nSizeOutQueue: UDINT
This variable contains the size of the data buffer to which the list of smoothed GEOINFO
structure objects will be written. This buffer must be at least five times as large as an
SMC_GEOINFO structure. If this is not the case, the ISMC_NCDecoder does not perform any
actions. It is advisable to create the actual buffer as described below, e.g. as an example :
Array of SMC_GeoInfo. The corresponding buffer size then results from sizeof(Example)
pbyBufferOutQueue: POINTER TO BYTE
This input must point to the first byte of the memory area created for the OUTQUEUE
structure. This memory area must be at least as large as defined in nSizeOutQueue. It is
typically assigned in the declaration part of the IEC program by means of an array of
SMC_GeoInfo (e.g. BUF: ARRAY[1...50] OF SMC_GEOINFO; for a buffer that can store 50
path elements). In respect of this value as well, it is permissible to set the value but it is only
permissible to alter it subsequently during a reset.
Outputs (VAR_OUT)
bDone : BOOL
This variable is set to TRUE as soon as the input data from DataIn has been fully processed.
Thereafter the program organisation unit will not execute any more actions until a reset
has been performed. If the bExecute input is FALSE, bDone will also be reset to FALSE.
bError : BOOL
This value will be set to TRUE if an error occurs.
wErrorID: SMC_ ERROR (INT)
If an error occurs, this variable will contain the error number.
poqDataOut: POINTER TO SMC_OUTQUEUE
This output points to an SMC_OUTQUEUE structure that manages rounded SMC_GEOINFO
objects.
