Common use of Distributed Control System Clause in Contracts

Distributed Control System. A microprocessor-based Distributed Control System (DCS) shall be provided for controlling, monitoring, indication, alarm, and historical functions. CRTs located in the main control room shall serve as the primary operator interface. This system will monitor, alarm, and provide limited control of the combustion turbines. CTGs remote CRTs shall be provided in the main control room for detailed controlling, alarming, and monitoring of the combustion turbines. A MODBUS or Ethernet communication link for data acquisition shall be provided between the turbine controls and the DCS for each combustion turbine. Control functions between the DCS and turbine control systems shall be via hardwired signals. The DCS and the PLC shall be as manufactured by a reputable DCS and PLC supplier with a proven track record in the power industry (approved by Purchaser). Any normally operating auxiliary systems during normal startup and shutdown operation of the Plant shall be controlled through the DCS. The DCS shall be capable of allowing control and data to be passed between the ISO and the plant’s AGCT or RIG system. The microprocessor-based DCS shall be complete with design, engineering, materials, manufacture and assembly, optimization, documentation, testing, and field services. The DCS shall include automatic control and monitoring of the startup, shutdown and normal operation of the Plant systems through redundant Plant communication loops. The DCS shall provide automatic and manual control of all major subsystems. The Facility shall include a master clock system synchronized with satellite (GPS) complete with antenna, accessories, and equipment. This master clock system shall provide time synchronization signals for all control systems for the plant requiring time synchronization.
