Are there any limitation in turning Master Relay ON-OFF (every minute).
Can it be used as safety?

The master control relay may switch arbitrarily often; it could switch every cycle, if you wanted.
If your system has the potential to seriously injure or kill someone, or to destroy something expensive, then I do not advise relying on software for safety. It would be better to design hardware interlocks, so that the system is safe no matter how the microcontroller behaves.

for safety, you need to use safety devices that are approved, they are very expensive
