Input
|
bExecute
|
BOOL
|
|
Rising edge: starts execution.
|
|
sFileName
|
STRING(255)
|
|
File path of the file containing the g-code.
|
|
pvl
|
POINTER TO SMC_VARLIST
|
|
The variable list defines a the type and address for each variable that can be used from the g-code. If there aren't variables in the g-code, this input isn't used.
|
|
fDefaultVel
|
LREAL
|
|
Default velocity; used if the velocity (F-word) is not specified inside the CNC file. Note: only applies to the main program, not to subprograms.
|
|
fDefaultAccel
|
LREAL
|
|
Default acceleration; used if acceleration (E+ word) is not specified inside the CNC file Note: only applies to the main program, not to subprograms.
|
|
fDefaultDecel
|
LREAL
|
|
Default deceleration (E- word); used if deceleration is not specified inside the CNC file Note: only applies to the main program, not to subprograms.
|
|
fDefaultVelFF
|
LREAL
|
|
Default velocity for fast forward (G0), FF word. It is used if no velocity is specified inside the CNC file. Note: only applies to the main program, not to subprograms.
|
|
fDefaultAccelFF
|
LREAL
|
|
Default acceleration for fast forward (G0), EF+ word. It is used if no acceleration is specified inside the CNC file. Note: only applies to the main program, not to subprograms.
|
|
fDefaultDecelFF
|
LREAL
|
|
Default deceleration for fast forward (G0), EF- word. A non-negative value is expected. It is used if no deceleration is specified inside the CNC file. Note: only applies to the main program, not to subprograms.
|
|
b3DMode
|
BOOL
|
TRUE
|
If TRUE, a G17 command (activation of 3D-mode) is executed implicitly. Note: only applies to the main program, not to subprograms.
|
|
bStepSuppress
|
BOOL
|
|
When this input is TRUE, lines of the CNC program starting with ‚/’ will be ignored. Otherwise they will be processed.
|
|
aSubProgramDirs
|
ARRAY [0..4] OF STRING(174)
|
|
An array of up to 5 directories where subprograms are searched. For a subprogram with name "SUB", the file "sub.cnc" (lower-case) is searched in each of the given directories, starting with directory aSubProgramDirs[0], in ascending order. The first match is used. The first empty directory name ends the search.
|
|
bParenthesesAsComments
|
BOOL
|
TRUE
|
Usually, parentheses in g-code are treated as multi-line comments. If bParenthesesAsComments is set to FALSE, however, parentheses can be used in the usual ways to group expressions ('(a+b)*c') and for subprogram calls ('N10 sub(17)') in g-code. Multi-line comments can be started with '(' and end with ')'.
Note
Regardless of the value of this input, it is always possible to use curly braces '{}' to group expressions and for subprogram calls.
|
|
bDisableJumpBuffer
|
BOOL
|
|
This input, if TRUE, disables an internal jump buffer that is used to improve performance of g-code processing if jumps (G20) are used.
|
|
Output
|
bBusy
|
BOOL
|
|
TRUE while execution of function block is not finished
|
|
bError
|
BOOL
|
|
TRUE signals that an error has occurred within the function block.
|
|
ErrorID
|
SMC_ERROR
|
|
Error identification
|
|
errorPos
|
SMC_NC_SourcePosition
|
|
The source-position where an error has been detected.
|
|
ErrorProgramName
|
STRING
|
|
The name of the program where an error has been detected
|
|
sentences
|
SMC_GSentenceQueue
|
|
The output sentence queue that can be fed into SMC_NCInterpreter.
|
|
adwFileSize
|
ARRAY [0..(NUM_PARSER_CHAINS - 1)] OF DWORD
|
|
Size of the file in bytes.
|
|
adwPos
|
ARRAY [0..(NUM_PARSER_CHAINS - 1)] OF DWORD
|
|
Current Position of the cursor in the file.
