4.1.4.2 UPS

IPCs can be equipped with a capacitor package. The capacitor package serves to buffer the

current supply of the IPC. This compensates current fluctuations and in case of a complete

power failure, these capacitors ensure the current supply. To bridge a longer power failure,

rechargeable battery packs are available.

Within this protected time, the control can save especially marked variable contents (reta-

in variables). The retain variables will continue to be available in case of a restart of the sys-

tem. Depending on the series, the capacitors are already integrated or can be connected

externally.
