Note
PROFINET IO, behavior of the digital output/operator control LEDs during operation
In the following cases, the digital outputs of the Extension Unit PROFINET are set to "0".
This means the operator controls with LEDs do not light up:
•
After the device is switched on
•
When the PROFINET IO connection is disrupted
•
When the Extension Unit recognizes an IOPS=Bad in the cyclical output data for the
controller (IOPS=Input/Output Object Provider Status)
Emergency stop button
Emergency stop buttons are not configured with the Extension Unit PROFINET. They are
hardwired instead using the X10 interface.
Note
Configure emergency stop button only for Extension Unit PROFIsafe
When you place an emergency stop button in a slot of the Extension Unit PROFINET, an
error message is displayed when compiling the project as part of the consistency check
informing you that the project cannot be compiled.
Place emergency stop buttons in the configuration only in a slot of an Extension Unit
PROFIsafe.
This next section describes how to configure emergency stop buttons for an Extension Unit
PROFIsafe.
