Automation and SCADA is an integrated system that lets you monitor and control measurement and control points in the field from a single center. For process automation, smart grid, substation and power plant applications, Devpan provides software design, hardware installation, system integration, commissioning and testing from a single source.
One Package, One Point of Responsibility
The most common problem in automation projects is fragmentation: one company writes the software, another builds the panel and a third team wires the site. When responsibility is split, gray areas appear where nobody can answer when a fault occurs.
That is why Devpan treats the project as a whole. In the hands of our experienced engineers, the customer’s needs and current problems first become an architecture and then a working system. Hardware and software are selected for the project, integrated and delivered as a complete package.
We are vendor-independent. That means we can build on your existing infrastructure instead of replacing it, and choose hardware that fits your spare parts policy.
Our Scope of Services
Software Design
Project-specific development of PLC, RTU and HMI software, including interlocking logic and automatic sequences.
Hardware Installation
Selection, mounting and wiring of control panels, I/O modules, communication hardware and field equipment.
System Integration
Bringing devices of different brands and protocols together in one system and connecting them seamlessly to existing infrastructure.
Commissioning and Testing
Point-to-point I/O verification, scenario tests, and execution of FAT and SAT protocols.
SCADA and HMI Screens
Screen design that lets operators see the status at a glance and follow alarms and trends.
Remote Monitoring and Reporting
Secure remote access, automatic report generation, and tracking of energy consumption and efficiency.
Field data only turns into decisions on a readable screen.
Measurements, status and alarm information collected through the PLC are shown on SCADA screens in the same layout as the actual process flow, so the operator sees at a glance which equipment is in which state.
Because trend and alarm history are recorded, post-fault analysis is based on data, not guesswork.
Access levels are defined per user; critical commands are only available to authorized operator accounts.
Screens are delivered together with the PLC address list and tagging logic; during commissioning, every signal is verified one-to-one with the field and any corrections are recorded in the project file.
Automation Architecture: Four Levels
Industrial automation systems are built in layers. Each layer is responsible for its own task and passes only the data needed to the layer above. This separation makes the system both secure and expandable.
The field level interfaces with the physical world: sensors measure, actuators move. The control level makes decisions with PLCs and RTUs; interlocking logic, automatic transfer and load-shedding sequences run here. The supervisory level collects, visualizes and archives data with SCADA software. The enterprise level connects this data to reporting, energy management and corporate systems.
Supported Communication Protocols
The success of an automation project depends on devices from different manufacturers speaking the same language. The protocols below are widely used in our projects.
| Protocol | Medium | Typical use |
|---|---|---|
| Modbus RTU | RS-485 serial line | Reading energy analyzers, protection relays and drives from the panel |
| Modbus TCP | Ethernet | Fast data exchange between PLC and SCADA, device network integration |
| IEC 61850 | Ethernet (MMS / GOOSE) | Substation automation, horizontal communication and interlocking between IEDs |
| IEC 60870-5-104 | Ethernet / TCP-IP | Connecting distribution networks to the central control center (SCADA) |
| DNP3 | Serial / Ethernet | Remote unit communication in power distribution and water infrastructure |
| PROFIBUS DP | RS-485 | Field device and drive communication in existing process plants |
| PROFINET | Industrial Ethernet | High-speed machine and line automation |
| EtherNet/IP | Industrial Ethernet | Device and drive integration at the control level |
| OPC UA | Ethernet / secure session | Standard data exchange between SCADA and MES, ERP and reporting systems |
| MQTT | TCP-IP / cloud | Connecting remote sites to a central monitoring platform with low bandwidth |
Standard Functions of Our SCADA Software

The Commissioning Process
Commissioning is the stage that proves the software really works on site. The six steps below are applied in the same order on every project.
- Freezing the I/O listAll inputs, outputs and communication points are listed with their tags and approved by the customer.
- Preparing the softwarePLC logic, HMI screens and the SCADA database are developed from the I/O list and pre-tested by simulation.
- Factory acceptance test (FAT)Scenario tests are run with the panel while all signals are simulated; shipment does not start until all findings are closed.
- Site installation and wiring checkPanels are positioned, field cables are pulled, and continuity and insulation are checked terminal by terminal.
- Point-to-point verificationEach sensor and actuator is triggered in the field to confirm it appears correctly on the SCADA screen.
- Commissioning, training and handoverThe system is run under load, operators are trained, and documentation and backups are handed over.
Cybersecurity and Access Management
Automation systems are no longer isolated networks. As remote monitoring and enterprise integration grow, security becomes an integral part of the design.
- Network segregation: The automation network is physically or logically separated from the office network, and traffic between them passes through a firewall.
- Default passwords: Factory passwords on PLCs, HMIs, switches and relays are always changed during commissioning.
- Role-based access: Monitoring, operation and engineering rights are separated; critical commands require a second confirmation.
- Remote access: No device is left directly exposed to the internet; access is only via VPN and logged sessions.
- Backups: Project files, the SCADA database and device configurations are backed up regularly and restores are tested.
- Audit trail: Who changed which value, and when, is recorded in a tamper-proof way.

Frequently Asked Questions
What is SCADA and what is it used for?
SCADA (Supervisory Control and Data Acquisition) is a system that collects data from field devices, presents it visually to the operator and allows remote control when needed. Its purpose is to make a facility monitorable and manageable from a single center.
What is the difference between automation and SCADA?
Automation is the layer that runs the process automatically with controllers such as PLCs or RTUs. SCADA sits above it: it does not control, but monitors, records, reports and gives the operator the ability to intervene. The two work together.
In which sectors do you carry out automation projects?
Our main application areas are process plants, power generation and distribution facilities, substations, water and wastewater infrastructure, building and infrastructure facilities, and telecommunication systems.
Is integration possible without replacing our existing system?
In most cases, yes. If existing PLCs, relays and analyzers can be read over a supported protocol, a SCADA layer can be added without renewing the system. Where a protocol converter is required, a suitable gateway solution is designed.
Do you work with a specific brand?
No. Hardware and software are selected according to the project requirements, the existing infrastructure and the customer’s spare parts policy. Being vendor-independent lets us design the most suitable solution.
Do you support IEC 61850?
Yes. In substation automation projects we implement IEC 61850 MMS and GOOSE communication, including interlocking and fast protection signaling between IEDs.
How long does commissioning take?
It depends on the number of points, the state of site preparation and the commissioning strategy. Instead of quoting a fixed time, we prepare a phased commissioning plan based on the signal list, site access and the time windows in which production can be stopped.
Do we receive the source code at the end of the project?
Yes. PLC and HMI project files, the SCADA configuration, I/O list, screen documentation and test protocols are handed over to the customer. We want your system to remain independently manageable.
Do you provide support after commissioning?
Yes. We offer remote support during the warranty period and, on request, a maintenance agreement, software updates and on-site service.
