfully work around the problem and to avoid an increase to the project budget.
