PlcTime Class

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

Represents a TimeSpan value (in PLC a TIME) its value defines an time interval.

C#

public class PlcTime : PlcValue<TimeSpan>, IPlcValue<TimeSpan>, IPlcValue, IPlcSymbol, IPlcEntity, IPlcStatusProvider, IPlcRelocatable<IPlcValue>, IPlcRelocatable, ISupportInitialize


Inheritance ObjectPlcValue<TimeSpan> › PlcTime


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

Remarks

While a PLC value of this type represents a TimeSpan value, all PLC operations performed using this class are done using the DWord. A PLC developer knows a value of this type as TIME. The time interval of this type typically supports a negative number of days, but because of TimeSpan does not support a negative number of days a negative number will be changed into a positive one by this implementation.
