 ===Usage===
-This activity is used to read or write a value of a single OPC variable within an [[CreateOPCUAScope (Activity)|OPC Scope]]. if ''Value'' is supplied with null, it will read the value of the variable. If ''Value'' is supplied with something else than null, it will attempt to write it to the variable.

 Is used to set the Value of the Status Code. The qualities can be divided into three main groups: Good, Uncertain, and Bad. The quality value is a 32 bit value, where the first byte represents the main quality. For Good quality thefirst byte has a value of zero (0), for uncertain quality the first byte has a value of 64, and for Bad quality the first byte has a value of 128.
 You can also use ValueQuality.GOOD, ValueQuality.UNCERTAIN or ValueQuality.BAD
