16.1.5. ETHERNET (ETH) INTERFACE
u REG
is equipped with an insulated Ethernet 10/100BASE-T interface with a standard 8P8C
(i.e. RJ-45) port, which has two LEDs to indicate link and activity of the interface. Additionally,
port activity is signaled by icon on GH / GV graphic panels.

Fig. 16.1.5.1. Wiring diagram of Ethernet port.
TCP/IP model divides network communication into some layers operating with one another
(i.e. ISO OSI model). Each layer requires a specific protocol.
Fig. 16.1.5.2. TCP/IP layers
IP stack application layer is the highest level for services such as WWW server, FTP, SMTP. Also,
it includes a set of transmission protocols used by external programs to communicate with
u REG
.
The ETH interface in
u REG
has the following protocols implemented:

uCZIPstd – TCP or UDP transport layer,

DNP-3 – TCP or UDP transport layer,

IEC-60870-5-104,

IEEE-1588 - PTP time synchronization: precision = 1 µs,

Modbus TCP (slave/master), other.
Also, both ETH and
u REG
are adapted to handle a later IEC-61850 protocol ( real time Ethernet ).
