OPC UAData Connection

Easy Connection of Real-Time Machine Data with Data from CRM and ERP Systems.

In a modern landscape, OPC Unified Architecture, OPC UA for short, represents the secure universal solution in machine communication. This protocol is based on the specification of the OPC Foundation and is supported by practically all well-known manufacturers of machines, conveyors or microcontrollers (e. g. Siemens, Beckhoff, Bosch Rexroth etc.).

Peakboard can handle a variety of data sources. Access to databases, Excel, social media and ERP systems such as SAP and Dynamics NAV are part of Peakboard’s standard repertoire. No less exciting and elegant is the access to machine data. Even in this environment, Peakboard offers several options of which the use mainly depends on the environment, wishes and skills of the customer.

Implementation of OPC UA Solutions with Peakboard.

Peakboard implements the OPC UA protocol in the context of a lightweight OPC UA client, which accesses the systems (OPC UA server) without any additional middleware. In this way, applications can be built that not only display machine data in real time, but also send commands back to the system from the Peakboard-Box or the connected touch screen (e. g. for controlling processes or acknowledging error states). Of course, machine data can easily be mixed and enriched with data from other data sources (e. g. SAP) in a board.

Usability.

With Peakboard the connection of OPC UA data becomes very easy. The dialog in the Peakboard-Designer guides the user through the individual configuration steps: from selecting the security standard to creating the variables to be read, which the user can simply click together. In addition to its high level of user-friendliness, Peakboard also offers comprehensive configuration options up to variable-specific modifications and further processing by Lua-Script.

Technical Background.

As usual for the OPC UA protocol, the Peakboard registers itself as a client on the server. The variables can be easily selected in the Peakboard-Designer via a browser dialog. These are later read by the Peakboard. Additionally, Peakboard offers the possibility to manage certificates, which can be created directly in the Peakboard-Designer. Importing and exporting are also supported.

Please note that the SHA1 algorithm was cracked in 2017 and is therefore no longer secure. Peakboard therefore currently solely provides the SHA256 algorithm for creating certificates. A feature of the OPC protocol is particularly advantageous in this context: the specification ensures that connection problems are registered by both the server and the client. This means immediate notification in case of disconnection if desired or at least appropriate logging.
Thus, the Peakboard can extract and visualize machine data very reliably. Typical scenarios arise from the display of key figures directly from the respective machines. These can be, for example, filling levels, cycle numbers / cycle times, reject rates or sensor data.
