Device data
The device parameters contain all application data (e.g. setpoints and actual values, limit values, ...)
for operating the drive system. Changes to the device data are exchanged acyclically between the
IO-Link master and EMCS-ST.
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" instruction manual è www.festo.com/sp) are
made automatically and permanently 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.
