Mini8® Multi-loop PID Controller and EtherNet/IPThe Mini8® controller is an ideal partner to a PLC in multi-loop PID applications such as multi-zone furnaces. By devolving loop control to the Mini8 controller, the PLC can concentrate on providing fast and effective logic control without the burden of running complex control algorithms. The Mini8 controller is a cost-effective alternative to designing and implementing accurate control loops in a PLC. Providing not only better control performance and easy configuration, the Mini8 controller offers the same deterministic response and auto-tune feature as Eurotherm panel mount controllers. The Eurotherm open approach to communication, supporting serial, fieldbus and Ethernet protocols (now including EtherNET/IP), makes it easy to interface to intelligent masters such as a PLC. The Mini8 is the latest Eurotherm device to include the EtherNET/IP protocol.
