The OneWireless network is used to connect Siemens S7 300 PLCs to the Honeywell TPS system. The PLCs are then used to manage equipment and instruments installed at each tank and pool. Since installing the OneWireless solution, the use of water is much more efficient because Codelco can accurately gauge the level of water in the thickeners. “We chose the OneWireless system from Honeywell
because it offered the most dependable solution for both our complex operation and the advanced control application, since it provides a higher capacity to support real-time gauging and instrumentation,” said Guillermo Cortés, concentrators’ automation leader, Codelco. “Our desert zone has many challenges including topography, the long distance between the thickeners and control room, and the extreme environment conditions of radiation, wind and temperatures. We are very pleased with the reliability of the Honeywell solution.” There are seven OneWireless multinodes covering the

largest copper producer, needed to optimise the water recovery process of the thickener pools at its Norte mine in Chile. The company chose Honeywell’s OneWireless Network to connect new field devices there to the existing Honeywell TPS control system.
site. One gateway is used to send the Modbus data collected from the PLC to the Honeywell TPS. With the installation of OneWireless, operators in the control room can call information from the PLCs under the Honeywell TPS control system. This information can be fed into the profit controller application to optimise process control of the facility.
After the successful implementation of the network to
support PLCs, Codelco decided to install Honeywell XYR 6000 high level analogue input transmitters to monitor the level of the clear and dark water using ultrasonic transmitters. l
