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
ACT_LEN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | - | - |
ACT_LEN outputs the length of the received object data (in bytes), after the procedure has been completed successfully. Since Function Block execution requires bus access, the data are available in the next cycle after activating the Function Block at the earliest. The output value is only valid, if DONE = TRUE and ERR = FALSE.
PNIO_STATUS
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
Output PNIO_STATUS contains the PNIO ErrorCode and ErrorDecode.
PNIO_ADD_VAL1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | 1 | - | - |
Output PNIO_ADD_VAL1 contains the PNIO ErrorCode1.
PNIO_ADD_VAL2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | 2 | - | - |
PNIO_ADD_VAL2 contains the PNIO ErrorCode2.
