Hi, the subsequent interpreter should report an error? The reader is just reading the file without checking the syntax.

Thank you for answering my question. I am sharing some POU's and the IPO screenshot below. I thing this should do the job.
Could you tell me what I am missing?
//Interpreter PRG
IF gCNC.bCycleStart THEN
bOldExecute := TRUE;
gCNC.bTaskCompleted :=FALSE;
END_IF

IF gCNC.bCycleStop THEN
bOldExecute := FALSE;
gCNC.bTaskCompleted :=TRUE;
END_IF

//Read File
fbReadFile(bExecute := bOldExecute,
sFileName := strFileName,
fDefaultVelFF := 50.0,
fDefaultAccelFF := 30.0,
fDefaultDecelFF := 30.0,
ErrorID => gCNC.eErrorId,
errorPos => gCNC.eErrorPos,
ErrorProgramName => gCNC.eErrorProgName
);

//Interpret the file
fbInterpreter(Sentences := fbReadFile.sentences,
bExecute := bOldExecute,
bAbort := gCNC.bCycleStop,
nSizeOutQueue := SIZEOF(astGeoBuffer),
pbyBufferOutQueue := ADR(astGeoBuffer),
GCodeText => sGCodeText);

//Check Velocities
fbCheckVel(bExecute := fbInterpreter.bDone,
bAbort := gCNC.bCycleStop,
poqDataIn := fbInterpreter.poqDataOut);

pGeoInfos := fbCheckVel.poqDataOut;
bDone := fbInterpreter.bDone;

IF bDone THEN
bOldExecute := FALSE;
gCNC.bTaskCompleted :=TRUE;
END_IF

//Interpolator PRG

IF LicOS_EtherCAT.xConfigFinished THEN
gCNC.bAxesEnable := TRUE;
END_IF

IF X_Axis.bCommunication AND Y_Axis.bCommunication AND Z_Axis.bCommunication AND gCNC.bAxesEnable THEN

fbZPower(Axis :=Z_Axis,
    Enable := TRUE,

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Hello,

I’m using CODESYS V3.5 SP18.
When I try to use SMC_ReadNCFile2 to read the file /PlcLogic/gcode.nc, the function block's bBusy output remains TRUE indefinitely.
Can you help me understand what I might be doing wrong?

Here is how I’m calling the function block.
The value of strFileName is 'gcode.nc'.

fbReadFile(
bExecute := bExecute,
sFileName := strFileName,
bAbort := bCycleStop,
fDefaultVel := RetainVariables.xSlowVelocity,
fDefaultAccel := RetainVariables.xAcc,
fDefaultDecel := RetainVariables.xDec,
b3DMode := TRUE,
bParenthesesAsComments := TRUE,
fDefaultVelFF := RetainVariables.xFastVelocity,
fDefaultAccelFF := RetainVariables.xAcc,
fDefaultDecelFF := RetainVariables.xDec,
ErrorID => gCNC.eErrorId,
errorPos => gCNC.eErrorPos,
ErrorProgramName => gCNC.eErrorProgName,
bBusy => bReadFileBusy,
sentences => sentencesss
);
Thanks in advance for your help.
