value = instance.WritableSourceTimestamp

Property Value

true if the source timestamp is writable; otherwise, false.

The default value of this property is False.

Remarks

Setting this to false (the default) restricts write access to the source timestamp by OPC clients, making it read-only.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
