ItpGetGeoInfoAndHParamEx
The function block ItpGetGeoInfoAndHParamEx reads informations of the currently active segment and past and future segments. These include block number, H-parameter and residual path length on the segment.

sNciToPlc : NCTOPLC_NCICHANNEL_REF;
END_VAR
sNciToPlc: The structure of the cyclic channel interface from the NCI to the PLC. This structure is only accessed for reading. (type: NCTOPLC_NCICHANNEL_REF)

END_VAR
stTab: Structure containing the segment data. See ST_ItpPreViewTabEx.
nErrId: 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 nErrId can be looked up in the ADS error documentation or in the NC error documentation (error codes above 0x4000).

nDcTime : UDINT := 0
nReserved : UDINT := 0;
arrLines : ARRAY[1..NCI_MAX_PREVIEWTABLINES] OF ST_ItpPreViewTabLine;
END_STRUCT
END_TYPE
nDcTime: Current time stamp in ns. This time stamp can be used e.g. in interplay with the Tc2_NciXFC library.
arrLines: Array of segment-related information (size 20). The entry at position 11 of the array corresponds to the currently active segment. Segments that have already been processed are displayed at positions 1-10 of the array, future segments at positions 12-20. See ST_ItpPreViewTabLine.
TYPE ST_ItpPreViewTabLine :
STRUCT
fLength : LREAL := 0.0;
nBlockNo : UDINT := 0;
nHParam : UDINT := 0;
nEntryID : UDINT := 0;
nReserved : UDINT := 0;
END_STRUCT
END_TYPE
fLength: Remaining segment length. For segments that are not yet active this corresponds to the total segment length. For past segments the distance moved since the end of the segment is specified.
nBlockNo: Block number programmed by the user
nHParam: Value of the H-parameter that is active from the start of the next segment
nEntryID: Command ID generated by the system
