Computer Controlled Systems

Our PSC consultants possess some of the industry’s most knowledgeable staff for the validation of various computer control systems. Our expertise enables our clients to operate control systems as efficiently and simply as possible.

Distributed Control Systems (DCS)

DCS are system architectures for process control applications. It integrates the programmable logic controller (PLC) and other controllers such as process controllers, sensors, actuators, and terminals. It can also be interfaced to a workstation. DCS allows users to manage the process as a complete system with centralized control while maintaining the capability of distributed or local control of various subsystems. DCS typically consist of the following:

  • Remote control panel
  • Communications medium
  • Central control panel or facility
  • Control, interface and database software

Supervisory Control and Data Acquisition (SCADA)

SCADA refers to systems that perform both the monitoring and control of a process or facility remotely through coded communication channels. This type of Industrial Control System (ICS) is characteristically employed for large-scale processes or facilities covering multiple sites/location points.

  • Human-Machine Interface (HMI)
  • Supervisory (Computer) System
  • Remote Terminal Units (RTUs)
  • Communication infrastructure

Building Management Systems (BMS)

Building Management Systems (BMS) are typically used in buildings or facilities to create a central computer-controlled method of controlling, monitoring, and optimizing utilities such as heating, ventilating, air-conditioning, lighting, fire systems, and security systems. The entire BMS is comprised of a network of inter-operable, stand-alone, digital controllers communicating on an open protocol communication network to a host computer within the facility, and communicating via the intranet to a host computer in a remote location. The BMS is also able to communicate to third party systems such as chillers, boilers, air handling systems, energy metering systems and other energy management systems, access control systems, fire-life safety systems, and other building management related devices with open interoperable communication capabilities. We can help you implement BMS to offer you increased energy savings.

  • Honeywell
  • Johnson Controls
  • Andover

Manufacturing Execution Systems (MES)

Manufacturing Execution Systems (MES) support the primary production processes in a manufacturing or production plant. MES are IT solutions that 1) collect production input from automatic and human interface data collection devices 2) make the data available to other planning software, and 3) directly, or through interfaced software, substantially aid production line management by using real-time observations of production activity to make adjustments that improve operational efficiency.

  • Finite scheduling
  • Workflow management
  • Work order management
  • Material planning
  • Labor management
  • Maintenance management
  • Document control
  • Product material history
  • Quality and performance analysis

PSC can help you by giving your organizations visibility and control of production sites and processes throughout the enterprise.
