About this file
This is an Input/Output (I/O) List document for the SCADA Operating System supporting the Skytop Lodge Sewage Treatment Plant Upgrade Project in Pennsylvania. The document provides detailed technical specifications for control panels and monitoring systems across multiple treatment process areas, including the Influent Screen Control Panel (10-CP-101), Equalization Tank Control Panel (10-CP-102), and Recirculation Wet Well & Secondary Clarifier Control Panel (40-CP-400). The I/O list identifies 67 distinct inputs and outputs encompassing level sensors, float switches, pump and blower controls, flow meters, and alarm systems distributed across influent screening, equalization, recirculation, clarification, post-aeration, and backup power management functions. Each line item specifies equipment tags, signal types (analog or digital), operational ranges, source and destination control panels, and implementation remarks indicating whether data connections are contiguous registers, hardwired, VFD Ethernet parameters, spare holding registers, or Modbus communications.
The document serves as the technical blueprint for systems integration and configuration, with all marked items designated for implementation by the systems integrator or through specified communication protocols. The Autodialer (40-AD-400) and Automatic Transfer Switch (40-ATS-400) inputs provide facility-wide alarm notification and generator backup power monitoring capabilities. The I/O list was prepared as of April 27, 2026, corresponding to the bid opening scheduled for September 18, 2026, with a pre-bid conference held on August 25, 2026 at the Skytop Lodge STP location in Canadensis, Pennsylvania. Bid security of 10 percent is required from contractors responding to Contract 2026-01, Project Number 005153.0436.
