<p>The operator interface device for an HMI system provides for generic, simple communication between Human-Machine Interface (HMI) software and an operator workstation. The device has at least one signaling device (54), at least one serial communication port (42), and an Ethernet port mounted on a housing (32, 46). Disposed within the housing is electronic circuitry that includes a micro controller (36) having embedded Ethernet capability. The micro controller is configured to pass serial data from a bar code reader, RFID receiver, or the like from the serial communication port (42) via Ethernet by TCP/IP to the HMI software (38) on a remote server, and to control driver (s) (40) for the at least one signaling device (54), which may be a beacon, a light, a horn or other audio device, or a push button switch (52). The device may also include a power supply (56) and mini connector port (30) for passing signals between a machine controller, such as a torque controller, and the HMI software.</p> |
