Syntax

=OPCUA.VARIABLES(Range)

Formula	Result	Comment
`=OPCUA.VARIABLES(OPCUA.JSON(B3:C8))`	"TRUE"	The two rows are needed to define the variable name and its value. The amount of columns is flexible, depending on the amount and structure of the variables needed. The Range will automatically assume a structure and settings.
