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
NODE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| ARRAY OF BOOL | - | 0 … 127 | - |
NODE outputs the status survey as a bit field. Each individual bit within this field represents one slave. The index number corresponds to the slave’s node address. If a bit is set to TRUE, the state selected using TYP applies to the corresponding slave.
If e.g. TYP = 1 is selected and NODE[2] = TRUE, the slave with this node address was successfully configured by the master and is currently in operation. If NODE[2] = FALSE, the configuration of the specific slave has not yet been completed or the slave is not part of the master’s configuration data.
If TYP = 3, NODE[2] = TRUE for example means that the slave with the node address 2 has received an emergency message or that the diagnosis indication of the slave has changed. In this case, a detailed diagnosis can be requested using the Function Block CANOM_NODE_DIAG CANOM_NODE_DIAG.
The at “NODE” output bit field is only valid, if DONE = TRUE and ERR = FALSE.
