Figure A2-1 Minimum configuration
Figure A2-1 shows the minimum configuration with a single YFGW510, and Figure A2-2 shows
the YFGW510-redundant configuration employing the Duocast technology (each wireless field
device communicates with two YFGW510s).
The wireless backbone network consists of the YFGW410 field wireless management station, the
YFGW510 field wireless access point and the YFGW610 field wireless media converter. Any of
the following connection methods can be selected.
1. Metal network cable (100BASE-TX)
2. Optical fiber network cable (100BASE-FX)
YFGW610 must be installed between YFGW510 and YFGW410 for optical fiber network
connection to convert it to metal network connection.
3. Wireless LAN connection
Recommended access points for wireless LAN must be installed between YFGW510 and
YFGW410 for wireless LAN connection to convert it to metal network connection.
For recommended wireless LAN access points, see the User's Manual of YFGW410 field
wireless management station (IM 01W02D01-01EN).
