B1.3.1.2 Task of Replacing YFGW710
Replace YFGW710 following the steps below.
1. Task of setting YFGW710 (in section B1.2.3.1 of this document)
2. Installing YFGW710 at the plant site
3. Task of downloading to YFGW710 (in section B1.2.4.2 of this document)
4. Task of checking the field wireless network operation conditions (in section B1.2.5 of this
document)
5. Checking process data communication (in section B1.2.7 of this document)
l Notes
▪ When downloading to YFGW710, the task of “Registering Provisioning Information with the
Project Database” in section B1.2.4.1 of this document does not need to be performed.
▪ Ensure that the power supply of the existing YFGW710 to be replaced is turned off before
performing the replacement task. If the existing YFGW710 to be replaced is running, radio
signals of the new YFGW710 and the existing YFGW710 to be replaced interfere with each
other and the replacement task cannot be performed correctly.
▪ When downloading to the new YFGW710 is completed, YFGW710 restarts. It may take
about 30 minutes until all the field wireless devices have joined the field wireless network.
▪ Since a field wireless device that has joined the field wireless network automatically starts
process data communication, the task of “Downloading the Process Data Communication
Definitions” in section B1.2.7 of this document does not need to be performed.
▪ To check whether or not process data communication has started correctly, it is recommend-
ed to perform the checking task described in “■ Checking Process Data Communication” of
“Task of downloading the Process Data Communication Definitions” in section B1.2.7 of this
document. During the time until process data communication has started correctly, IOP is
displayed in HMI of Yokogawa’s control system.
