PlcLReal Class

Namespace: IPS7Lnk.Advanced
Assemblies: IPS7LnkNet.Advanced.dll

Represents a Double value (in PLC a LREAL) its value defines a double-precision floating-point number.

C#

public class PlcLReal : PlcValue<double>, IPlcValue<double>, IPlcValue, IPlcSymbol, IPlcEntity, IPlcStatusProvider, IPlcRelocatable<IPlcValue>, IPlcRelocatable, ISupportInitialize


Inheritance ObjectPlcValue<Double> › PlcLReal


Implements IPlcValue<Double>, IPlcValue, IPlcSymbol, IPlcEntity, IPlcStatusProvider, IPlcRelocatable<IPlcValue>, IPlcRelocatable, ISupportInitialize

Remarks

While a PLC value of this type represents a Double value, all PLC operations performed using this class are done using the LWord. A PLC developer knows a value of this type as LREAL.
