After Power On the module sends an emergency object with all Bytes = 0 to
signal that the initialization is ready.
Another emergency object is sent if the loaded settings are default settings.
There are two reasons for that:
• no settings are stored so far (Index 0x1010)
• The default setting are loaded (Index 0x1011)
7.3.8.1 Diagnosis messages of the outputs
The module monitors the output drivers and, in the event of an error, sends an
emergency message containing the diagnosis information of the outputs. The
diagnosis information is arrived at by a comparison of the put out status and
the internally read back status. The following are causes for a diagnosis mes-
sage to be activated:
• Missing current supply for the outputs
• Short circuit of an output
• Feed into an output
• Internal malfunction of an output level
The internal processing of the output information increases the duration of a
pending diagnosis message to at least 1s. A set bit ('1') in the diagnosis byte
means: "Diagnosis event pending at the output".
