Chapter4. How to create a cMT-G01/G02 project
This chapter explains how to create a project when cMT-G01/G02 is used as an OPC UA Server, and how to set the addresses used to communicate with OPC UA Clients. The basic steps are:
- Add a driver into Device List in EasyBuilder Pro.
- Enable OPC UA Server and designate communication address.
- Download the project to HMI.
The following explains how to set up OPC UA Server in the project.
4.1. Create a new project
Step 1. Launch EasyBuilder Pro and select a cMT-G01/G02.
Step 2. Add a PLC into the Device List.
Step 3. Click [IIoT] » [OPC UA Server], and select [Enable] check box to enable OPC UA Server.
Step 4. Click [Tags] of the device and then click [New Tag] to add tags monitored using OPC UA.
When finished, click [OK] to leave.
Step 5. Find the created tags in OPC UA Server window. Larger quantity of tags can be exported as csv/excel file and then imported for editing.
4.2. Download project to cMT-G01/G02
The format of the project file run on cMT-G01/G02 is *.cxob. In EasyBuilder Pro, click [Project] » [Compile] to compile the project into *.cxob format. When finish compiling, you can download the project to cMT-G01/G02 by two ways.
Way 1: Download using EasyBuilder Pro. Click [Project] » [Download], and set HMI IP address. The project can be downloaded via Ethernet.
Way 2: Download using website. Open internet browser (IE, Chrome, Firefox), enter cMT-G01/G02 IP address (for example: 192.168.100.1), click System Setting, enter password, and then configure cMT-G01/G02 settings. Go to [Project Management] page and open [Upload Project] tab to download the project file from the computer to cMT-G01/G02.
4.3. Monitoring OPC UA Client
After downloading the project file to HMI, use OPC UA Client software to connect with cMT-G01/G02 to monitor PLC data.
Note: The above is a screenshot of UaExport settings window, for more information on OPC UA Client software settings, please see software’s manual.
4.4. On-line/Off-line Simulation
Running On-line or Off-line simulation in EasyBuilder Pro helps you examine OPC UA Tag settings. In On-line simulation, cMT Diagnoser can read from / write to PLC. Please note that On-line simulation is limited to 10 minutes.
Step 1. In EasyBuilder Pro click [Project] » [On-line Simulation] / [Off-line Simulation] to open cMT Diagnoser window.
Step 2. Add the tags to be previewed into the Monitor list on the right side.
Step 3. In On-line Simulation, data in PLC tags will also change.

Chapter6. OPC UA Web Management Interface
6.1. Introduction
cMT-G01/G02 provides a web-based tool for convenient access to OPC UA configurations.
Open cMT-G01/G02’s webpage by entering its IP address into the address bar of a web browser. At the entry page, log in with System setting’s password. Factory default of the password is 111111.
(Suggested resolution: 1024×768 or higher)
Navigate to the OPC UA configuration page from the context menu on the left.
The OPC UA configuration page consists of a Startup/Shutdown control with status bar and tabbed windows including: Server settings, Edit node, Certificates, Discovery, and Advanced.
Usage of each window tab:
| Tab | Description |
| Server settings | Configure server settings such as port, name, security, user authentication……etc. |
| Edit node | Manage tags used by OPC UA server. |
| Certificates | Manage certificates used by OPC UA server. |
| Discovery | Manage list of discovery server. |
| Advanced | Advanced options and features. |
6.2. Startup / Shut Down
Use the toggle button to start up or shut down the OPC UA server. If there is active client connection, when shutting down, the server will wait for a few seconds before closing off completely.
In addition, both the toggle button and a line of text also indicate the status of the server. The status is refreshed approximately every 10 seconds. An icon on the right 
indicates that the status is being refreshed.
Endpoint URL is also displayed for user’s reference.
*Whenever a page refresh is desired, use the menu on the left. Avoid using the browser’s refresh button to reload a tab as you may be asked to enter the password to log in again.
6.3. Server Settings
The Server settings page shows general configurations of the OPC UA server.
| General | Function |
| Port | Access port of the OPC UA server |
| Server name | Server name of the OPC UA server |
| Security policy | Supported security policies. At least one must be selected. Supported Policy: None, Basic128Rsa15, Basic256, Basic256sha256 Mode: Sign, Sign & Encrypt |
| Option | Automatically Trust all client certificates: by enabling this option, the OPC UA server will trust the certificate from any client connection. |
OPC UA server must be configured with at least one user authentication mode as listed in the following table.
| Authentication | Descriptions |
| Anonymous | Allow anonymous client connection. At least one of Browse, Read, or Write modes must be selected. |
| User name & Password | Allow user authentication with username and password. Each access mode, browse, read, and write can be assigned to a user class. User classes are configured in the Enhanced Security mode on the web interface or in EasyBuilder Pro. |
| Certificate | User authentication with X.509 certificate |
After completing settings, click the Save button to save the changes. OPC UA server will shut down momentarily and then restart for the changes to take effect.
6.4. Edit Node
In this page, the user can view and manage the tags currently available in the OPC UA server. New nodes and groups can be added, while existing nodes and groups can be edited or deleted. For ease of navigation, detail information of the currently selected node/group is displayed on the right. After completing settings, it is necessary to click the Save button to save the changes. OPC UA server will shut down momentarily and then restart for the changes to take effect. Changes will be lost if one exits this page without saving.
Note that all modifications can only be made for existing drivers. It is not possible to change or add other drivers that are not already available. It is also not possible to edit the nodes used by tag PLCs*.
*Tag PLCs are characterized by their use of name tags as device memory address as opposed to using device name with indices. Examples of tag PLCs include: BACnet, Rockwell Free Tag Names , Siemens S7-1200,…etc.
6.5. Certificates
In this page, the user can manage certificates and revocation lists of the OPC UA server. Use the dropdown menu to access each page.
If “Allow anonymous client connection” (in the Server settings tab ) option is not active, OPC UA server will reject all client connections and place their certificates in the untrusted list. User may manually “trust” them in this page. Use the reload button to repopulate the list of certificates if necessary.
Similarly, currently trusted certificates can be manually rejected on the same page.
| Page | Description |
| Trusted Clients | Lists of trusted/rejected client certificates on the server. Supported operation: Trust/Reject, Remove, Import, Export. |
| Trusted Users | Lists of trusted/rejected user certificates on the server. Supported operation: Trust/Reject, Remove, Import, Export. |
| Own | Server’s own certificate. Supported operation: Update, Remove. When updating own certificate, matching certificate and Private Key must be uploaded together; otherwise, update will fail. A self-signed, 20-year validity certificate will be generated automatically if own certificate is absent when server starts up. |
| Trusted Client Issuers | List of trusted client issuer certificates. Supported operation: Import, Remove, Export. |
| Trusted User Issues | List of trusted client issuer certificates. Supported operation: Import, Remove, Export. |
| Certificate Revocation List | Certificate revocation lists for client, user, client issuer, and user issuer. Supported operation: Import, Remove, Export |
6.6. Discovery
OPC UA server can register itself with Local Discovery Servers. In this page, the user can maintain the list of discovery servers that OPC UA server will register with during startup. Should the discovery server be unavailable during server shutdown, the shutdown process will be slightly delayed.
After completing settings, click the Save button to save the changes. OPC UA server will shut down momentarily and then restart for the changes to take effect.
6.7. Advanced
Additional settings can be configured in the Advanced tab. The user can set the trace logging level and specific startup behavior of the OPC UA server. Furthermore, the trace log can be downloaded.
After completing settings, click the Save button to save the changes. OPC UA server will shut down momentarily and then restart for the changes to take effect.
