Cyclic and acyclic data
The data communicated between the SITOP UPS1600 and the PROFINET IO-Controller
can be viewed in STEP 7 or classic in the TIA Portal. Here, a distinction is made between
cyclic data (input/output data) and acyclic data (reading/writing data sets).
Input/output data
SITOP UPS1600 sends, in cyclic intervals (1 ms - 512 ms for IRT or 1 ms - 2048 ms for RT),
data about the actual operating states to the PROFINET IO-Controller. You will find more
information on this at Input and output data (Page 122).
Reading and writing data sets
Reading and writing data sets are sent acyclically from the SITOP UPS1600 to the
PROFINET IO-Controller or from the PROFINET IO-Controller to the SITOP UPS1600.
Additional information can be found at Reading and writing data sets (Page 123).

Input and output data
An overview of the input and output data, which is cyclically sent from the SITOP UPS1600
to the PROFINET IO controller is provided in the following tables.

Description
Input voltage is present:
0: NOT OK
•
255: OK
•
Buffer mode: The load connected
to the SITOP UPS1600 is sup-
plied via the energy storage de-
vice connected to the
SITOP UPS1600:
0: inactive
•
255: active
•
Ready for buffer operation as the
energy storage device of the
buffer component has been suffi-
ciently charged.
0: NOT OK
•
255: OK
•
Charge sufficient: The required
charge has been reached when
the flag is set:
0: NOT OK
•
255: OK
