The checklist has 16 questions in five weighted categories: PLC programs (30%), HMI/SCADA screens (20%), frequency converters and drives (20%), access and documentation (15%), and responsibility and process (15%). Questions are rated 0–4 and the result is a weighted average of 0–100: below 40 is critical risk, 80 and above very good readiness.
Example: if only PLC (30%) and HMI (20%) are fully backed up and the rest are missing, the result is 50/100.
Frequently asked questions
Why is PLC program backup important?
If a controller fails and there is no fresh backup, restoring the machine can take days or weeks.
What should I back up?
PLC programs, HMI/SCADA projects, drive parameters and documentation of settings and passwords.
How often should I back up?
After every change and regularly. Keep copies in at least two separate places.

Methodology and limitations
Methodology based on standard industry calculations and Maintest’s practical industrial experience. This tool provides a planning estimate and does not replace project-specific engineering assessment. This tool is a screening and planning aid developed by Maintest. Results are indicative and depend entirely on the figures and answers you enter. They are not an engineering calculation, a safety assessment or a substitute for the manufacturer’s instructions, applicable standards or professional judgement. Weights, benchmarks and default values are Maintest planning assumptions and can be adjusted to your situation. Do not use this tool as the only basis for safety-critical decisions such as lifting, electrical work or lockout procedures.
