Input Description¶
EN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | FALSE | TRUE/FALSE | - |
The input EN has to be driven in edge triggered mode.
The execution of the Function Block is started with a positive edge on the input EN.
In the first call it evaluates its inputs and creates a local copy of them. Afterwards it starts its internal algorithm. It may take several PLC task cycles until it is executed.
Once the execution is completed DONE and its other outputs are set. To start the Function Block again a new positive edge on the input EN has to be applied.
SLOT
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | 0 | 0 … 4 (6) | - |
At input SLOT, the Communication Module slot is specified which should be used by the Function Block.
The internal Communication Module always has the index 0. All external Communication Modules are serially numbered from right to left, starting with 1.
ID
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | - | - |
Input ID is used to specify the identifier of the CAN 2.0B telegrams to be read from the buffer. If no buffer has been specified for the selected identifier using the controller configuration, this is indicated accordingly at the Function Block outputs.
DATA
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
The input DATA is used to provide the pointer to data structure of the object which is to be written.
