A device-specific window is displayed for each device link: Server Status List Siemens TCP/IP Channel Redundancy Group S7 ISO on TCP Connection S7 NetLink Connection Creating and Configuring a Server Status List Object Some OPC clients use the OPC call, GetServerStatus(), to monitor the state of an OPC server. MatrikonOPC‟s Server Status List object makes it possible to monitor an OPC server status in a customizable way. The Server Status List object contains a list of subscribed device links that can exist anywhere in the OPC server hierarchy. The status of the server is checked every configured status check period by examining the status of the subscribed device links. Device links can be added to the Server Status List in one of two ways: 1. Direct – the device link is added directly to the subscription list. 2. Parent – the device link‟s sub-ordinates are added to the subscription list. There are two options for the logic that will determine the server status. For the Server Status to be Running, the first option requires that there is at least one subscribed device link that is running. In this case, if all subscribed device links enter a failure condition (e.g., become disconnected), the Server Status will be Failed. The second option is stricter as it is required that all subscribed device links be running. In this case, if any subscribed device links enter a failure condition, the Server Status will be Failed. Multiple Server Status Lists can exist and there can be one or more device links contained within a Server Status List. There is no restriction on having a particular device link contained within more than one Server Status List. The Create New Server Status List window (Figure 26) displays the settings available for configuring a Server Status List object.

It is usually simpler to install and configure servers as a user with local administrative rights. the better the chances of connecting to an OPC server on an unknown remote machine (such as at an OPC Interoperability Workshop). Server Identity The Identity tab for a selected COM (or OPC) server specifies the user account that should be used when COM starts up the process. the server can be set to run as a specified user. MatrikonOPC Server for Siemens PLCs v1. The more protocols that appear in the list. It is usually best to use the interactive user or a specified user. click OK to close the Add Users and Groups window.12. it may also take longer for DCOM to time out if a server machine is not present since it has to try each protocol in turn. However. You can then choose to Allow Access or Deny Access for each user. The order that protocols appear in the list indicates the priority in which they will be used (the topmost having the highest priority). The Configuration Permissions contain an Access Control List of principals that are allowed to modify the configuration information for a server. or a specified user. but instead of choosing Allow Access for a user you would choose Allow Launch. In other words. it indicates who is allowed to alter the registry entries for installed servers as well as who is able to access the registry for the purposes of installing new servers. the interactive user (the one currently logged onto the machine). add the local user on the OPC server to the DCOM permissions. Contact your IT personnel for more information about your network. It also adds a greater degree of security in terms of who is able to shut down the server process.0 User’s Manual 119 . Notes: The procedure to set the launch permissions is similar to the above. it is best to remove all unused protocols from the list and only include those that are necessary for your network. When you are done adding users. To connect to an OPC server from outside of the domain. create a local user account on both the server and the client machine with identical username and password. Servers that run as NT services should generally run as the local System account. For example. although this is usually done from the Service Control Manager applet rather than DCOMCNFG. on a TCP/IP network. The available settings are different for servers that run as local executables as opposed to those that run as NT services. Alternatively. Note: It is strongly recommended that OPC servers should be installed to run as NT services if they are going to be accessed by remote clients via DCOM. Then. This ensures that the server can always be accessed even if no one is presently logged on to the machine. and only one server process ever starts up. Access and Launch permissions are particularly important when installing a server to run as an NT service. 13. Servers that run as local executables have the option of running as the launching user (the calling client–this is the default). Default Protocols The Default Protocols tab specifies the communication protocols available to DCOM.3. remote clients might start up multiple separate server processes that are not accessible to others. Use the local account on the client machine to connect to the OPC server. Otherwise. For most situations. 6. run REGEDIT on the client machine and choose Import Registry File from the Registry menu.

Merge the REG files into the registry of the client machine. 7. Expand the HKEY_CLASSES_ROOT key. use the following steps to copy a program ID to the client machine. 8. some older OPC clients need to have a program ID in the local registry in order to connect to a particular OPC server. Delete the REG files since they are no longer needed.3. Please check the client documentation for more information. For each program ID. Therefore. OPC client applications had to search the registry to generate a list of available OPC servers. the ID has the form Matrikon. run REGEDIT as a user that has access rights to the local registry. 9. Back up your registry. it is strongly recommended that these protocols be removed from the list of default protocols. 5. Be careful not to overwrite other export files that you are creating. Note: This method may not work for every OPC client. WARNING: Any changes made to the registry must be made with extreme caution! 1. Note: In the case of Matrikon OPC Servers. Find the program ID(s) for the desired OPC server(s). The simplest solution is to install the OPC server software on the client machine even if it is not used. MatrikonOPC Server for Siemens PLCs v1.

OPC Security Implementation Whether a user has access or not will depend on: 1. and other important details.Appendix F Introduction Security The OPC Framework has implemented the OPC Security Customer Interface version 1. 3. Appendix Structure This appendix is structured as follows: Introduction – this introductory section. the OPC client must implement and follow the OPC Security specification in terms of following the calls necessary to provide credentials. and is able to do so by setting permissions for a partial item ID or path. The OPC client may choose to log off. Location Some of the interface calls made from an OPC client to an OPC server require the client to provide an OPC item ID. The type of functionality in an OPC server that is controlled by OPC Security is vendor-determined. since no interface calls are necessary. A particular server installation may want to control access to a particular device or branch in the hierarchy. how security settings are stored. the OPC client must make a call to the OPC server to log on with a user name and password. OPC Security Implementation – description of user access dependencies. The OPC Security specification defines how user credentials are passed from client to server.3. In this scenario. the identity of the OPC client is the domain user that is running the OPC client and connecting to the OPC server.0 User’s Manual 131 . and use the name from those credentials for access control. This method does not require any implementation of OPC Security by the OPC client. Type – the type of functionality the user is trying to perform. 2.

Reading. The MatrikonOPC Tag Security Configuration Utility is a component of an OPC server installation. Note: In order for the MatrikonOPC Tag Security Configuration Utility to work properly. a tool that is installed with the server. A location that is being accessed by an OPC client may have different permissions for the different types of access. then it will configure security for the OPC server to which the shortcut belongs. the following: Who has permission Which tags/locations they have permissions for The type of permissions for those locations Security settings configured using this utility are read by the OPC Framework and populated in memory upon server start-up. reading values from the items. When browsing. or from a shortcut found in the Start Menu.exe The MatrikonOPC Tag Security Configuration Utility can be run either directly from its installed location. read control has been added to group subscriptions call-backs as well as synchronous reads and asynchronous reads – denying read control would disable reads for the possible types.

The #MonitorACLFile is a boolean OPC tag that has a default value of True when the server starts which indicates that the tag security permissions are monitored and applied while the server is running.
