Represents the largest possible value of a PlcDateTime.
C#
public static readonly DateTime MaxValue
Field Value
DateTime
Remarks
The according PLC value would be: DT#2089-12-31-23:59:59.999.
Represents the smallest possible value of a PlcDateTime.
C#
public static readonly DateTime MinValue
Field Value
DateTime
Remarks
The according PLC value would be: DT#1990-1-1-0:0:0.0.

specified.
C#
protected override DateTime GetValueCore(PlcDeviceConnection connection)
Parameters
connection
PlcDeviceConnection
The PlcDeviceConnection from that the data is to be retrieved.
Returns
The current value of the PLC value.
Exceptions
The connection
is in Faulted state and cannot longer be opened.
The connection
has been disposed of.
Determines whether the provided value is accepted for the type of PLC value through basic type checking and also potentially if it is within the allowed range of value for that type.
C#
public override bool IsValidValue(object value)
Parameters
value
Object
The value to check.
Returns
The value true, if the specified value
is acceptable and is of the correct type or a derived type; otherwise the value false.
