Note
PROFINET IO, behavior of the digital inputs and outputs
In the following cases, the digital inputs and outputs of the Extension Unit PROFINET are set
to "0". This means the operator controls with LEDs do not light up:
•
The CPU stops.
•
Undervoltage is detected.
•
When the PROFINET IO connection is disrupted
4.5
Power consumption of the Advanced operator controls
Under "General > Energy consumption" in the properties of the communication module, the
power consumption is shown for each Advanced operator control ("Module") and the (total)
sum.
●
A communication module supplies the connected Advanced operator controls with
maximal 24 W.
●
An RGB illuminated pushbutton consumes approx. 0.5 W.
●
A KP12 module needs approx. 2.6 W.
When the power consumption of the configured Advanced operator controls exceeds 24 W
in total, the following happens:
●
The "Sum" value becomes negative.
●
The last operator controls which contribute to exceeding the limit are marked in color.
●
An error message appears during compiling.
●
The project cannot be loaded.
