Description

Specifications include, but are not limited to: The project consists of a base scope of work with alternate scope items. The base scope of work generally consists of replacing existing Programmable Logic Controllers (PLCs) at various control panels within Wastewater Treatment Plant (WWTP) No. 2, as well as the SCADA server. The existing PLCs are Allen-Bradley SLC series, and will be replaced by Allen-Bradley CompactLogix series. The existing SLC series PLC processors communicate using the DH+ protocol over fiber optic to an existing ControlLogix PLC which communicates on both the DH+ and Ethernet networks to allow data transmission to the SCADA system as well as other PLCs. The new CompactLogix PLCs (replacing existing SLC series PLCs) will utilize the existing fiber optic cable to integrate into the existing Etherent/IP network.
