3.6 Cyclic and acyclic data

3.6 Cyclic and acyclic data
The data communicated between SITOP UPS1600 and the PROFINET IO-Controller can be
viewed in SIMATIC STEP 7 or SIMATIC STEP 7 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 106).
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 107).

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.
Slot

Buffer mode
Ready for buffering
Charge sufficient
Description
Input voltage is present:
• 0: NOT OK
• 255: OK
Buffer mode:
The load connected to the
SITOP UPS1600 is supplied via the
energy storage device connected
to the SITOP UPS1600:
• 0: inactive
• 255: active
Ready for buffer operation as the
energy storage device of the buff-
er component has been sufficient-
ly charged.
• 0: NOT OK
• 255: OK
Charge level sufficient: When this
flag is set, the required charge
level has been achieved:
• 0: NOT OK
• 255: OK
