① System power supply:
Power supply (PS) module + integrated power supply module of the interface module (PS
int
)
for supplying the I/O modules via the backplane bus
② Backplane bus
③ Load power supply:
Power module (PM) or SITOP for supplying the modules (PS, interface module, I/O
modules) and, where applicable, the sensors and actuators
