PLC Upgrade

AED designed and commissioned a new PLC system to support a plant upgrade. The new equipment, Allen Bradley Compact Logix hardware, required a detailed design in which AED developed P&IDs and functional descriptions for the PLC hardware. The plant’s operations were running on small outages (only a few hours at a time) which provided narrow windows of opportunity for the switchover to occur. The AED commissioning and construction management team completed the switchover and commissioning activities in two weeks. During this time, the company provided project management services for the overall project, coordinated with vendors and contractors, and managed the project schedule.
