You can choose between identities based on username/password or a certificate (X509). However, if a server is expecting additional information about the user identity other than the client certificate, a user identity has to be set. If the server supports anonymous user identity, no additional configuration is required. If required, you can configure the path to all certificates stores through the console or a cfg file. On OPC UA it's applied to node ID.Ĭompatibility of OPC UA Data Types ¶ Tag Data TypeĪ Bool tag mapped to the following data types is automatically converted to a number: SByte, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double (true = 1, false = 0)Īn Int tag mapped to a Boolean node is automatically converted (value != 0 : true otherwise, false)Ī Float tag mapped to a Boolean node is automatically converted (abs(value) >= 1 : true otherwise, false)īy default certificates are loaded from Installation Folder\CertificateStores. On OPC Classic this filter is applied to item's ID. Only retrieves nodes that contain the specified value. On OPC UA it's applied to node display name. Only retrieves nodes that start with the specified value. The maximum number of nodes that will be retrieved from the server (max 256). Alternatively, enter the OPC server endpoint Url (or ProgID when using OPC Classic) and press Enter.Ĭlick to browse nodes on the current OPC server. Select the OPC server to connect to from the list.

opc.tcp:// hostname for browsing OPC UA servers.

Leave blank when browsing for local servers.

Name of the machine where to browse for OPC servers. On OPC UA, Starts width filter is applied to node display name and Contains filter is applied to node ID. On OPC Classic both filters are applied to item's ID. These filters are implemented differently on OPC Classic and OPC UA. 'fio_') you can use the Start with and Contain filter to retrieve only these nodes from the server. Additionally, by adding a prefix to these nodes (e.g. It's a good practice to start the name of sensor nodes with a letter and actuator names with another, for example, the letter 'i' (input) for sensors and 'o' for actuators.īy doing so, sensor items are displayed together and before actuators (see image above). This means that you should choose the appropriate data type and read/write permissions when creating nodes on the server. You may link any tag to any node, independently of the tag data type or if it's a sensor's or actuator's tag.

Note that only nodes names are displayed - hover the mouse cursor over a node to show the full node ID (or item ID when using OPC Classic). You will find the Total Number of discovered nodes next to the server name, which you can limit by choosing a Limit (see below).

These nodes are browsed from an OPC server by clicking on the BROWSE button, which are then displayed alphabetically on the Driver window.

The OPC UA driver supports only the opc.tcp scheme.Īctuator and sensor tags are mapped to OPC items/nodes, depending when you are using OPC Classic or UA - throughout this document, items/nodes will be referred just as nodes.
