OPC UA Client and OPC UA Server can run simultaneously on the same cMT series HMI. The user can add multiple OPC UA Clients on one HMI, and can use the same HMI to connect to multiple OPC UA Servers. Multi-dimensional: Scalar, Arrays, Matrixĭata types: BOOL, BINARY, SINT, INT, DINT, REAL, LINT, BYTE, UDINT, WORD, DWROD, UINT, STRING The selected items will be added to the list on the right side, and be imported. As shown in the following screenshot, select the tags from the list on the left side, and then click. Users can select the tags to be imported. The tags can be exported to other HMI projects by clicking. Way 1: Click to connect to OPC UA Server and get tag information. There are two ways to get tag information: In System Parameter Settings » Device List, select OPC UA Client. Subscription: The client queries nodes on the OPC UA Server in a specified interval, and reads data only when data changes. Request: Client will not stop reading data from the Server. Session name: When the Client is connected to the Server, the messages from the Client can be seen on the Server.

If not using the certificate and private key on HMI, the certificate (.cer) and private key (.pem) generated by OpenSSL from the server should be imported, and then enter private key password if it exists. Message security mode: Select the same mode as the server.Īuthentication: Select from, , or.Security policy: Select the same policy as the server.Server name: For certain servers, server name is required for communication. In device property settings click and configure PLC communication parameters as shown in the following screenshot.Įnter IP address and port number, and then click. Launch EasyBuilder Pro, in System Parameter Settings, add OPC UA » OPC UA Client. In this architecture, the user can run OPC UA Client on HMI, and use it to access data in OPC UA Server (implemented on cMT Series models), to receive data updates of the PLCs connected to HMI, regardless of which PLC brand is implemented. The following is an example of OPC Unified Architecture. Recommended OPC UA Server: Weintek OPC UA Server, Unified Automation, Prosys, Kepware.
