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).
