//+++ Call function block +++
#instMeasuringInput(MeasuringInput:=#MeasuringInput,
Execute:=(#FunctionEnable
AND NOT(#instMeasuringInput.Done)),
Mode:=0);
If a measured value was detected (instMeasuringInput.Done = True), virtually the
same function as in the simulation will run. But now the measured value detected
("instMeasuringInput.MeasuredValue1”) is entered in the "PositionTable” table.
//+++ Realize machine function +++
IF (#instMeasuringInput.Done = True)
THEN
//Get actual write index
#tempWriteIndex :=
#ProductPositionTable.WriteIndex_MeasuringInput;
//Save measured position of product on product belt
#ProductPositionTable.PositionTable[#tempWriteIndex] :=
#instMeasuringInput.MeasuredValue1;
//Generate next write index (write pointer)
//Incement index pointer
#tempWriteIndex := #tempWriteIndex + 1;
//Check modulo area of index pointer
IF (#tempWriteIndex > #ProductPositionTable.MaxIndex)
THEN
#tempWriteIndex := #ProductPositionTable.MinIndex;
END_IF;
//Write back index pointer
#ProductPositionTable.WriteIndex_MeasuringInput :=
#tempWriteIndex;
END_IF;
Note
Instead of the "MC_MeasuringInput” function and the independent restart of the
function realized in the program, this is where the "MC_MeasuringInputCyclic”
technology function can also be used.
8.3.4 Sealing unit
At the beginning of the "SynchronousOperation" function block, the current
parameters of the two technology objects used can be detected:
 Cam disc technology object:
Check bit 5 of the status word of the cam disc whether the cam disc used has
already been already interpolated for the use.
