How to reset the product after a power loss or when the power has been unexpectedly removed
The settings for the product are retained in memory prior to the power loss or de-energizing of the product.
The output condition is also recoverable to that prior to the power loss or de-energizing. However, this may
change depending on the operating environment. Therefore, check the safety of the whole installation before
operating the product.
If the installation is using accurate control, wait until the product has warmed up (approximately 10 to 15
minutes) before operation.

IO-Link Specifications

■IO-Link function overview

○Communication function
This product can check the commanded flow rate setting as well as the measurement value, diagnostic
information, and switch output status through the cyclic data communication via the IO-Link system.
○Product status monitoring function
This function monitors the product status via IO-Link.
•Multiple error conditions (e.g. internal hardware errors) can be monitored.
•Multiple warning conditions (flow rate measurement error, etc.) can be detected.
○Data storage function
The data storage function stores the IO-Link device parameter settings to the IO-Link master.
With the IO-Link data storage function, the IO-link device can be replaced easily without re-setting the
equipment construction or setting the parameters.
When the device parameters are set and downloaded to the device using the IO-Link setting tool, the
parameters will be uploaded to the data storage in the master by the system command after download
(backup instruction by the communication command).
When the device is replaced with the same type of IO-Link device due to failure, the parameter settings
stored in the master are downloaded automatically, and the device can be operated using the parameter
settings of the previous device.
Device parameter setting is applicable to 3 types of back-up levels of the master setting ("Inactive",
"Back-up/Restore", "Restore").
"Back-up" implies the activation of an upload and "restore" implies a download.
