 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).  | 
 Outputs 
VAR_OUTPUT
    bBusy     : BOOL;
    bErr      : BOOL;
    nErrId    : UDINT;
END_VAR Name  | Type  | Description  | 
|---|---|---|
bBusy  | BOOL  | This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'Timeout' input. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.  | 
bErr  | BOOL  | This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in 'nErrId'. Is reset to FALSE by the execution of a command at the inputs.  | 
nErrId  | UDINT  | Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. The error numbers in ErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).  |
