Modbus allows direct access to the RAM memory of the controller for writing the
controller set point value (0x3200), the controller actual value (0x3202) and the internal
analog values (0x3204, 0x3206) as well as the internal binary values (0x3208).
When writing, a range between -1999 and +9999 is available for the controller set point
values, controller actual values and the internal analog values. In this case, the data
written in the controller is used instead of the original value.
If you wish to use the original value again on the controller, write the value 200001 at the
memory location concerned via Modbus.
