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
RDY_PULSE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
The output RDY_PULSE is set to TRUE when all pulses have been sent.
ACT_PULSE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | - | % |
The output ACT_PULSE return the percentage of pulses sent, from 0 to 100 %.
100 % is obtained only when the totality of pulses has been sent.
On the fast outputs O0 or O1, the brightness of the yellow LED depends on the number of pulse emitted (from 0 to 100 %), When the value 100 % is obtained, the yellow LED status is off.
Output ACT_PULSE corresponds to input byte in “state byte Sx %pulse”.
