4.21 Fieldbus CPUs
Fieldbus CPUs are a variation of Compact CPUs. Their modular structure makes it easy to meet the unique re-
quirements of each application.

The battery-free CPU
To meet the high demands of the market, the Fieldbus CPU was designed to run without a battery. This makes it
completely maintenance-free. The following features make operation without a buffer battery possible.
The real-time clock is buffered for approx. 1000 hours by a gold foil capacitor.
This FRAM stores its contents ferroelectrically. Unlike normal SRAM, this does not require a battery.
Compact design
Despite the sleek profile of only 62,5 mm, the CPU supply, the X2X Link bus supply, and the I/O module supply
are integrated in the CPU. No additional power modules are necessary.
