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

Represents a String value (in PLC a STRING) its value defines a series of characters.

C# 

public class PlcString : PlcValue<string>, IPlcValue<string>, IPlcValue, IPlcSymbol, IPlcEntity, IPlcStatusProvider, IPlcRelocatable<IPlcValue>, IPlcRelocatable, ISupportInitialize, IEnumerable<char>, IEnumerable


Inheritance Object › PlcValue<String> › PlcString


Implements IPlcValue<String>, IPlcValue, IPlcSymbol, IPlcEntity, IPlcStatusProvider, IPlcRelocatable<IPlcValue>, IPlcRelocatable, ISupportInitialize, IEnumerable<Char>, IEnumerable

Remarks

While a PLC value of this type represents a String value, all PLC operations performed using this class are done using the Byte. A PLC developer knows a value of this type as STRING.
