Winlog Evo Code Builder: Programming SCADA Applications with a Proprietary Language

Modern SCADA systems are no longer limited to displaying process values, alarms and trends. Industrial automation applications increasingly require customized logic, automatic procedures, data processing and integration between different parts of the supervision system.

Winlog SCADA and OPC UA: Industrial Communication for Industry 4.0

Modern industrial automation requires more than simply collecting data from machines. A SCADA system for Industry 4.0 must connect PLCs, industrial devices, production software, databases and digital services while maintaining interoperability, scalability and secure data exchange.

Choosing the Right Modbus Gateway: SS10680-IOT-LOG vs. SS10680-MOD-LOG vs. SS10680-MOD

Industrial plants increasingly need to move data reliably between field devices and the systems that monitor them — whether that means a local SCADA application, a cloud dashboard, or a simple historical log on a USB drive. That data almost always starts on an RS485 serial network speaking Modbus RTU, while the systems consuming it increasingly expect Ethernet, Wi-Fi, or MQTT. Bridging that gap is the job of a Modbus gateway.

SCADA Remote Access: How Winlog Puts Your Plant in Your Pocket

Industrial operators no longer need to be standing in front of a control room panel to know what is happening on the plant floor. SCADA remote access has become a core requirement for modern supervisory systems, allowing engineers, maintenance teams and plant managers to monitor processes, acknowledge alarms and adjust setpoints from anywhere with an internet connection. Winlog, the SCADA/HMI software platform developed by Sielco Sistemi, addresses this need with three complementary tools for remote access to Winlog, designed to bring secure, real-time supervision to any browser or mobile device.

SCADA protocols guide: Modbus, OPC UA and reliable communications

A SCADA system is only as good as the data it can reliably collect, and that depends entirely on the communication protocols it supports. From decades-old serial links to modern IoT-oriented standards, SCADA protocols are the plumbing that connects PLCs, sensors and remote devices to the supervisory layer. This guide walks through the most important ones and explains how a platform such as Winlog Evo handles them in practice.

SCADA systems for oil and gas: monitoring, control and security

The oil and gas industry operates across widely scattered assets, from wellheads and pipelines to storage terminals and processing plants, often in remote or hazardous locations. SCADA systems for oil and gas give operators a single point of visibility and control over this distributed infrastructure, collecting field data, raising alarms and issuing commands to pumps, valves and compressors from a central control room. Winlog Evo, the SCADA/HMI platform developed by Sielco Sistemi, is used throughout this guide as the reference SCADA for describing how monitoring, alarming, reporting and integration come together in oil and gas operations.

SCADA for photovoltaic plants: solar monitoring, alarms and reporting

A photovoltaic power plant, whether a rooftop array or a utility-scale solar farm, only delivers its full value when its output is visible, verifiable and actionable in real time. A dedicated photovoltaic SCADA system collects data from inverters, meters, weather stations and trackers, turning scattered field signals into a single supervisory view of the plant. This is where SCADA for energy applications differ from generic industrial monitoring: uptime translates directly into revenue, and every hour of undetected downtime is lost production. Winlog Evo is a SCADA platform built to cover exactly this need, from a single plant to distributed portfolios.

SCADA for electrical grids and substations: remote monitoring and control

Electrical grids and substations sit at the heart of the energy sector, converting, transforming and distributing power across vast networks of lines, transformers, switchgear and protection relays. Supervising this infrastructure calls for a dedicated electrical substation SCADA system able to collect measurements, states and alarms from countless remote devices and present them as a single, coherent operational picture. Winlog Evo, the SCADA/HMI platform developed by Sielco Sistemi, is a concrete example of how such supervisory systems are built, deployed and secured for utilities and industrial power users who cannot afford blind spots in their electrical network.

SCADA for HVAC and building management: BMS, supervision and energy control

Chillers, air handling units, boilers, pumps, dampers and building-wide energy meters all need to be monitored, controlled and logged just as carefully as a production line. HVAC SCADA extends the same supervisory architecture used for industrial plants and infrastructure to heating, ventilation and air conditioning systems, giving facility teams real-time visibility, alarms and historical trends instead of a collection of disconnected local controllers. Winlog Evo, the SCADA/HMI platform from Sielco Sistemi, brings this level of supervision to HVAC and building automation projects, from a single air handling unit to multi-building energy programs.

SCADA for wind farms: wind turbine data, monitoring and supervision

A wind farm SCADA system collects, displays and archives the operational data produced by every turbine on a site, replacing dozens of disconnected local controllers with a single point of supervision. As installed wind capacity keeps growing worldwide, according to the International Energy Agency, operators increasingly need software that turns scattered turbine signals into an actionable, real-time picture of the whole plant. Winlog Evo, developed by Sielco Sistemi, is a SCADA platform built to unify turbine data, remote monitoring, alarms and reporting in one environment that scales from a handful of machines to a large wind farm.

SCADA vs HMI: supervision vs operator interface and how to choose

An HMI and a SCADA system are often mentioned in the same breath, and many people use the terms loosely, but SCADA vs HMI differences matter once a plant grows beyond a single machine. This guide explains what each one does, when one is enough, and how a platform such as Winlog Evo covers both roles as a project scales.

SCADA vs IoT/IIoT: strengths, differences and integration for Industry 4.0

As factories connect more sensors and devices than ever, SCADA vs IoT has become a real architectural question rather than a marketing debate. Both collect and expose field data, but SCADA and IoT/IIoT come from different traditions and solve different problems well. This guide compares their strengths and shows how a platform such as Winlog Evo bridges the two in a modern Industry 4.0 architecture.

SCADA vs PLC: real-time control vs supervision and data acquisition

PLC vs SCADA differences come up constantly in plant conversations because the two are almost always deployed together, yet solve very different problems: one controls, the other supervises. This guide explains what each does, how PLC SCADA integration works in practice, and when it is time to add a platform such as Winlog Evo on top of an existing PLC installation.

SCADA for water treatment plants: supervision, control and alarm management

Water and wastewater treatment plants combine pumps, valves, filters, dosing systems and water purification stages that must run continuously and within tight quality limits, often across sites spread over a wide service area. SCADA for water treatment plants brings this scattered equipment under one supervisory view, turning raw sensor readings into the alarms, history and reports that operators and regulators both need. Winlog Evo is a reference example of a SCADA/HMI platform built to cover this role from a single control room or remotely.

SCADA vs BMS: differences and selection criteria for industry and buildings

Both a SCADA system and a BMS (Building Management System) supervise equipment and collect data, yet they were built for very different worlds: industrial processes versus commercial and institutional buildings. Understanding SCADA vs BMS differences matters because choosing the wrong category of platform, or trying to force one into the other’s role, usually costs more than it saves. This guide compares both and shows where a platform such as Winlog Evo fits.

SCADA reporting and SQL integration: data structure, automation and traceability

Data that stays locked inside a SCADA system is only half useful; the other half of the value comes from turning it into SCADA reports that management can read and structured records that other systems can query. This guide covers how reporting and SQL integration work together to deliver both, using Winlog Evo as a practical reference.

Online SCADA training courses and certifications

SCADA training equips engineers, technicians and integrators with the practical skills needed to configure, operate and maintain supervisory control and data acquisition systems in real industrial plants. As factories, utilities and infrastructure operators rely increasingly on remote monitoring and data-driven decisions, structured SCADA training courses and certifications have become a standard step for anyone building a career in industrial automation. At Sielco Sistemi, Winlog Evo serves as the reference SCADA platform for hands-on practice, letting trainees move from tag databases and communication drivers to complete supervisory projects before ever touching a live plant.

SCADA alarms and trends: configuring event history, charts and dashboards

Raw process data only becomes useful once it is turned into alarms operators can act on, history they can audit, and trends they can diagnose from. SCADA alarms, event history, charts and dashboards are the tools that make this possible, and getting them right is often what separates a system operators trust from one they learn to ignore. This guide covers how to configure each of these areas in a platform such as Winlog Evo.

SCADA and ICS cybersecurity: vulnerabilities, testing and guidelines

SCADA cybersecurity is the discipline of protecting the industrial control systems that monitor and operate plants, utilities and critical infrastructure from unauthorized access, tampering and disruption. As SCADA platforms increasingly connect to corporate IT networks, cloud services and remote maintenance tools, the attack surface facing operators has grown far beyond the isolated, air-gapped systems of decades past. Solid SCADA security combines technical hardening, disciplined testing and adherence to recognized frameworks. Winlog Evo, the SCADA/HMI platform from Sielco Sistemi, is built with these requirements in mind and serves as the reference SCADA throughout this guide.

SCADA programmer and SCADA developer: role, skills and career path

A SCADA programmer — often called a SCADA developer — designs and configures the software that lets operators supervise, control and record data from industrial plants: process graphics, tag databases, alarms, trends and reports. The role sits at the intersection of automation, IT and process knowledge, working daily on platforms such as Winlog Evo to turn raw field signals into usable operator screens and plant history. Unlike a general software developer, a SCADA programmer must understand both the physical process being supervised and the constraints of industrial networks and hardware. This guide covers the skills, tools, training and career paths that define the profession, from first junior configuration tasks through senior integration and management roles.

Railway SCADA systems for railway infrastructure and plants

Railway networks combine traction power substations, signalling equipment, level crossings, tunnels, lighting and station plants spread across hundreds of kilometres, all of which need to be watched and coordinated from a single point of view. SCADA for transportation is exactly this: a supervisory layer that collects data from remote terminal units, PLCs and field sensors along the line and turns it into live dashboards, alarms and historical reports. Winlog Evo, the SCADA/HMI platform from Sielco Sistemi, is a reference example of how such systems are designed, deployed and secured in demanding rail environments.

PLC, DCS, SCADA and HMI differences: how they work and when to choose each

Few topics confuse newcomers to industrial automation as much as PLC vs DCS vs SCADA vs HMI. All four show up in the same conversations, sometimes in the same architecture, yet each solves a distinct problem. This guide explains what each layer does, the key differences between them, and how a platform like Winlog Evo fits into a typical automation architecture built from some or all of these building blocks.

Operational Technology: definition and the role of ICS and SCADA in industry

Operational Technology (OT) is the hardware and software that monitors and controls physical processes, equipment and infrastructure — from a bottling line to a power substation. Unlike office computing, OT exists to keep machines running safely and continuously, and it includes PLCs, sensors, actuators, and supervisory platforms such as Winlog Evo. As OT and IT networks increasingly connect for data exchange and remote access, understanding where OT starts and IT ends has become essential for both engineers and security teams.

CNC vs PLC: what they control, how they are programmed and when to use them

On a shop floor it is common to find a CNC and a PLC working side by side, yet the two controllers solve very different problems. A CNC (Computer Numerical Control) drives the precise, coordinated motion of machine axes, while a PLC (Programmable Logic Controller) manages the discrete logic, sequencing and safety of the surrounding equipment. Understanding CNC and PLC roles clearly is the first step to designing a reliable machine or line, and to knowing when to bring in a supervisory layer such as Winlog Evo on top of both.

SCADA software features: what to do and what to check before choosing

Choosing a SCADA software platform is not just about ticking a box next to “supervision and control.” It’s about understanding which features actually matter for your plant, your data, and your team — and which ones are marketing fluff. A modern SCADA/HMI system has to do far more than draw a mimic diagram on a screen: it has to collect data, generate reports, talk to aSQL database, expose a web client, manage alarms, and keep the whole system secure.

SCADA applications in industrial sectors: examples, benefits and monitoring goals

A SCADA system (Supervisory Control and Data Acquisition) is the backbone of modern industrial monitoring, giving plant managers a single, real-time view of production lines, machinery, and energy flows. From ceramics kilns to dairy production lines, from electrical substations to food safety checkpoints, SCADA applications now span virtually every industrial sector. This guide walks through why companies adopt supervisory control platforms, and shows practical examples of how a modern solution such as Winlog Evo is applied to production, quality, maintenance, and energy management across different industries.
