A2. System Configuration
A2.1 Minimum System Configuration
Figure A2-1 shows a minimum configuration with a single YFGW410, which has PROFI-
NET interface. This figure corresponds to Figure A1-1 of the User's Manual of YFGW410 (IM
01W02D01-01EN). In PROFINET system, host system consists of PROFINET IO Controller and
PROFINET Engineering Tool and Host application.

A2.2 YFGW410 in Redundant Configuration with
Single PROFINET IO Controller
Figure A2-2 shows a typical configuration with a redundant YFGW410 which has PROFI-
NET interface. This figure corresponds to Figure A3-1 of the User's Manual of YFGW410 (IM
01W02D01-01EN). Note that host system is not a redundant configuration but a single configura-
tion.
In this example, the both of YFGW410 and YFGW510 are made redundant system. By using
Duocast, the paths between the field wireless device and YFGW510 are made redundant.
Two YFGW410 virtually operate as a single PROFINET IO Device, and the backbone devices
and host system access to this virtual device.
In case one of YFGW410 is out of service by failure, another YFGW410 continues operation.
One failure does not affect a field wireless system.
