The HMI has a LCD screen, LEDs (#1–#14), operation keys, function keys (F1–F5), and a USB
port. LCD screen can display information; e.g. IED operation menu, status, setting data,
monitoring, fault records and others. We shall see the menus on the display in Chapter
interface
later (→p. 977). USB "B-type" port is provided for the connection to the PC. Thus, the
user can connect the engineering tools (GR-TIEMS®) or the PLC editor (MULTIPLOG®) with
the IED using the USB port.
