Inputs/Outputs
VAR_IN_OUT
sNciToPlc : NCTOPLC_NCICHANNEL_REF;
END_VAR Name | Type | Description |
|---|---|---|
sNciToPlc | NCTOPLC_NCICHANNEL_REF | The structure of the cyclic channel interface from the NCI to the PLC. This structure is read-only (type: NCTOPLC_NCICHANNEL_REF). |
Return value
Name | Type | Description |
|---|---|---|
ItpIsFastMFunc | BOOL | The function returns TRUE if the fast bit of the M-function is set. |
 | ItpIsFastMFunc evaluates the variable 'nFastMFuncMask' from the cyclic interface. |
Example
