Enterprise Automation has commenced design of a controls refurbishment at J.R. Simplot Company’s Helm fertilizer production facility. The refurbishment will utilize an Allen-Bradley ControlLogix PLC with Flex I/O interfacing to a redundant CitectSCADA system. The new system replaces the aging Modcell distributed processors with a centralized control strategy. Scope for the project includes field studies, panel design and supply, panel rehab, control description development, PLC programming, SCADA configuration, acceptance testing, and commissioning. The J.R. Simplot Company’s Helm fertilizer production facility is a major supplier of Ammonium Nitrate to the agricultural sector.
