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
MST_STATE
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| PNIO_MST_STATE_TYPE | - | - | - |
The MST_STATE output reflects the major state of the PROFINET Communication Module. This value is valid with DONE=TRUE and ERR=FALSE.
The MST_STATE is displayed in plain text with aid of the enumeration PNIO_MST_STATE_TYPE.
| PNIO_MST_STATE_UNKOWN | Unknown state |
| PNIO_MST_STATE_NOT_CONFIGURED | Pre-configuration |
| PNIO_MST_STATE_STOP | Configured but not running |
| PNIO_MST_STATE_IDLE | Idle |
| PNIO_MST_STATE_OPERATE | All up, normal operational state |
COMM_ERNO
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| PNIO_COMM_ERNO_TYPE | - | - | - |
The COMM_ERNO output value represents the current PROFINET bus condition. A transition of this output with DONE=TRUE to a non-zero-value signals a communication error caused by one of the reasons listed in the table below.
The COMM_ERNO is displayed in plain text with aid of the enumeration PNIO_COMM_ERNO_TYPE.
| PNIO_COMM_ERNO_NONE | No error |
| PNIO_CONIFGURATION_FAULT | Configuration fault |
| PNIO_PARAMETER_ERROR | Parameter error |
| PNIO_INV_NETWORK_ERROR | Invalid network address |
| PNIO_NETWORK_FAULT | Network fault |
| PNIO_CONNECTION_CLOSED | Connection closed |
| PNIO_CONNECTION_TIMEOUT | Connection timeout |
| PNIO_LONELY_NETWORK | Lonely network |
| PNIO_DUBLICATE_NODE | Duplicate node |
| PNIO_CABLE_DISCONNECTED | Cable disconnected |
| PNIO_COMM_ERNO_UNKNOWN | Unknown communication error |
NUM_ERRS
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
The total number of errors detected by the Communication Module since last power up or reset.
