The North Cary Water Reclamation Facility, located at 1900 Old Reedy Creek Road, was constructed and began operations in 1983. With the addition of a BNR system in 1997, the facility acquired its first major SCADA system. The SCADA system consisted of an Intellution software package and a fiber optic network. In combination with PLC 5's, SLC's
and Phoenix digital cards, a simple SCADA network was formed.
In 2005, a third BNR train was added. With this addition, the Intellution software package was upgraded to I-FIX. This was soon followed by the replacement of the phoenix digital
fiber cards, PLC 5's and SLC's with Ethernet compatible PLC 5's and SLC processors, N-tron switches and replacement fiber. Eventually, the non-managed N-tron switches were replaced with managed switches that provided a self-healing fiber backbone.
The Town will soon be seeking the services of a systems integrator (SI). The selected SI will upgrade the plant SCADA network to either a Wonderware System Platform or other platform such as Ignition. The existing SCADA software is at least eight generations out
of date. The Windows 7 PC's are simulating an XP environment to support the antiquated system. The Town has standardized hardware for both the application as well as the network switching. The existing multi-mode fiber is functional but needs to be fully terminated and mapped.
The SI will upgrade the plant network, system hardware and incorporate the plant SCADA system into the Town network. They will also be responsible for upgrading the plant fiber network and verifying its integrity.
