coupler-led
Ethernet Port
INInput port, used to connect to a Modbus TCP master station on the same subnet or to the OUT port of another Modbus TCP slave station.
OUTOutput port, used to connect to the IN port of other Modbus TCP slave stations on the same subnet.
System Indicator
PWR1 x green power indicators, used to view the power status of coupler.
SYS1 x green system tip indicator, used to check the operational status of coupler.
RUN1 x green running indicator, used to check the running status of coupler.
ERR1 x red fault indicator, used to see if the coupler is malfunctioning.
System Power Indicator
Link1 x green link indicator, used to see if the connection of common terminal is normal.
Input Voltage1 x green input voltage indicator, used to see if the input voltage is normal.
