10.4.2 Data Type Conversion Functions Convert to
Signed Integer
The Convert to Signed Integer function outputs the integer equivalent of BCD-4 or Real
data. The original data is not changed by this function.
When the function receives power flow, it performs the conversion, making the result
available via output Q. The function always passes power flow when power is received,
unless the data is out of range.

10.4.2.1 Parameters of the Convert to Signed Integer Function
Choices
flow
For BCD-4: I, Q, M, T, G,
R, AI, AQ,
constant
For REAL: R, AI, AQ
flow, none
I, Q, M, T, G, R, AI, AQ
10.4.2.2 Example
In the example, whenever input %I0002 is set, the BCD-4 value in PARTS is converted to
a signed integer and passed to the Addition function, where it is added to the signed
integer value represented by the reference RUNNING. The sum is output by the Addition
function to the reference TOTAL.

Description
When the function is enabled, the conversion is
performed.
IN contains a reference for the BCD-4, REAL, or
Constant value to be converted to integer.
The OK output is energized whenever enable is
energized, unless the data is out of range or NaN
(Not a Number).
Output Q contains the integer form of the original
value in IN.
