1) How to Write Tag Name

tagName of Point/Action is the PLC variable name (Defined by PLC program). Common forms:

• Controller Scope: MyTag
• Program Scope: Program:Main.MyTag

Naming style may differ across projects; suggest confirming variable path with vendor tools, and verifying read/write path with a "Simple Scalar Tag" first.

2) Array / UDT / Structure Support Status

Current Version:

• Scalar Type: Supported
• UDT/Structure/Array etc. Complex Types: Will return "Unsupported PlcValue type ..."

TIP

If you wish gateway side to directly support mapping Structure/Array to JSON/Binary, we can extend in future versions.
