Point-to-point operating modes

Automatic saving of device data
If automatic storage is activated (0x0109.0 = true, default), parameter changes
in the device data (= data storage parameters 

è

 "Integrated drive EMCS"

  www.festo.com/sp) are made automatically and perma-

nently saved in the flash memory. Exceeding the maximum permissible 100,000
write cycles results in irreparable damage to the flash memory and the device,
e.g. when using the device for positioning tasks via IO-Link.
If automatic saving is deactivated (0x0109.0 = false), parameter changes are
only temporarily stored in the RAM. The RAM permits an unlimited number of
parameter changes, e.g. for positioning tasks via IO-Link.
