11. Parameters accessible with Function Code 04

Function code 04 provides read access to the read-only input registers. The input registers contain the
signals of the UDA2182.

11.1 Signals

Signals provide a means for the user to remotely read status values within the UDA database. In the
function block model, you can think of them as values connected to the output of function blocks. Since
they are controlled by the function block algorithm, they are read-only. Signals can be either analog
(floating-point) or digital (long) depending on the type of output it is monitoring. They are permanently
connected to the function block outputs. In other words, the user doesn't have to configure the connection
to make the output visible. The output value is always visible.

11.2 Input Registers Map

Table 11-1 describes the input register map for Function Code 04.
Conversion between Address (Hex) Number and Register (Decimal) Number
To convert the address number to the register number, convert the address from hexidecimal to decimal
and add 30,001. Registers are addressed starting at zero: registers 30,001-30,016 are addressed as 0-15. To
convert the register number to the address number, subtract 30,001 from the register and convert to hex.
