Output Description¶
DONE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | TRUE / FALSE | - |
Output DONE indicates the state of execution.
It has the value TRUE when the execution is finished and the outputs are valid. When DONE becomes FALSE other outputs are not valid any more.
ERR
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | TRUE / FALSE | - |
Output ERR indicates whether an error occurred during Function Block execution.
It is only valid when DONE is TRUE. The kind of occurred error is specified by the error identifier at output ERNO.
ERNO
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | 0 … 65535 | - |
At output ERNO the identifier of an occurred error is provided. It is only valid when DONE and ERR is TRUE (see, error messages): Error Messages of the Function Block Libraries
MAP
| Data_Type | Default_Value | Range | Unit |

As long as EN = TRUE and at least 2 nodes are active (a network consists of min 2 nodes), output array [1..255] of BYTE shows the status information of the network map.
