Colour coding
Note
The colour of a device corresponds to the colour of the virtual LEDs in the diagnostic view of
the ASIMON configuration software. A device which is not assigned to any output circuit is al-
ways shown in green.

Note
During proper protective operation, there are also devices which are not in the green state.
When searching for the cause of a shutdown, the device with the lowest device index is the
most important. Others may just be subsequent effects (example: when the emergency shut-
down button is pressed, the start device and timer are also in the OFF state).
By appropriately programming the functional device in the PLC, the user can be guided to the
primary cause of the error. Detailed knowledge of the configuration and the function of the
AS-Interface safety monitor are necessary for the interpretation of additional information.
Because the device numbers can be shifted if the configuration is changed, we recommend
using the diagnosis index assignment.
