Prodiginvulgar programs PLCs, configures HMI operator panels and integrates SCADA systems for industrial production environments in Portugal and Europe. Over 30 years of experience with industrial control systems in automotive and aerospace manufacturing.
All ServicesA PLC (Programmable Logic Controller) executes the control logic that makes machines and production lines work automatically. An HMI (Human Machine Interface) gives operators visibility and control of the machine at the point of use. SCADA (Supervisory Control and Data Acquisition) provides plant-level monitoring, data collection and alarm management across multiple machines or an entire production facility. These three layers work together — PLC logic drives the process, HMI gives the operator control, and SCADA provides the plant manager with production data and status visibility. Effective integration of all three is essential for efficient, reliable and traceable industrial production.
Control system programming and integration from machine level to plant supervision — built for real production environments.
PLC program development for new machines and modifications to existing programs. Sequence logic, interlocking, safety logic, alarm configuration, production counting and data collection. Experience in real automotive and aerospace production environments, independent of control system brand.
HMI screen design and configuration for operator panels and touchscreens. Machine status displays, alarm screens, production data visualisation, recipe management and operator guidance — designed for usability in real production environments with shift workers.
SCADA system configuration and integration with PLC networks for plant-level production monitoring, alarm management, production reporting and data historian functions. Experience with WinCC and industrial SCADA platforms used in automotive manufacturing environments.
Systematic fault diagnosis of PLC-controlled machines using the PLC fault register, online monitoring, I/O signal verification and program logic analysis. Fast and accurate diagnosis that identifies root causes rather than treating symptoms — minimising production downtime.
Creation and organisation of control system documentation for PLC-controlled machines and systems — program documentation, I/O lists, network diagrams, alarm lists and operator manuals. Critical for maintenance team effectiveness and future modification projects.
A PLC (Programmable Logic Controller) is an industrial computer that controls machines and production processes by reading inputs from sensors and switches, executing a control program, and activating outputs such as motors, valves and actuators. PLCs are the backbone of industrial automation — managing sequences, interlocks, safety logic and production data collection in manufacturing environments. They are designed for continuous operation in industrial conditions including temperature variation, vibration and electrical noise.
An HMI (Human Machine Interface) is a local operator panel or touchscreen that shows the status of a machine and allows operators to control it directly at the point of use. SCADA (Supervisory Control and Data Acquisition) is a higher-level system that monitors and manages multiple machines or an entire plant from a central point, collecting data, displaying trends and managing alarms across the production environment. HMI is machine-level; SCADA is plant-level.
Yes. Prodiginvulgar works with industrial PLC and control systems regardless of brand or manufacturer. Experience covers PLC programming, HMI configuration and SCADA integration, developed through real projects in automotive and aerospace manufacturing. This includes new program development, program modifications, fault diagnosis and commissioning support.
PLC faults in industrial machines are caused by sensor failures, actuator problems, power supply issues, commúnication errors, I/O module failures, program logic errors and hardware failures. Effective diagnosis starts with the PLC fault register and alarm history, works backwards through the signal chain, and systematically isolates the root cause. Chasing symptoms rather than root causes wastes time and often introduces new problems during the repair process.
Some PLC program modifications can be made online without stopping production, depending on the control system and the nature of the change. Parameter adjustments, set-point changes and some additions to unused blocks can often be made online. Safety-critical changes, sequence logic modifications and changes that affect I/O signal states typically require the machine to be in a safe state. Each case must be carefully assessed before any online modification is attempted.
