Gannett Fleming's staff of instrumentation and controls personnel is experienced in planning, designing, and implementing a broad range of process controllers, operator interfaces, networks, and sensing systems. The real benefits to a client's project lie in the strength of the company's ability to tie together hardware and software from different manufacturers. This allows the design and installation of an economically efficient system and the capacity to integrate new systems into systems already in place. Gannett Fleming can facilitate instrument selection and specification, loop diagram development, instrument documentation, PLC specification and configuration, distributed control systems, operator interface systems (OIT, HMI, and MMI), interlock specification and design, database integration for archiving and trending, manufacturing execution systems, and back office integration. Gannett Fleming can further assist with specification and design of industrial networking including Ethernet, DeviceNnet, Profibus, ASI Foundation fieldbus, and Modbus/RS-485. This is all backed by project experience with functional specifications for batch and continuous control, cell control, machine control, and SCADA systems.
