EtherNet/IP communications provides faster better logic control

The Eurotherm Mini8 controller with EtherNet/IP communications, is an ideal partner to a PLC in multi-loop PID applications such as plastics extrusion and multi-zone furnaces. Leveraging the Mini8 controller’s built-in loop control, the PLC can concentrate on providing faster, more effective logic control without the burden of running complex control algorithms.

Part of Invensys's open-communication InFusion Enterprise Control System, the Mini8 controller supports serial, fieldbus and Ethernet protocols, including EtherNET/IP, making it easy to interface to intelligent masters such as a programmable logic controllers. A cost-effective alternative to designing and implementing accurate control loops in a PLC, the Mini8 controller not only provides better performance and easy configuration, it offers the same deterministic response and auto-tune feature as other Eurotherm panel-mount controllers from Invensys, and it can be easily integrated into the wider plant network, including other third-party systems.

Key capabilities:
• Easy integrates through use of EtherNet/IP, a widely used standard communication link between PLC’s and other products from a variety of vendors.
• Reduces engineering costs through using a dedicated PID device that enables quick and easy set-up of multi-loop and complex control strategies using pre-defined function blocks.
• Improves control performance by removing the burden of running complex control algorithms within a PLC.
• Input accuracy is +/-0.1% or better, this is significantly better than analog control in small or medium PLC’s.
• Suitable for use in regulated industry applications, including aerospace metal heat treatment.
• Calibrates through pre-defined routines.
• Impressive minimal drift characteristics aid in the ease of use of the device in operation.
