Up to 20 field wireless subnets can be connected to the YFGW410.
Any of the three types of field wireless backbone can be selected for between YFGW410 and
YFGW510.
• The metal network composed of the YFGW510 (100BASE-TX model), shown in Figure
A1-1
• The optical fiber network shown in Figure A1-2, composed of the YFGW610 connected to
the YFGW410, uses the YFGW510 (100BASE-FX model) for signal transmission via optical
fiber cables.
• The wireless LAN network shown in Figure A1-3, composed of other manufactures’ wireless
LAN access point (connected to the YFGW410) for wireless LAN communication with the
YFGW510 (wireless LAN client model).
The Field Wireless Management Console, which is the program built in to the YFGW410, is used
for configuration and management of a field wireless network. This program can be started and
operated by the PC connected via the field network interface or via the maintenance interface of
the YFGW410.
Certain parameters need to be set on the following devices to configure and start the wireless
network. For the relevant procedure, see the Provisioning and Configuration section.
• YFGW410 The device parameters, wireless network configuration, commu-
nication with host system, and others
• YFGW510 The device parameters
Wireless LAN parameters if the wireless LAN client model is
selected
• Field wireless devices Provisioning and sensor parameters, and others
Once the field wireless network has started, the field wireless device parameters can be set and
those devices can be managed from the Plant Resource Manager (PRM) connected to the host
network. If the security policy for the host system is acceptable, the FieldMate can be used for
parameter setup and maintenance. The FieldMate is connected to the YFGW410 via the mainte-
nance interface.
IMPORTANT
When CENTUM VP is running, set and adjust the parameters of the field wireless device from
PRM.
When CENTUM VP is not running, or when a non-Yokogawa host system is connected, the pa-
rameters can be set and adjusted using FieldMate.
