A machine or process has stopped
Fault isolation under production pressure.
INDUSTRIAL SERVICES
Diagnostics and engineering to restore and improve plant operation
PLC, HMI, SCADA, industrial networks, control panels and instrumentation. We organize the evidence, narrow down the likely cause and define the next technical step.
What do you need to solve?
Choose the starting point that best matches the current situation.
A PLC or HMI needs changes
Programming, online diagnostics and controlled modifications.
The industrial network is unstable
Node, connector, termination and communication analysis.
A legacy system must be modernized
Migration planning, signal survey, testing and commissioning.
How we can support your operation
Scope, typical applications and expected outcome for each core service.
Industrial fault diagnostics
Technical troubleshooting based on observable symptoms and field evidence.
Applications
- CPU STOP, SF or BF
- Intermittent faults

A method for making better technical decisions
From the symptom to a practical next step, with field evidence and a clear intervention scope.
Understand the symptom
Collect alarms, operating conditions and available field evidence.
Prioritize the cause
Separate PLC, network, hardware, signal and process-related possibilities.
Define the intervention
Set a clear scope, risk controls and the next technical action.
B2B software for generation
Turbine Copilot
Instrument history, inspection rounds and technical documents organized by unit and tag. Explore the workflow in a demonstration environment with sample data.HOW WE WORK
From the first message to the intervention
Scope, schedule, deliverables and cost are confirmed in a written proposal before any intervention.
First contact
Tell us the symptom, the equipment and what you have already observed; cabinet photos or online screenshots help. We reply within 48 business hours and urgent cases are coordinated on WhatsApp subject to availability.
Technical proposal
We define scope, schedule, deliverables and cost in writing. No charges outside the proposal.
Intervention and hand-over
On site or remotely depending on the case, with tests, technical documentation and a clear recommendation for operation and maintenance.
Who is behind BOJ
Walter Adrián Boj
Industrial automation specialist focused on Siemens PLC diagnostics, with more than 15 years in plants: maintenance, programming, industrial networks, migrations and real S7-300/400 faults. BOJ Automation and Control brings that field judgement to technical services, applied training and the BOJ S7-PLC app.
What technicians say
Real experience in the field.
Antes me costaba ordenar el diagnóstico cuando una CPU quedaba en STOP o aparecía BF. Con el curso entendí cómo analizar la falla por etapas y la app me sirve como guía rápida en planta. Hoy tengo más seguridad para intervenir sin empezar cambiando componentes al azar.Original testimonial in Spanish

Start with the symptom, the equipment and the evidence you already have
We can use that information to define scope, risk and the most useful technical next step.
