Will SCADA Systems Survive? The Future of Distributed Management Systems
Will SCADA Systems
Survive? Or the Future
IIoT Platforms Vs. SCADA/HMI/MES
Contemporary SCADA and IIoT platforms have a lot of common features:
• Same data collection protocols
• Identical archive storage methods, while binary storage has gone to
• HMIs building is possible in both
• Similar ways of time-series data processing
Obviously, IIoT platforms offer all 4th
generation SCADA features (operation
in the cloud, web visualization, etc.)

IIoT Platform Advantages As Compared to SCADA
• Solving complex cross-domain tasks (IT infrastructure
management, fleet monitoring, service modeling, etc.)
• Collecting and processing not only tags but also
structured data (incident tables, service catalogs,
arbitrary object hierarchies and connections between
• Extensive support for multiple IT (Telnet/SSH, FTP), IoT
(MQTT, CoAP), and universal protocols (SOAP, CORBA)
• Complex data visualization (maps, statistical diagrams,
data-entry forms, OLAP cubes)
• Operation in publisher/subscriber mode, direct
communication between things

More Than SCADA
IoT platforms cover plenty of automation system levels:
• Almost every IIoT platform operates at SCADA/HMI
• Most platforms are able to solve MES and OEE tasks.
• Multiple platforms “feel all right” at ERP/EAM levels.
• In some cases, platform components enable SoftPLC
level, i.e. logic of controllers and IEC 61131-3 language
(FBD, LD, SFC, ST) runtime environment.
• There is a trend towards substituting DSC and niche
systems (e.g. AMR).

IoT Platform Operation at PLC Level
- 5 -
In Tibbo Project System hardware platform, AggreGate IoT Platform server acts
as a runtime environment providing data collection, storage, analysis, and
visualization at the controller level, as well as IEC 61131-3 (ST, LD, FBS, SFC)
algorithms execution in hard real time.
The server “feels all right” on Raspberry Pi, BeagleBone Black, other single-
board and industrial PCs, PLCs with Linux/Windows.
New Business Models
• Selling a service, not software, becomes commonplace.
• Paying not for time period/event count, but for the
service metrics (running hours, time saved on periodic
maintenance, etc.) will gain popularity.
• For setting up a service, a network (“tube”) and a server
(“cloud”) are needed. It automatically makes telecoms
the first potential IoT service providers.
• As in traditional IT, the value of data ownership in IoT
will increase compared to its simple transmission and
• Investment in device development is decreasing, while
investment in platform development is increasing fast.

Software of the Future Will Be Unified
• IoT platforms will take positions currently belonging to various lower
• The process will remind globalization of ERP systems that should be
able to do everything.
• It relates not only to a production sector, but to any other company
dealing with physical assets (agroholdings, retail, energy, oil and gas,
transport, and telecoms).
• Even in SCADA world, software will be offered as a service.
• Existing niche monitoring and management systems will either
transform into global solutions or exit the market.
