All-In-One controller with Custom Switchgear HMI architecture

Custom Switchgear HMI

Control Schemes:

#1 – All-In-One switchgear controller architecture

#2 – All-In-One controller with Custom Switchgear HMI architecture

#3 – Ethernet-backboned switchgear HMI / PLC

This architecture is similar to scheme #1, except a custom touchscreen HMI is included. Typically the all-in-one controllers include a communications port that can be interrogated by a separate HMI. LEC adds value in this process by custom programming the HMI to have a friendly, graphical presentation that make operations intuitive and simple.

  • Advantages: Easy, intuitive operation. The custom touchscreen HMI adds a built-in webserver that in some cases makes remote operation easier.
  • Disadvantages: A somewhat more expensive design than scheme #1. The design has some limitations – primarily the limitations of the all-in-one controller.
