7.4 Connecting to the Field

Wireless Network

■ Preparation work prior to connecting to a

Field Wireless Network

This transmitter does not need to be connected

with a physical wire. Instead of physical wiring, it

is necessary to set the field wireless devices to

communicate with before installing the transmitter.

This procedure is called a provisioning.

This transmitter supports provisioning via infrared

communication using a provisioning device and

can be securely connected to a network. If the

provisioning information is not set, the transmitter

cannot be connected to the field wireless network.
Provisioning:

Provisioning is work to set the security and

network information to enable the transmitter

to be connected to the field wireless network.

This transmitter supports a provisioning method

using infrared communication.

For details on provisioning using a provisioning

device, and procedure for connecting the

transmitter to the Field Wireless Network, refer

to the User’s Manual, FieldMate Versatile Device

Management Wizard (IM 01R01A01-01E),

YFGW710 Field Wireless Integrated Gateway (IM

01W01F01-01EN) and YFGW410 Field Wireless

Management Station (IM 01W02D01-01EN).

Provisioning Example

■ Provisioning work
This subsection describes provisioning work using

FieldMate as the provisioning device.

Provisioning work performs provisioning for

each field wireless device using FieldMate and

an infrared adapter. If Yokogawa-recommended

infrared device is used for provisioning, distance

between the transmitter glass window and the

infrared device should be within 30cm. For details of

Yokogawa-recommended infrared device, refer to

subsection 9.2 “Calibration Instruments Selection”.

Perform the following provisioning tasks.

• Setting provisioning information

• Creating a provisioning information file

1) Setting provisioning information

Set the device tag and network ID using a

FieldMate provisioning function. The device

tag, network ID, and join key are set in the Field

Wireless Device. It is not necessary to input

a join key because FieldMate automatically

generates it.

Setting device tag

The device tag is used for the user to

recognize the Field Wireless Device.

Setting network ID

This is the network ID for the field wireless

network to which the field wireless device is

connected. Set a value from 2 to 65535.

The field wireless device is connected to the

field wireless network corresponding to the

network ID set by provisioning work.

2) Creating a provisioning information file

The following provisioned information is stored

in the provisioning information file.

• Network ID

• Device tag

• EUI64

• Join key

• Provisioner (name of the user who performed

provisioning work by FieldMate)

• Date (Time and date when provisioning was

performed by FieldMate)

This provisioning information file is required to

load from the Field Wireless Configurator to the

Field Wireless Integrated Gateway. Store the

file carefully.
