SILB with one RS485 port for ModBus and one RJ45 port for IEC61850 or
DNP3.0
The device features 1 exterior RS485 connections through three terminals (+, - y GND) located
on the back of the unit. The protocol used is Modbus RTU
These ports can be used for the continuous monitoring of the device from a remote PC or SCADA
system. Up to 32 units can be connected to one bus, each with its own modbus address. Speed
and direction are configurable.
In order to minimize communications errors due to noise, a shielded twisted conductor cable is
the recommended physical medium. In order to make the connection, connect all + terminals on
one side and all
– terminals on the other side.
If a 3 strand cable is used for communication, the ground terminals (GND) should be connected
to the earth cable.
If a 2 strand cable is used for communication, the ground terminals (GND) should be connected
to the cable shielding. The shielding should be connected to GND at only one point, so as to
avoid circular currents.
Resistance loads must be used at both ends if a very long cable is used. The best solution for
avoiding signal reflection is the addition of resistance loads at both ends of the cable. The value
of these resistance loads should be the same as the impedance of the cable.
RS485 are insulated from the auxiliary voltage, but there is no insulation between the two ends
of rs485 terminals. In highly aggressive environments fiber optics can be used, with the
corresponding converters.

Besides, there is another rear communication RJ45 port using IEC61850 or DNP3.0.
