While dedicated human machine interfaces (HMIs), sometimes called operator interface terminals (OITs), have been available for many years, they have tended to use infrared or resistive touchscreens. These screens provide functionality but lack the sophistication, durability, and compact form factors of newer technologies. Today’s users are familiar with advanced HMI capabilities and experiences available throughout the consumer world on everyday devices, and they expect the same capabilities for industrial versions.
This technical article explains why designers should specify HMIs with these features, and it shows how the technologically advanced IDEC HG2J touchscreen operator interface with PCAP technology provides a premium industrial visualization solution.
