USB connector
The USB connector is a B-type connector for connection with a local personal computer.
4.1.2 Communication Ports
The following three interfaces are mounted as communication ports:
•
USB port
•
RS485 port
•
Optional Communication Unit port
USB port
This connector is a standard B-type connector for USB transmission and is mounted on the front
panel. By connecting a personal computer to this connector, setting operation and display functions
can be performed.
RS485 port
The RS485 port is used for MODBUS communication or the IEC60870-5-103 communication to
connect between relays and to construct a network communication system.
The RS485 port is provided on the rear of the relay as shown in Figure 4.1.1.
