Ravensdown wanted support for automation requirements in their project, to upgrade existing circuit capacity from 49tph to 80tph superphosphate and to modify environmental scrubbers to meet resource consent requirements.
CTEK implemented a project management plan with the development of ControlLogix PLC and InTouch Archestra HMI standard. Some individual SLC racks and I/O’s were retained and converted to run as Remote I/O’s from a new ControlLogix PLC that controls close to 800 I/O’s. CTEK also upgraded the control system of their 5MW generator in the Acid plant, and existing HMI to Wonderware Archestra platform. The Wonderware Archestra system was designed in a virtualized environment, thus allowing operators and technicians the ability to alter plant recipes, enter lab data, and retrieve reports and historian data to ensure the plant is running at optimum levels.
