Process data exchange

The b maXX process data can be read by Modbus register 2 to 65 (actual process data)
and can be wirtten by Modus register 102 to 165 (set process data). The parameters are
selected depending on the process data mapping (see
46).
Parameters are mapped not before state Operational on the process data register (see
ZOperational–
In state Operational the process data is written cyclically to the Modbus register and is
read ´cyclically from the Modbus register.
Each parameter is mapped to two 16 bit Modbus register.
