Hmi Communication Ports - ABB RELION REX640 Operation Manual

REX640 overview
identifying which relay requires operator's attention when the bay overview is not
visible on the navigation page.
When the HMI view is opened for a relay, the SHMI works exactly like a normal HMI.
All the same features are available, and the Home button switches between the
configured home pages and indicates the alarm status for the respective relay.
Navigation area on the top left corner of the HMI view is used to navigate back to
the SHMI's navigation page. The navigation area shows the bay name on the button
to identify which relay's HMI is open.

HMI communication ports

The relay communication module has a dedicated port where the LHMI is connected
using an RJ-45 connector and a CAT 6 S/FTP galvanic cable. The HMI can be
connected to the relay also via station communication network if a longer distance
is required between the relay and the HMI.
Additionally, the HMI contains one Ethernet service port with an RJ-45 connector
and one USB port. The service port can be used for the PCM600 connection or
for WHMI connection. Data transfer to a USB stick is enabled via the USB port.
By default the USB port is disabled and has to be taken into use with a specific
parameter.
