Operand 1 Operand 2
Output
(Output, flag)
Optional Optional COS Variable
number
Data ZR
[Function] Assign the cosine of the data specified in operand 2 to the variable specified in operand
1.
The output will turn ON when the operation result becomes 0.
The setting in operand 1 must be a real variable in a range of 100 to 199, 1100 to 1199,
300 to 399 or 1300 to 1399.
The unit of data in operand 2 is radian.
(Note 1)
Radian = Angle x
 
