IO-Link
○Communication function
This product can check the position measurement value, diagnostic information and switch output status
using cyclic data communication via the IO-Link system.
○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 parameters.
When the device parameters are set and downloaded to the device using the IO-Link setting tool, the
parameters in the downloaded device will be activated. After that, these parameters are uploaded to the
data storage in the master by stem command (back-up communication command). When the device is
replaced with the same type of IO-Link device, the parameter settings stored in the master are downloaded
automatically, the device can be operated with the parameter settings of the previous device.
3 types of back up level of the data storage can be set for each master port using IO-Link setting tool
("Disabled", "back-up/restore", "restore").
"Back-up" implies the activation of upload and "restore" implies download.
