Figure 31: Correct Power Supply Connection of Sensors via a QDIO
The attached sensors must be supplied with power from a permanently
connected (unswitched) power supply that cannot be individually
switched off, without switching off the module's power supply.
Power must not, as shown in figure-32 on page 45, be supplied from
switched power circuits!
The sensors within an I/O group must always be supplied with power
from the same power supply that supplies the relevant I/O group.
They must not, as shown in figure-32 on page 45, be supplied from a
separate power supply (due to the danger of reverse energization)!
Outputs may be supplied with power from a switched power supply, for
example with intermediate devices (emergency stop, manual operation,
etc.).
