Param Name Config Var Type Description
IN2 Input
Value 2 req any integer*
T_DONE
T_VALUE
T_PREVAL
Numeric
The second input value, which is
divided into the first input value.
OUT Output
Value req any integer* The result of calculating the square
root of the input value.
* Any Input, Output, or Memory tag except 32-bit Real (F) or Bit (X). For more information, see
“
Defining Input, Output, Memory tags ” on page 114 .
NOTE: This function does not check for bit register overflow. You can assign any
variables you wish, but mixing variable sizes – for example, a 32-bit input and an
8-bit output – may result in unusable output.
C.3.7 Sine (SIN)
When used in a Ladder Diagram, the SIN block finds the sine of an input and
sends the result to output.
Select the tool (from the Math Blocks toolbar) and click on a ladder rung to
insert the following block:
Once the block is inserted, you can double-click on it to configure it.
Functional Description
This block always passes the Enable input state (EN) through to the Enable Out
output state (ENO) without change; when EN becomes on, ENO is turned on, and
when EN becomes off, ENO is turned off.
When EN becomes on, the block function is executed: the sine of the Input Value
(IN) is calculated and the result is placed in the Output Value (OUT). The input
must be specified in radians.
The block function is executed every time the ladder is scanned , so long as EN
remains on. If EN becomes off, then OUT remains at its last calculated value until
EN becomes on and the block function is executed again.
