The DSSA or DSEU bit at the corresponding display value configuration at address
256 to 286 has to be cleared to display the content of a display value register (see
Table 28 on Page 39). If the DSSA or DSEU bit is cleared this specifies that a display
value is used instead of a sensor value. The semantic meaning specifies which text is
displayed along with the specific display value. For an overview on this topic please
see Figure 6 on Page 21.
All registers are 16 Bit signed values. Depending on the modbus_unit specified with
the corresponding display value configuration register at address 256 to 287 (Table 28
at Page 39) the value needs to be scaled as described in Table 39 at Page 51 to achieve
the desired result.
