2.4.2 Configuration of the SITOP UPS module
Buffering parameterization
The UPS module can be used to select whether buffering should be completed after a
predetermined period of time or not until the accumulator’s lowest discharge threshold (=
maximum buffer time) has been reached. Both buffering parameterizations result from this.
"Maximum buffer time" mode (PCU basic software XP 08.00.00 or higher)
This mode enables the system to be shut down in a time-optimized manner. The UPS
module is synchronized with the shutdown of the operating system. Buffering is maintained
until the operating system has been shut down. The operating system must shut down within
a maximum of five minutes (including all applications). Otherwise, the UPS module buffers
for the maximum buffer time (dependent on the accumulator state).
