A1. Introduction
The YFGW710 Field Wireless Integrated Gateway and field wireless devices are used to build an
industrial wireless network that conforms to ISA100.11a, the wireless communication standard
for industrial automation specified by the International Society of Automation (ISA).
As shown in Fig. A1-1, the YFGW710 Field Wireless Integrated Gateway plays a key role in the
wireless network and has the following functions:
• Allows field wireless devices to join the wireless network, forms and maintains communica-
tion routes, and manages the wireless network for monitoring the communication state
• Stores Publish*1 data of field wireless devices in the Modbus register for transmitting it to
CENTUM VP or other host systems
• Transmits process data to the host system via a Modbus/TCP or dedicated OPC server
• Relays on-demand communication for parameter setting and management between field
wireless devices and PRM
*1: Action to measure the process value at intervals preset in the field wireless device itself and transmit it via wireless communi-
cation
This manual explains the YFGW710 Field Wireless Integrated Gateway (hereinafter referred to
as YFGW710) and the field wireless network.
Among field wireless devices, our wireless EJX (Differential Pressure/Pressure Transmitter) and
wireless YTA (Temperature Transmitter) can communicate with the YFGW710. Devices certified
as compliant with the ISA100.11a standard can communicate with the YFGW710 and join the
wireless network.
For details of field wireless devices, refer to the user’s manual of the respective devices.
For the overall system configuration including the field wireless network and a host system, refer
to the general specifications:
