What do you need to solve?
Problems we help solve
We start with the real symptom: a stopped CPU, an unstable network, inconsistent signals or equipment that no longer responds as expected.
Technical focus
Industrial technologies and areas covered by our work.
Siemens PLC
S5, S7-200, S7-300/400 and S7-1200/1500 systems.
Industrial networks
PROFIBUS, PROFINET and communication diagnostics.
HMI and SCADA
Operator interfaces, alarms, trends and process supervision.
Commissioning
Field signals, functional tests and controlled start-up.
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.
BOJ S7-PLC PRO
A clearer first response before opening STEP 7
Enter CPU states, LEDs and field symptoms. The app organizes technical hypotheses and suggests what to verify first.
- Symptom-based workflow
- Prioritized technical hypotheses
- Field verification guidance
Completed projects
Selected engineering, PLC migration and commissioning work completed in real production environments. Images are illustrative; clients and project scopes are real.
2024
BT40 engineering, field wiring and commissioning
A traceable start-up process with structured testing and clearer support for operation and maintenance.
2017
Fire protection system with Siemens S7-1500
The automated system was delivered with validated behavior and maintainable operating criteria.
2016
Migration from Siemens S5-95U to S7-1500
The plant moved to a maintainable platform with better support and diagnostic capability.
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
