SWA UA Client User Guide

---

SWA UA Client, as a testing assistant for OPC UA, provides encrypted sessions based on X509 certificates for server discovery, connection, and browsing. It supports data reading and writing based on access permissions, integrates image view and chart view, handles all types of scalar, array, matrix, and complex structure data, and supports data monitoring, events, methods, and historical data reading and chart display. Optional tracking and recording are also supported, including error, general information, stack, service calls, operation class, and security class information.

Server Connection Page

• First Connection: Enter the server address to obtain and select connection points. Choose the available authentication method during authentication, enter the username and password as needed, then click the Connect button.
• Saved Connections: Successfully connected connection points and their configurations will be saved locally for easy reconnection. Choose from the dropdown list and click the Connect button.

Saved connections are only available for guest identity (Anonymous), and usernames and passwords are not saved locally.

Server Browsing Page

[1]. Open/close browsing
[2]. Manually enter NodeId to read node information

Cards Functions

• Nodes - Node tree
• Manual - Manual input
• Image Value - Image display
• Attributes - Feature list of selected or entered nodes
• Properties - Property list of selected or entered nodes
• References - Reference list of selected or entered nodes
• Reference Attributes - Feature list of references selected in the References card area

Reading and Writing Data

In the Attributes feature list, Value is displayed with the data structure of its Value. Double-click the Value row to open the write dialog.	Modify items and click the Write button to write (gray indicates that the node Value is not writable).

*After writing, the node Value needs to be reread to display the new value.
*Array dimensions and length modification are not supported.

Intermediate Operations in the Node Pallet

The Node Pallet serves as an intermediate container for node selection and connection between browsing and control panels. It aggregates nodes of different types in the same task group, allowing batch addition to the control panel. It supports multiple reuse and duplicate checks within the group. When selecting nodes to add to the control panel, duplicate checks are performed.

In the Browsing server's node card, select the node to operate and drag it to the group in the node Pallet.

The right side of the node item in the node tray contains a pop-up menu 。

Menu	Purpose
	Display node information
	Add the node to the Monitor panel's value monitoring area
	Add the node to the Monitor panel's Trigger control area
	Add the node to the Event panel
	Add the node to the Method panel
	Add the node to the History panel
	Delete the node (only removes it from the node tray)

Bulk Add to Operation Panel: Each group has a one-click add node button , Clicking this button adds all available nodes in the group to the corresponding control panel. Nodes that can be added with one click are events (Event), methods (Method), and historical data (History). Monitor Value / As Value Trigger must be manually added to the Monitor panel for their intended purpose.
