The example shown above looks in the Device Configurator regarding internal
power supply as follows:
The module carriers have 2 or 4 slots.
The last, empty line with only a +, indicates
that no further module carrier follows, i.e.,
the end of the system structure.
Total current of the I/O modules in the CPU and
all following in the PCD3.C100 or PCD3.C110
module carriers.
As soon as a PCD3.C200 module carrier with
power supply is used, the calculation starts
again until the next PCD3.C200 etc.
Once the current limit is exceeded, the
configurator will reports this.
The Device Configurator shows the power con
-
sumption according to the modules used.
The CPU supplies slot 0 ... 11 (with two
PCD3.C100), i.e. a total of 12 I/O modules
with internal current of 412 mA [5V].
188 mA are reserve.
The last entry in the module carrier stands
for the following, in this case, a power-
supplying PCD3.C200 module carrier.
The configurator displays the power
consumption of the next I/O modules up to
another PCD3.C200.
