If it is necessary to write to the non-volatile memory excessively, please disable the
nonvolatile bit. The register is at relative address 24. It can be toggled back and forth
which allows the program to save the current state of the parameters into the
EEPROM at will.
Special Modbus Functions
The following are Modbus registers with special functions:
24 Disable Non-volatile (system) Memory (EEPROM)
110 Alarm Status Output 3
200 Auto-Manual Operation Mode

A "0" indicates an inactive state. Send "1" to the register to activate the function. It will
automatically reset to "0" when the function is complete.
