D5 - Overview of Registers 8AI eco Module
In the following descriptions of the register settings,
default values
, if any, are
highlighted
. These settings
are suitable for most applications and at the initial commissioning.
The values in the underlined registers are stored in non-volatile memory. These registers should not be
written continuously.
(
*
)
The registers marked with this asterisk can be read or written only individually, not as a
contiguous block.
R501
Register
Values of the analog inputs
…
Each register contains the value of an analog input.
Important:
The values read from these registers should be
handled as
SINT (signed integer)
, because depending on the
configured sensor type, the characteristics of the sensor is
already taken into account and the measurement can lead to the
display of negative values (below 0°C).

(AI8
… AI1) The bits of this register are set when the value of an analog
input has changed by more than the value of the delta
determined in registers R1591...R1598. When the register has
been read, all bits are automatically reset to zero. Each analog
input is assigned to a bit of the register. The least significant bit
is associated with analog input No. 1, followed by the other ones
up to analog input No. 8.

Register
Delta value for the analog inputs
…
Each register contains the value by which an analog input has to
change, in order that the change will be indicated by the flag in
register R500. The value of Delta is of the same dimension as
the analog value itself (R501 ... R508). If Delta is zero, the
changing flag never will be set.
