Description

Immediately

Writes the values of this DynamicValue instantly when setting its value or the value of its child members/elements.

Triggered

Caches internally the value of this DynamicValue until the DynamicValue.Write method is called. This reduces ADS rountrips, if one or more member/element values should be changed. Furthermore the write on the destination system happens consistently in one ADS Write operation, which could be important for dependent properties/members/elements.
