Description of the system

The company, which is engaged in the design, installation and maintenance of irrigation systems (including large stadiums, parks, hotel complexes, etc.), contacted us with a project to implement monitoring and diagnostics for important and remote sites. According to the idea, this system should provide independent access to the technological equipment for developers (without using of “remote desktops”, TeamViewer, etc., regardless of the operating personnel).

Project configuration before WebHMI application

Typical structure of the system in the example of a hotel complex includes two control cabinets for irrigation equipment with frequency converters and automation with the following automation facilities:

• PLC OWEN 160 – 2 pcs.
• SP270 panel OWEN 7 ” – 2 pcs.
• Acclima watering controller – 4 pcs.
• MasterSkada for one workplace

Obvious weaknesses of existing systems at the stage of monitoring implementation

1. Problems with communication channels. Often such objects are removed from civilization, there is not always an opportunity to connect to the wired Internet, also, often owners do not give external access to their networks to outside companies for security reasons.
2. The organization of a remote workstation for service access in SCADA requires the purchase of special modules for the existing server part, the purchase of another run-time SCADA license – systems for the remote workplace.
3. Absence of the upper level, where the data from the objects arrives. If there are several objects, their monitoring becomes cumbersome and not an easy task.
4. The facilities have already been commissioned and no one wants to interfere with the operation of the equipment.
5. SCADA only controls the automation, it’s not enough to understand the cause of the malfunction. For diagnostics, it would be best to access the Acclima Irrigation Controller directly with its service utilities.
