If I connect for example a net "+5V" to a component U2A which has an VCC
input as invisible pin, I see that in PCBnew the pin is connected to
the "+5V" net as soon as I set an Powerflag to +5V.
But the ERC check in eeschema states this as error :
ErrType(5): Conflict problem between pins. Severity: error
@ (5,1000 ",6,7500 "): Cmp #FLG01, Pin 1 (power_out) connected to
@ (4,4000 ",6,7500 "): Cmp #FLG06, Pin 1 (power_out) (net 3)
If I don't connect a Powerflag to the "+5V" net, in PCBnew the Power Pin
of U2A is still connect to the VCC net and not to "+5V" as set in the
schematic.
Please see schematic for example:

What I am doing wrong?
Thank you,
best Regards,
Mark

You need only connect the power to one part of a component for all parts
of that component to be powered from the same rails. However, if you
have, for example six quad nand gates (ie six components), then
connecting one part of one quad nand gate to a different set of power
rails doesn't connect up the other five quad nand gates, just the three
other gates in the same component.
