WebIQ does not support arrays per se as an array structure (data type) and ExtensionObjects in OPC-UA. We have not yet implemented this, but we are aware of it and it is on the roadmap, but I can't give you a date when it will be available. WebIQ can only work with individually addressable items and does not understand the semantics of an array. Therefore, for WebIQ, a value such as "temperatures[4]" is exactly the same as a value such as "act-value". Each individual data point must be uniquely addressable via an identifier using OPC UA, so in the case of an array, each individual array element must be directly addressable as an individual element using OPC UA and not just via the array type. Depending on the OPC UA server, this can be achieved by activating an option such as "FolderType" or similar - unfortunately there is no standardized name for this. Each array and structure element must be individually addressable via OPC UA. You can then use the "Variables" and "Structures" tabs in Process Data Manager to map the structure of your system. WebIQ then generates a flat structure of items from this, which you can find in the "Items" tab - only these can be connected to widgets. You will therefore only find basic data types such as integer, float and string there.
