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
NUM
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | - | - |
Output NUM displays the number of CAN 2.0A telegrams not yet read from the buffer of the selected identifier. Stopping the PLC using the keypad or the online functions “STOP”, “Reset” or “Reset (cold)” does not influence the output value.
NUM_REC
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
Output NUM_REC displays the number of received CAN 2.0B telegrams, regardless of whether a corresponding buffer has been set via the PLC configuration or not. The value can be reset to 0 using the online functions “Reset” or “Reset (cold)”. Stopping the PLC via the keypad or the online function “STOP” does not influence the output. In this case, the values are kept.
NUM_REJ
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
Output NUM_REJ displays the number of CAN 2.0B telegrams rejected due to a full receive buffer. The value can be reset to 0 using the online functions “Reset” or “Reset (cold)”. Stopping the PLC via the keypad or the online function “STOP” does not influence the output. In this case, the values are kept. Whether incoming telegrams are generally discarded in case of a full receive buffer or the oldest entry stored in the buffer is always overwritten by a new telegram can be set using the controller configuration.
NUM_OWR
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
Output NUM_OWR displays the number of CAN 2.0B telegrams overwritten by a new incoming telegram due to a full receive buffer. The value can be reset to 0 using the online functions “Reset” or “Reset (cold)”. Stopping the PLC via the keypad or the online function “STOP” does not influence the output. In this case, the values are kept. Whether incoming telegrams are generally discarded in case of a full receive buffer or the oldest entry stored in the buffer is always overwritten by a new telegram can be set using the controller configuration.
