How to create Variant Array #1416
-
|
Hi anyone knows if it is possible/how to create a variant array, an array that can store multiple datatypes like you see in the screenshot? When I do " variant_array = ua.Variant(array_values, ua.VariantType.Variant " I get " AttributeError: type object 'ObjectIds' has no attribute 'Variant' ". I've struggled with this and did not manage to find answers, any help would be apreciated! |

dv = ua.DataValue(ua.Variant([200.0, 100.0], ua.VariantType.Double)) in opcua variables and properties containing a datavalue in the value attribute of a node which containes a variant. a variant is the value + the datatype (varianttype) + information about if its an array or not and if hints about size aswell https://github.com/AndreasHeine/opcua-tutorial/blob/main/client/write.py |
