One of the good features in A800/F800 inverters in mitsubishi is the built-in PLC

. you can do alot of stuff with it.
In one project, invisibly

I could block the inverter operation after a validity date expiration to save my right in the
last payment

.
Yesterday I received the final payment from the customer

, so today I am going to release the lock. I didn't need any
external units, any wiring and connections or any such complicated additions, all from the same inverter unit

.
I will be happy to share with this community the instruction manual for the built-in PLC with FR F800 inverter.
