The
LHMI is an accessory for the relay which is fully operational
even without the LHMI. The relay communication card has a
dedicated port where the LHMI is connected using an RJ-45
connector and a CAT6 S/FTP cable. The LHMI can be
connected to the relay also via station communication network
if a longer distance is required between the relay and the LHMI.
Additionally, the LHMI 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 Web HMI connection.
Data transfer to a USB memory is enabled via the USB port. By
default the USB port is disabled and has to be taken into use
with a specific parameter.
