Figure A2-1 Minimum system configuration with redundant field wireless network
This is redundant field wireless network configuration. Two YFGW510 are installed in the field
wireless network, and the field wireless devices communicate with the both YFGW510 (Duo-
cast). The communication path from the field wireless devices to the YFGW410 is made redun-
dant.
This system redundancy can prevent various types of interference in the field wireless network
environment and can maintain the high quality connection.
Up to 100 field wireless devices can be connected to a single field wireless subnet.
