9.6 Protecting against longer power failures
Sudden and longer failures of the line supply voltage can result in undefined states and
significant danger as a result of the associated failure of the plant or system control.
The SITOP power supply product portfolio includes various DC-UPS solutions to prevent the
failure of the 24 V power supply voltage.
Power supply failures up into the minutes range can be buffered using the maintenance-free
SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow
the saving of process data and controlled shutdown of PCs (Page 100)).
Figure 9-7
Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply
integrated into PC-based automation solutions. This supports further processing of the status
signals and safely running down the PC.

Using DC UPS SITOP UPS1600 and SITOP UPS1100 battery modules, buffer times in the
range of hours can be implemented. Intelligent battery management using Energy Storage
Link automatically detects the UPS1100 energy storage device, and ensures optimum
temperature-controlled charging and continuous monitoring. The UPS1600 can be flexibly
integrated into the widest range of automation applications with its digital inputs/outputs as
well as optional USB interface or Ethernet/PROFINET port.
