It is the first tool available on the market that supports field device integration FDI with non-proprietary, universal FDI common host components. Arburg: Complete data management via OPC UA Arburg opted for the OPC-UA application protocol for the exchange and archiving of all data and process parameters in the host computer system ALS because it can be used across manufacturer platforms and operates quickly, efficiently and reliably. The example of the process chain at the Hannover Messe demonstrated how the OPC-UA application protocol can actively be used for the data management of overarching automated production sequences. The introduction of the OPC UA client communication protocol makes the product even more appealing for integration with the level of security that the industry demands.

The specific steps are described in the following sections. DCOM is used for client-server communication, and for managing security of the connections through standard Microsoft security permissions on DCOM objects. Use the opcreset function to clear all objects from memory. If you do not supply an option, the function assumes that you want to install the components. You must type Yes exactly as shown, without any quotes.
This confirmation question is used to ensure that you acknowledge the action that is about to take place. If you receive a warning about having to reboot your computer, you must quit MATLAB and restart your computer for the changes to take effect. To successfully use DCOM, those two computers must share a common security configuration so that the two applications are granted the necessary rights to communicate with each other.
There are two configuration types described in this section: Configure DCOM to Use Named User Security describes how to provide security between the client and server negotiated on a dedicated named user basis. You do not have to be logged in as the named user in order to use this mechanism; all communications between the client and the server are performed using the dedicated named user, independently of the user making the OPC requests.
However, the identity used to run the OPC server must be available on the client machine, and the password of that identity must match on both machines. Use this option only if you are connecting to an OPC server on a dedicated, private network. You should use the named user configuration, unless your system administrator indicates that no security is required for OPC access. The guidelines provided in this section are generic and may not suit your specific network and security model.
Note The following instructions apply to the Microsoft Windows 7 operating system with Service Pack 1. Users of other Microsoft Windows operating systems should be able to adapt these instructions to configure DCOM on their systems.
To configure DCOM to use named user security, you will have to ensure that both the server machine and client machine have a common user who is granted DCOM access rights on both the server and client machines. You should consult the following sections for information on configuring each machine: OPC Server Machine Configuration provides the steps that you must perform on each of the machines providing OPC servers. On the machines hosting the OPC servers, perform the following steps: Create a new local user.
You can also create a domain user if the server and client machines are part of the same domain. The name used in these instructions is opc displayed as OPC Server in dialogs boxes , but you can choose any name, as long as you remain consistent throughout these instructions. Double-click Administrative Tools and then double-click Component Services.
The Component Services dialog appears. Right-click the OPC server object, and choose Properties. Ensure that the opc user is granted local Launch and Activation permissions. Ensure that the opc user is granted local Access permissions. In the Identity tab, select This user and type the name and password for the opc user created in step 1.
If the OPC server runs as a service, make sure that the service runs as the opc user created in step 1 and not as the system account. Consult your system administrator for information on how to configure a service to run as a specific user. Repeat steps 4 through 10 for each of the servers you want to connect to. Client Machine Configuration. Right-click My Computer and select Properties. Click OK to close the Security Limits dialog box. Click OK to close the Security Limits dialog.
Click OK. A dialog warns you that you are modifying machine-wide DCOM settings. Click Yes to accept the changes. Your local client machine and server applications are now configured to use the same username when the server attempts to establish a connection back to the client. Consult your network administrator before following these instructions.
You must complete the following steps on both the client and server machines. Ensure that the Guest user account is enabled.
The Guest account is disabled by default on Windows 7 machines. Consult your system administrator for information on how to enable the Guest account. Both the client and the server are now configured so that anybody can access any COM object on either machine. Caution This configuration is potentially dangerous in terms of security, and is recommended for debugging purposes only.
The Simulation Server is used here only for showing examples of the capabilities and syntax of OPC Toolbox commands, and for providing fully working examples.
Locally, OPC Toolbox uses a random local port number to initiate the connection. Run the installer, which automatically registers the LDS on your computer. The LDS always uses port for communication. Copy the SimulationServer. You should see an entry named SimulationServer. Based on your location, we recommend that you select:.
