6.3.7.7.- Display of variables
This parameter occupies 1 register.
Table 37:Modbus memory map: Conguration variables (Display of variables).
Selection of variables to be displayed
Configuration variable Address Valid data window Default value
Selection of variables to be displayed 2A94 – 2A95 0x00FF FFFF
(1)
0x00FF 0xFFFF
(1)
Each variable bit indicates the display (1) or not (0) of a parameter, see Table 38, where Bit 0 is the lowest bit
and bit 32 the highest.
The variable can never have a value of 0x0000 0000; one parameter must at least be displayed. The unit will
return a frame error if this happens.
