Pointe Controller User Guide Appendix C: Ladder Diagram Block Reference
369
Configuration Reference
The parameters of this block are described in the following table:
Param Name Config Var Type Description
EN Enable no - The state of the rung (off/on)
received from the left.
ENO Enable
Out no - The state of the rung (off/on)
passed to the right.
IN Input
Value req real only*
Numeric
The input value, in radians. If a
Numeric value is entered, it must
be real / floating.
OUT Output
Value req real only* The result of calculating the cosine
of the input value.
* Any 32-bit Real (F) Input, Output, or Memory tag. For more information, see “ Defining Input,
Output, Memory tags ” on page 114 .
C.3.9 Tangent (TAN)
When used in a Ladder Diagram, the TAN block finds the tangent 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 tangent 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.
