Free SCADA / HMI software

Here we listed SCADA and HMI software, which is fully free or has limited functionality.
SCADA or HMI software is not a full control system, but rather focuses on the supervisory level. As such, it is a purely software package that is positioned on top of hardware to which it is interfaced, in general via Programmable Logic Controllers (PLCs), or other commercial hardware modules.

Free SCADA – how to connect Excel to Allen Bradley CompactLogix PLC

If you have Microsoft Excel you can read and write data from Allen Bradley PLC ( CompactLogix or ControlLogix processor) using the DDE/OPC capabilities of RSLinx.
So how this free SCADA works?
In this example I am going to use Allen Bradley CompactLogix PLC 1769-L35E . I have RsLinx Classic ( no Lite – Lite edition does not support DDE ) and of course Microsoft Excel 2007.

First we need to open our RSLogix5000 project and create global tags (controller tags). I am going to use 2 tags from our last article about PLC Ladder Logic programming. Tags ORDER and TEMPERATURE have already some values. For testing purposes you can enter any values too.

They are arrays of 10. Create tags ORDER as DINT[10] and TEMPERATURE as REAL[10].


When tags are ready we have to open RSLinx software and create DDE/OPC topic. My PLC topic is OFFICE. Right click on your processor and select Configure New DDE/OPC Topic.






Remember you topic name (mine is OFFICE) as you need it later to enter in our VB code in Excel. Click apply and close the program. Open Excel and create Command Button. If you cannot find Command Button go to excel options and add it to your toolbar.



Together we need 2 buttons and table like on this picture below. Then right click on button and select View Code.



Enter now VB code for firs Read button.


Next is code for RSLinx communication



And finally Write button



Our free SCADA is ready to test now. Try to read values from PLC. Mine Excel table looks like this:

Quality control system in food industry

Production and storage process in food industry are subjected to specific laws related to quality control; the quality control system based on the Winlog Pro software SCADA platform has been successfully applied in many sectors of food industry; actually it gives the possibility to comply with requested quality control criteria limiting both the investment cost and the production loss due to the installation of the system.
The system provides a continuous monitoring of all the significant variables of the process and generates quality control reports with graphical trends that certify the compliance of the production lot; the system also certifies that the storage process doesn't affect the quality of the stored product and doesn't cause any modification of the original characteristics. Any abnormal condition in the production or storage process is promptly detected and signalled with a local alarm; in case of unattended environment, a SMS can be sent to the cellular phone of a maintenance staff operator.
All information generated can be made available to one or more Client stations (local or remote) linked via a TCP/IP protocol.

Winlog Lite, free SCADA HMI system

Winlog Lite is the "Entry level" version of the SCADA/HMI software Winlog Pro offered by Sielco Sistemi to its customers to allow an evaluation of the potentiality and the simplicity of use of the package; Winlog Lite is also a powerful and low cost solution for creation of small supervisory applications.

Winlog Lite makes available most of development tools and functions provided by the Winlog Pro software package, but limits the possibility to develop and to run applications up to a max of 24 tags. Winlog Lite does not include Symbol Factory library and Web Server support.

Winlog Lite can be executed both in Demo mode (without need of registration) and Full mode; in Demo mode, communication with external devices and sampling of external tags automatically stops after 15 minutes (if required, it can be restarted manually); in Full mode communication goes on without any limit of time.

To run Winlog Lite in Full mode, it is necessary to buy a license "Winlog Lite" and carry out the registration procedure; "Winlog Lite" license is valid only on the computer used to carry out the registration procedure and can't be transferred to another computer.

OpenSCADA – The OpenSource SCADA System

Image via Wikipedia

Scada systems are used for communication between software systems and the machines they control. The old monolithic Scada systems are being replaced by open, distributed environments, which provide a central overview of the whole system. Open protocols and network technology are applied to reduce costs while increasing quality and reliability of the system.

Scada systems are used for communication between software systems and the mashines they control. The old monolithic Scada systems are being replaced by open, distributed environments, which provide a central overview of the whole system. Open protocols and network technology are applied to reduce costs while increasing quality and reliability of the system.OpenSCADA® has taken this trend one step further: by providing an open SCADA platform, system limitation are overcome. This means OpenSCADA® is independent of technologies. Furthermore, integration is simple, it is highly configurable, meaning that creating a runtime environment is easy. The running system is readily extendible, and test and simulation environments are easily set up.

The Open Idea – Why OpenSCADA®?

The Open idea has several meanings in the OpenSCADA® Project:

Open architecture

Simple interfaces and a highly configurable environment enable quick development of a base system. Developed modules can be run and tested on the simulation system, which is also provided.

Open platform

OpenSCADA® is not limited to a certain Operating System (OS). The OS can be a system like Windows, Linux, MacOS, or Unix. You can chose the runtime Operating System independently.

Open development environment

OpenSCADA® is not limited to a development environment. Different projects are implemented in different environments, e. g. Java, C/C++, C#. By using the independent communication protocol, any programming language can be used to write OpenSCADA® components.

Open Source Code

Both the base modules and the extention modules are provided under the LGPL and GPL. The source code is open to everybody.
