Summary

OPC Unified Architecture (OPC UA) is a cross-platform, open-source, IEC62541 standard for data exchange from sensors to cloud applications developed by the OPC Foundation. The UA in OPC UA stands for “Unified Architecture” and refers to the latest specification of the standard. It differs from its predecessor in that it is platform-independent, moving away from COM/DCOM to purely binary TCP/IP or alternatively SOAP.


This manual page provides an overview of the OPC UA functionality in RUTX12 devices.

Note: OPC UA is additional software that can be installed from the System → Package Manager page.

OPC UA Configuration

The OPC UA Configuration section is used to enable the service.

Field Value Description
Enable off | on; default: off Enables OPC UA service.
Port integer[1..65535]; default: empty Enables service port.

OPC UA Servers

The OPC Server is the basis of OPC communication. It is a software that implements the OPC standard and thus provides the standardized OPC interfaces to the outside world. To add a new server, enter an instance name and click the 'Add' button.

After clicking 'Add' you will be redirected to the newly added server's configuration page.

OPC UA Server Configuration


The OPC UA Server Configuration section is used to configure the parameters of an OPC UA Server.

Field Value Description
Enable off | on; default: off Enables specific OPC UA server instance.
Name string; default: none Name of the server, used for management purposes only.
URL url; default: none Specifies OPC UA endpoint URL.
Timeout integer [10..3600000]; default: none Specifies server timeout in ms.

OPC UA Server Nodes


A node is the basic unit of data in the OPC UA address space, which provides a standard way for OPC UA servers to represent objects to OPC UA clients. Nodes are pieces of information (for example, a unique temperature) and consist of attributes, the actual data value, and one or more references to other nodes, each in its own address space. A unique temperature will therefore take up multiple addresses in an address space.

By default, there are no nodes configured. To add a new server node, enter an instance name and click the 'Add' button.

Field Value Description
Name string; default: none Name of the node instance, used for management purposes only.
ID namespace integer [0..65535]; default: none Specifies node ID namespace.
ID type Numeric | String | GUID | Bytestring; default: Numeric Specifies node ID type.
ID dynamic; default: none Specifies node ID (validation varies depending on ID type).

OPC UA Value Groups

A Value Group is a collection of different specific group values. Each value configured under this group will be returned inside the same group array.

By default, there are no value groups configured. To add a new group, enter an instance name and click the 'Add' button.

Field Value Description
Enable off | on; default: off Enables specific OPC UA value group instance.
Name string; default: none Name of the value group instance, used for management purposes only.
Scheduling type Period; default: Period Specifies method of scheduling data retrievals.
Period integer [1..86400]; default: none Specifies time duration between data retrievals in seconds.
Failure mode None | Any | All; default: None
Failure storage off | on; default: off Whether to store results of a failure.
Failure replacement string; default: none Results of a failure will be replaced by this string
Prefix string; default: none String going before all the values.
Midfix string; default: none String going between all the values.
Postfix string; default: none String going after all the values.

OPC UA Group Values


A Group Value is a specific value retrieved from a defined server node.

Field Value Description
Enable off | on; default: off Enables specific OPC UA value instance.
Name string; default: none Name of the group value instance, used for management purposes only.
Prefix string; default: none String before the value.
Postfix string; default: none String after the value.
Replacement string; default: none String to replace everything in case of failure.
Server to retrieve data from OPC UA server instance; default: none Specifies which server to retrieve data from.
Server node OPC UA server node instance; default: none Specifies which server node to retrieve data from.
