Fig.63: Data storage mode – general principle, Para. IOLD = parameters of the IO-Link device
A change of parameters in the device is indicated by the status of the DS_UPLOAD_FLAG bit:
n 0 = no changes in the device's parameter set
n 1 = changes in the device's parameter set (e. g. via DTM, at the device, etc.)
10.5.1 Parameter ”data storage mode” = read in
n The data set in the device is always the reference data set.
n The synchronization of the parameter sets is unidirectional towards to the master.
n The status of the DS_UPLOAD_FLAG is ignored.
