WARNING: Writable Modbus registers 
such as ‘0XXXX’ and ‘4XXXX’ directly 
reference the CD200D non-volatile 
memory. Non-volatile memory has a 
useful life of ~100,000 Write/Erase 
cycles. Any device writing to these reg-
isters must take care to not exceed the 
maximum number of Write/Erase cycles.
