Complete revision the document How to Create module

This manual is made to help in building the modules for OpenSCADA. The module creation may be required if you wish to add the support for new data source or other extension to OpenSCADA. Since OpenSCADA is an extremely modular system, all interfaces of interaction with the external environment are implemented by expanding it with modules of following types:

• databases;
• communication interfaces, transports;
• protocols of the communication interfaces;
• data sources and data acquisition;
• archives-history (messages and values);
• user interfaces (GUI, TUI, WebGUI, speech, signal ...);
• additional modules, special.

The low level devices library of the DAQ-source templates appended by a template of the RDTech devices implementation

The RDTech (RuiDeng) UM24C, UM25C and UM34C are low-cost USB pass-through power measurement devices, and support a decent number of collection features, as well as full control via Bluetooth. This template implements most exposed commands and data collection available by the device's Bluetooth interface.

This template in first time uses the new output transports connection function SYS.Transport.outAt() and the Bluetooth interface for the data acquisition.

Total complexity: 0.3 HD

Common Conception of the Data Storage

The Data Storage in OpenSCADA initially built on different Data Bases and the Configuration File for the common, but interaction between these essences was not very clear also as managing the storage data between different storages.

So, in version 0.9.5 there was performed the storage unification what provides in whole for:

• direct storage and specifying the Generic Storage "*.*" as a combination of the Configuration File and the work Data Base;

• control for the data presence on different storages and providing for a function of managing-removing only data without the control object and from previous storages; priority of the DBs in their accessing;

• limiting of all configured-selected Data Bases only by the form "{Type}.{DB}" without a table here, that specified-bound to the object ID;

• all the data accessing functions moved under the conception.[more]

Changes in the OpenSCADA execution environment and the Automation Linux Distributive

There, during of months of the OpenSCADA 0.9.5 releasing, performed significant changes in the execution environment and the Automation Linux Distributive:

• appending a new Debian 11 release for OpenSCADA build and as a new base for the Automation Linux Distributive;

• updating the TDE stable release to 14.0.11 and 14.0.12, with fixing some its additional issues and packages;

• appending a new Ubuntu 22.04 release for OpenSCADA building;

• appending a new hardware platform ARM64 on the Debian 11 base (not tested);

• removing-disabling of building for the Maemo 5 (Nokia N900) platform since the cross-compiler crashes constantly at least in two places of the OpenSCADA source code.[more]

Debian Linux 11 + ARM64

Appended of building for the hardware platform ARM64, that was also tested on RPi3 and Siemens IOT2050.

At releasing the Debian Linux version 11 in 19.08.21 the OpenSCADA project was adapted to this version in:

- creating the proper building chroot-archives;

- building up the OpenSCADA packages;

- expanding the Automation Linux repository and building the new Live Disks;

- expanding the automatic builder for building the packages and Live Disks.

The FIFTH update to the production release of OpenSCADA 0.9 LTS

The update 0.9.5 (22.02.2022) to the production release of long term support (LTS) targets to upgrade present installations of the production version for fix known for now problems and expand its to some improvements with operative services updates providing here for signed to the technical support service users.

Generically the update fixes about 50 bugs and appends MANY improvements with a pair of significant-conceptual ones ...[more]

Necrolog of Tischenko Mykola Tarasovych

Mykola Tarasovych Tyshchenko took an implicit but significant part in the creation of this project as he was the director of "DIYA" LTD (1990 ... 2021), where the author of the project was currently working (1997...2020). Although direct official support of the project was never provided, nor was funding provided, but various automation equipment was purchased for the project, information resources of the project were hosted on the company's server (2004...2016), funded participation-reports at conferences and automation systems and scientific topics for practical implementation and testing were provided.[more]

Changing the registration conditions and rules on the OpenSCADA site

There was enabled the user registration approving by the site administrator and was changed Internet-channel of the OpenSCADA server, hence provided conditions to the registration public information.[more]

DAQ.Siemens — the Simple DAQ-Parameters type and data areas of ISO-TCP

The module DAQ.Siemens appended for the Simple type of the DAQ-Parameters support.

Also the module appended for the data area specifying as a negative DB with code of this area, and the Flags/Marks processing (0x83) added in a specific way, by the prefix "F".

Enabled for the parameters hierarchical including.

Fixed in sending the opening connection requests at the connection lost in the ISO-TCP own implementation.

A serie of significant improvements of the module {DAQ,Protocol}.OPC_UA

{DAQ,Protocol}.OPC_UA appended for the Publish service implementation, CHUNKS support on the DAQ-client part and the code coming refactoring in generic.

After the 0.9.4 LTS releasing that appended already for the Logical type DAQ-Parameters support and the Standard type DAQ-Parameters appended for the no requesting the metadata on the server mode and the attributes direct ID and name.
