Internal and External Power Supply
Note:
Hardware revision 3 of the slot PLC NPLC-C100 can be supplied
via the PCI bus only with 5 V. Hardware revision 4 of the slot PLC NPLC-
C100 can be supplied via the PCI bus with 3.3 V respectively 5 V.
The slot PLC can be supplied by 5 V or 3.3 V (via PCI) or by an additional
external supply voltage of 24 VDC. The permitted voltage range for external
powering is 18 … 30 V. If the external supply voltage reaches a level below
13 V, then the supply of the slot PLC from the external supply voltage is
switched off.

Reset Behaviour
The slot PLC has no connection via the PCI bus to the PC reset signal.
This means that a reset of the PC for example when using the front panel
reset button of the computer does not influence the slot PLC behavior.
The PowerOn reset will be served from both power sources (internal und
external).
