Device status indicator
The device status indicator changes its colour based on the NAMUR NE 107 recommendation.
The color of the device status indicator gives the following pieces of information:
• Whether device diagnostics are active on not.
•
If device diagnostics are active, then the device status indicator shows whether diagnostics events have
been generated or not. If several diagnostics events have been generated, then the device status indicator
shows the diagnostics event with the highest priority. Refer to
.
If the device status indicator flashes, then the device is selected in a man-machine interface such as the
Bürkert Communicator software.
