n Field network
Connect the 100BASE-TX compliance cable, terminated with an RJ-45 connector, to the field
network interface on the front panel of the YFGW410.
Generally, connect the host system which transmits data using the ISA100.11a protocol to the F1
port of YFGW410. Connect the host system which transmits data using the Modbus/TCP proto-
col to the F2 or F3 port.
n RS-485
YFGW410 supports to communicate with the host system, which supports Modbus/RTU commu-
nication, via the RS-485 connector on top of the main body. 4-wire and 2-wire types are provided
for connection with the host system. Selecting connection type is set by RS-485 configuration
switches. YFGW410 supports only 1 to 1 connection.
RS-485 connector is a 6-pin connector with a spring terminal (Phoenix Contact FKC 2.5/6-STF).
For details of wiring, see C4.2 Power Supply Cable Connection. Regarding RS-485 communi-
