2.6.1 Type conversion (L_ByteArrayToDint)

This FB converts a 4−byte array into a variable of type DINT.

VariableName DataType SignalType VariableType Note

abyIn Byte [0 ... 3] VAR_INPUT

dnOut Double−integer VAR_OUTPUT

2.6.2 Type conversion (L_DintToByteArray)

This FB converts a variable of type DINT into a 4−byte array, as, for instance, the FB L_ParWrite

expects for the input abyData.

VariableName DataType SignalType VariableType Note

dnIn Double−integer VAR_INPUT

abyOut Byte [0 ... 3] VAR_OUTPUT

2.6.3 Code index (L_FUNCodeIndexConv)

This function checks the value range 1 ... 8000 of a code index and transmits the index to, e. g. the

FB L_ParWrite via the wIndex input. If the code numbers are invalid, the function transmits the

0000 index.

VariableName DataType SignalType VariableType Note

wCodenumber Word VAR_INPUT
