Pr S.01.024 and Pr S.01.025 display the input and output processing times respectively.
The input processing time (Pr S.01.024) shows the time taken from the value being sent
from the drive to the value being written to the master controller in milliseconds. The
output processing time (Pr S.01.025) shows the time taken from the value being sent
from the master controller to the value being successfully written to the drive in
milliseconds.
The SI-PROFIBUS module provides an input/output consistency feature which ensures
that the data in the input or output mappings is only transferred between the
SI-PROFIBUS module and the master controller when the mapped parameters are
ready. This prevents data skew between parameters in the input/output mappings.
If input consistency action (Pr S.01.026) and output consistency action (Pr S.01.028)
are set to 0 (i.e. default settings), then the input/output consistency features are
disabled so that input and output data is always transferred between the master
controller and the drive.
